proxy validates configuration on startup and will report errors for: + +- Invalid URLs or malformed endpoint addresses +- Conflicting transport settings +- Missing required authentication parameters +- Invalid file paths or permissions +- Out-of-range numeric values + +Example validation error: +``` +Error: Configuration validation failed + - Invalid endpoint_url: must use http:// or https:// protocol + - auth.client_id is required when using OAuth2 + - logging.max_file_size_mb must be between 1 and 1000 +``` + +## Best Practices + +### Security +- Store sensitive values (client secrets, tokens) in environment variables +- Use restrictive file permissions for configuration files containing secrets +- Avoid logging message bodies in production environments + +### Performance +- Use appropriate connection timeouts for your network conditions +- Enable connection pooling for high-throughput scenarios +- Configure reconnection settings based on server reliability + +### Monitoring +- Enable metrics collection for production deployments +- Use structured logging (JSON format) for log aggregation systems +- Set appropriate log levels to balance observability and performance + +### Maintenance +- Use configuration files for complex setups +- Document server-specific configuration requirements +- Test configuration changes in development environments first + +## Next Steps +

The proxy can automatically detect the appropriate transport or you can explicitly configure it. + +## Supported Transports + +| Transport | Protocol | Use Case | Bidirectional | Streaming | +|-----------|----------|----------|---------------|-----------| +| **HTTP** | HTTP/HTTPS | Standard request-response | No | No | +| **SSE** | Server-Sent Events | Real-time updates | No | Yes | +| **WebSocket** | WebSocket | Full-duplex communication | Yes | Yes | + +## Transport Auto-Detection + +The proxy automatically selects the appropriate transport based on URL patterns: + +```text +URL Pattern → Transport Type +───────────────────────────────────────────────── +ws://example.com → WebSocket +wss://example.com → WebSocket (Secure) +https://api.com/ws → WebSocket +https://api.com/websocket → WebSocket +https://api.com/sse → Server-Sent Events +https://api.com/events → Server-Sent Events +https://api.com → HTTP (Default) +``` + +### Auto-Detection Logic + +1. **Protocol Scheme**: `ws://` or `wss://` → WebSocket +2. **Path Contains**: `/ws`, `/websocket`, `/socket` → WebSocket +3. **Path Contains**: `/sse`, `/events`, `/stream` → Server-Sent Events +4. **Default**: HTTP transport for all other URLs + +## When to Use Each Transport + +### HTTP Transport +**Best for**: Traditional API servers, simple request-response patterns + +```toml +[transport] +transport_type = "http" +http_timeout_secs = 30 +http_max_redirects = 3 +``` + +**Advantages:** +- Universal compatibility +- Simple debugging and monitoring +- Works through most firewalls and proxies +- Stateless communication + +**Disadvantages:** +- No real-time capabilities +- Higher latency for frequent requests +- No server-initiated communication + +**Example servers:** +- REST API-based MCP servers +- Lambda or serverless MCP implementations +- Legacy systems with HTTP-only interfaces + +### Server-Sent Events (SSE) +**Best for**: Real-time updates, streaming data, server-initiated notifications + +```toml +[transport] +transport_type = "sse" +sse_reconnect_interval_secs = 5 +sse_max_retry_attempts = 10 +``` + +**Advantages:** +- Real-time server-to-client communication +- Automatic reconnection +- Works through HTTP infrastructure +- Efficient for streaming data + +**Disadvantages:** +- Unidirectional (server to client only) +- Limited browser connection pooling +- Requires persistent connections + +**Example servers:** +- Event-driven MCP servers +- Real-time data feeds +- Notification systems +- Live documentation servers + +### WebSocket Transport +**Best for**: Interactive applications, low-latency communication, bidirectional data flow + +```toml +[transport] +transport_type = "websocket" +websocket_ping_interval_secs = 30 +websocket_max_message_size_mb = 10 +``` + +**Advantages:** +- Full-duplex bidirectional communication +- Low latency +- Efficient binary and text data transfer +- Real-time interactive capabilities + +**Disadvantages:** +- Complex connection management +- Firewall and proxy complications +- Requires WebSocket-aware infrastructure + +**Example servers:** +- Interactive development environments +- Real-time collaborative tools +- Gaming or simulation MCP servers +- High-frequency trading systems + +## Transport Configuration + +### Global Transport Settings + +```toml +[transport] +# Force

Project Restructuring Summary - -## 📋 Overview - -This document summarizes the comprehensive restructuring of the Zed MCP Proxy project, transforming it from a single-file implementation into a well-organized, modular Rust project following modern software engineering best practices and MCP SDK guidelines. - -## đŸŽ¯ Objectives Achieved - -### 1. **Modular Architecture Implementation** -- Transformed monolithic `main.rs` (353 lines) into a clean, layered architecture -- Separated concerns across multiple focused modules -- Implemented proper dependency injection patterns -- Created clear boundaries between transport, protocol, and business logic - -### 2. **Enhanced Error Handling** -- Replaced ad-hoc error handling with comprehensive `thiserror`-based error types -- Added proper error chaining and context preservation -- Implemented error categorization for better debugging and monitoring -- Added retry logic classification for operational resilience - -### 3. **Configuration Management** -- Introduced strongly-typed configuration with validation -- Implemented builder pattern for flexible configuration construction -- Added comprehensive validation with meaningful error messages -- Created serializable configuration for future extensibility - -### 4. **Testing Infrastructure** -- Established comprehensive unit testing framework -- Created integration testing with mock MCP servers -- Added property-based testing capabilities -- Implemented performance and memory usage tests -

-examples/ # Configuration examples -docs/ # Documentation -``` - -## 🔧 Technical Improvements - -### Module Responsibilities - -#### **lib.rs** - Public API Layer -- Defines public interface and re-exports -- Provides version constants and utility functions -- Contains shared macros (`verbose_println!`) -- Serves as the main entry point for library usage - -#### **config/mod.rs** - Configuration Management -- **ProxyConfig**: Main configuration struct with validation -- **Builder Pattern**: Flexible configuration construction -- **Environment Integration**: Support for CLI args and env vars -- **Serialization**: JSON support for config files -- **Validation**: Comprehensive input validation with detailed error messages - -#### **error/mod.rs** - Error Handling -- **ProxyError**: Comprehensive error enumeration with `thiserror` -- **Error Chaining**: Proper source error preservation -- **Categorization**: Errors grouped by type for monitoring -- **Retry Logic**: Built-in retry classification -- **Conversion Traits**: Seamless error type conversions - -#### **proxy/mod.rs** - Core Business Logic -- **McpProxy**: Main proxy implementation -- **ServerHandler**: MCP protocol implementation -- **Connection Management**: Stateless connection creation -- **Message Bridging**: STDIO ↔ HTTP message translation -- **Error Handling**: Graceful degradation and recovery - -#### **transport/mod.rs** - Transport Layer -- **HttpTransportFactory**: Optimized HTTP client creation -- **Connection Pooling**: Efficient resource management -- **Configuration**: Transport-specific settings -- **Builder Pattern**: Flexible transport configuration -

-{"jsonrpc":"2.0","method":"tools/list",...} - -→ Automatic session handling -``` - -## Stateless Operation for Zed - -### Connection Pattern -- **Per-Request Connections**: Each MCP request creates a fresh HTTP connection -- **No Persistent State**: No client-side session caching between Zed invocations -- **Clean Shutdown**: Connections close immediately after response - -### Benefits for Zed Integration -1. **Matches Zed's Architecture**: Aligns with Zed's dynamic context server lifecycle -2. **Resource Efficiency**: No lingering connections or background processes -3. **Reliability**: Each request is independent, reducing failure propagation -4. **Simplicity**: No complex connection pooling or state management - -## Comparison with Alternative Approaches - -### ❌ URL Pattern Detection -```rust -// What we DON'T do: -if url.path().contains("/sse") { - use_sse_transport() -} else if url.path().contains("/ws") { - use_websocket_transport() -} else { - use_http_transport() -} -``` - -**Problems:** -- Fragile assumptions about URL structure -- Breaks when servers change endpoints -- Doesn't follow MCP specification -- Maintenance burden for URL patterns - -### ✅ Universal Streamable HTTP -```rust -// What we DO: -let transport = StreamableHttpClientTransport::with_client(client, config); -// Server determines response format automatically -``` - -**Benefits:** -- Robust and specification-compliant -- Works with any MCP-compliant server -- No URL assumptions needed -- Future-proof design - -## Configuration Examples - -### Basic Usage -```bash -# Works with any MCP-compliant endpoint -zed-mcp-proxy https://api.example.com/mcp -zed-mcp-proxy https://server.com/sse -zed-mcp-proxy https://service.com/events -``` - -### Zed Configuration -```json -{ - "context_servers": { - "any-mcp-server": { - "source": "custom", - "enabled": true, - "command": "zed-mcp-proxy", - "args": ["https://your-server.com/any-endpoint"], - "env": {} - } - } -} -``` - -## Error Handling - -### Connection Failures -- HTTP connection errors are reported immediately -- No retry logic (delegated to Zed's context server management) -- Clean error messages for debugging - -### Protocol Errors -- Invalid JSON-RPC messages are caught and reported -- Malformed SSE streams are handled gracefully -- Server-side errors are propagated correctly - -## Performance Characteristics - -### Latency -- **Cold Start**: ~100ms for new connections -- **Overhead**: <1ms protocol translation -- **Memory**: <10MB typical runtime footprint - -### Scalability -- **Concurrent Requests**: Unlimited (each is independent) -- **Connection Reuse**: HTTP/2 connection pooling when available -- **Resource Cleanup**: Automatic connection cleanup - -## Future Considerations - -### Potential Enhancements -1. **Connection Pooling**: Optional persistent connections for high-frequency usage -2. **Compression**: Gzip/deflate support for large payloads -3. **Authentication**: Enhanced OAuth2 and API key support -4. **Monitoring**: Built-in health checks and metrics - -### Maintaining Compatibility -- All enhancements will maintain current API compatibility -- Server-driven protocol negotiation will remain core principle -- Stateless operation for Zed integration will be preserved - -## Conclusion - -The universal Streamable HTTP approach provides: -- **Simplicity**: Single transport implementation -- **Reliability**: Specification-compliant behavior -- **Compatibility**: Works with all MCP-compliant servers -- **Maintainability**: No URL pattern updates needed - -This design choice prioritizes robustness and specification compliance over premature optimization, resulting in a proxy that works reliably with the entire MCP ecosystem. \ No newline at end of file diff --git a/docs/BADGES.md b/docs/BADGES.md deleted file mode 100644 index c965d89..0000000 --- a/docs/BADGES.md +++ /dev/null @@ -1,375 +0,0 @@ -# 📊 Badge System Documentation -

Test Pyramid Architecture - -Follow the testing pyramid to ensure optimal test distribution: - -``` - E2E Tests (5%) ← Few, expensive, high-value - Integration Tests (15%) ← Moderate, focused on interactions -Component Tests (30%) ← Many, isolated, fast -Unit Tests (50%) ← Most, granular, immediate feedback -``` - -**Guidelines:** -- **Unit Tests**: Test individual functions and methods in isolation -- **Component Tests**: Test modules and their internal interactions -- **Integration Tests**: Test complete workflows and external interfaces -- **E2E Tests**: Test critical user journeys through the entire system - -### 2. Test Quality Over Quantity - -**Focus on meaningful tests:** -```rust -// ❌ Bad: Testing implementation details -#[test] -fn test_internal_counter_increments() { - let mut processor = MessageProcessor::new(); - processor.increment_internal_counter(); - assert_eq!(processor.counter, 1); -} - -// ✅ Good: Testing behavior and outcomes -#[test] -fn test_processes_multiple_messages_correctly() { - let processor = MessageProcessor::new(); - let messages = vec![ - valid_tools_list_message(), - valid_ping_message(), - ]; - - let results = processor.process_batch(messages).unwrap(); - - assert_eq!(results.len(), 2); - assert!(results.iter().all(|r| r.is_successful())); -} -``` - -### 3. Test Independence and Isolation - -**Each test should be completely independent:** -```rust -// ❌ Bad: Tests depend on each other -static mut GLOBAL_STATE: i32 = 0; - -#[test] -fn test_first() { - unsafe { GLOBAL_STATE = 42; } - // ... test logic -} - -#[test] -fn test_second() { - unsafe { assert_eq!(GLOBAL_STATE, 42); } // Depends on test_first -} - -// ✅ Good: Each test sets up its own state -#[test] -fn test_message_validation_with_clean_state() { - let processor = MessageProcessor::new(); // Fresh state - let message = create_test_message(); - - let result = processor.validate(message); - assert!(result.is_ok()); -} -``` - -### 4. Clear Test Structure (AAA Pattern) - -**Arrange, Act, Assert - make tests readable:** -```rust -#[test] -fn test_json_rpc_error_response_validation() { - // Arrange - let error_response = json!({ - "jsonrpc": "2.0", - "error": { - "code": -32601, - "message": "Method not found" - }, - "id": 1 - }); - - // Act - let validation_result = validate_json_rpc_message(&error_response); - let is_response = is_response(&error_response); - let is_notification = is_notification(&error_response); - - // Assert - assert!(validation_result.is_ok()); - assert!(is_response); - assert!(!is_notification); -} -``` - -## Test Design Patterns - -### 1. Fixture-Based Testing with rstest - -**Use fixtures for consistent test data:** -```rust -#[fixture] -fn mock_server() -> MockServer { - MockServer::start() -} - -#[fixture] -fn valid_mcp_messages() -> Vec { - vec![ - tools_list_request(), - resources_list_request(), - ping_request(), - ] -} - -#[fixture] -fn test_config() -> ProxyConfig { - ProxyConfig { - endpoint_url: "http://localhost:8080".to_string(), - timeout: Duration::from_secs(30), - auth_config: None, - } -} - -#[rstest] -async fn test_batch_message_processing( - mock_server: MockServer, - valid_mcp_messages: Vec, - test_config: ProxyConfig -) { - // Test implementation using fixtures -} -``` - -### 2. Parameterized Testing - -**Test multiple scenarios efficiently:** -```rust -#[rstest] -#[case("tools/list", true)] -#[case("resources/read", true)] -#[case("prompts/get", true)] -#[case("", false)] -#[case("invalid-method", false)] -#[case("TOOLS/LIST", false)] // Case sensitive -fn test_method_validation(#[case] method: &str, #[case] should_be_valid: bool) { - let message = json!({ - "jsonrpc": "2.0", - "method": method, - "id": 1 - }); - - let result = validate_json_rpc_message(&message); - assert_eq!(result.is_ok(), should_be_valid); -} -``` - -### 3. Builder Pattern for Test Data - -**Create flexible test data builders:** -```rust -pub struct MessageBuilder { - message: JsonValue, -} - -impl MessageBuilder { - pub fn new() -> Self { - Self { - message: json!({ - "jsonrpc": "2.0", - "id": 1 - }) - } - } - - pub fn method(mut self, method: &str) -> Self { - self.message["method"] = json!(method); - self - } - - pub fn params(mut self, params: JsonValue) -> Self { - self.message["params"] = params; - self - } - - pub fn notification(mut self) -> Self { - self.message.as_object_mut().unwrap().remove("id"); - self - } - - pub fn build(self) -> JsonValue { - self.message - } -} - -#[test] -fn test_with_builder() { - let message = MessageBuilder::new() - .method("tools/call") - .params(json!({"name": "calculator", "arguments": {"op": "add"}})) - .build(); - - assert!(validate_json_rpc_message(&message).is_ok()); -} -``` - -### 4. Custom Assertions - -**Create domain-specific assertions:** -```rust -trait MessageAssertions { - fn assert_valid_json_rpc(&self); - fn assert_is_request(&self); - fn assert_is_response(&self); - fn assert_is_notification(&self); - fn assert_has_method(&self, expected_method: &str); -} - -impl MessageAssertions for JsonValue { - fn assert_valid_json_rpc(&self) { - assert!(validate_json_rpc_message(self).is_ok(), - "Message should be valid JSON-RPC: {}", self); - } - - fn assert_is_request(&self) { - self.assert_valid_json_rpc(); - assert!(self.get("method").is_some(), "Request should have method"); - assert!(self.get("id").is_some(), "Request should have id"); - } - - fn assert_has_method(&self, expected_method: &str) { - assert_eq!(extract_method_name(self).unwrap(), expected_method); - } -} - -#[test] -fn test_with_custom_assertions() { - let message = json!({ - "jsonrpc": "2.0", - "method": "tools/list", - "id": 1 - }); - - message.assert_is_request(); - message.assert_has_method("tools/list"); -} -``` - -## Quality Assurance - -### 1.

Refactoring with Test Safety - -**Safe refactoring practices:** -```rust -// Before refactoring - ensure comprehensive test coverage -#[cfg(test)] -mod pre_refactor_tests { - #[test] - fn test_current_behavior_comprehensive() { - // Document and test all current behaviors before changes - let all_test_cases = generate_comprehensive_test_cases(); - - for case in all_test_cases { - let result = current_implementation(case.input); - assert_eq!(result, case.expected_output); - } - } -} - -// During refactoring - maintain test compatibility -#[cfg(test)] -mod refactor_safety_tests { - #[test] - fn test_refactored_behavior_matches_original() { - let test_cases = load_recorded_behaviors(); - - for case in test_cases { - let old_result = case.original_output; - let new_result = new_implementation(case.input); - - assert_eq!(old_result, new_result, - "Behavior change detected for input: {:?}", case.input); - } - } -} -``` - -## Debugging and Troubleshooting - -### 1. Test Debugging Strategies - -**Effective debugging techniques:** -```rust -#[tokio::test] -async fn test_with_comprehensive_debugging() { - // Set up tracing for debugging - let _guard = tracing_test::TracingTest::new(); - - tracing::info!("Starting test with input: {:?}", test_input); - - // Use multiple assertion levels - let result = complex_operation(test_input).await; - - // Immediate assertion with context - assert!(result.is_ok(), "Operation failed: {:?}", result); - - let output = result.unwrap(); - - // Detailed state inspection - tracing::debug!("Operation output: {:?}", output); - tracing::debug!("Internal state: {:?}", get_internal_state()); - - // Multiple assertions with clear failure messages - assert_eq!(output.status, "success", "Unexpected status"); - assert!(!output.data.is_empty(), "No data returned"); - assert!(output.timestamp > 0, "Invalid timestamp"); - - // Property-based assertions - assert!(output.is_valid(), "Output failed validation"); -} -``` - -### 2. Common Test Issues and Solutions - -**Flaky tests:** -```rust -// ❌ Problematic: Time-dependent test -#[test] -fn flaky_time_test() { - let start = std::time::SystemTime::now(); - expensive_operation(); - let duration = start.elapsed().unwrap(); - - assert!(duration < Duration::from_millis(100)); // Flaky! -} - -// ✅ Better: Use deterministic time or mock -#[test] -fn stable_time_test() { - let mock_time = MockTime::new(); - let processor = ProcessorWithClock::new(mock_time.clone()); - - processor.start_operation(); - mock_time.advance(Duration::from_millis(50)); - processor.complete_operation(); - - assert_eq!(processor.operation_duration(), Duration::from_millis(50)); -} -``` - -**Resource leaks:** -```rust -// ❌ Problematic: Resource not cleaned up -#[tokio::test] -async fn leaky_test() { - let server = MockServer::start().await; - // Server not cleaned up - might affect other tests - test_with_server(&server).await; -} - -// ✅ Better: Explicit cleanup -#[tokio::test] -async fn clean_test() { - let server = MockServer::start().await; - - let result = test_with_server(&server).await; - - // Explicit cleanup - server.stop().await; - - assert!(result.is_ok()); -} - -// ✅ Best: Use RAII with Drop -struct TestServer { - server: MockServer, -} - -impl Drop for TestServer { - fn drop(&mut self) { - // Cleanup happens automatically - self.server.stop(); - } -} -``` - -### 3. Test Performance Issues - -**Optimizing slow tests:** -```rust -// Parallel test execution with rstest -#[rstest] -#[tokio::test(flavor = "multi_thread")] -async fn parallel_test_execution( - #[values(1, 2, 3, 4, 5)] worker_id: usize -) { - // Tests run in parallel, reducing total time - let result = simulate_work(worker_id).await; - assert!(result.is_ok()); -} - -// Shared fixtures to reduce setup cost -#[fixture] -#[once] -fn expensive_setup() -> ExpensiveResource { - // This runs once and is shared across tests - ExpensiveResource::new() -} - -// Conditional test execution -#[test] -#[ignore = "slow"] -fn expensive_test() { - // Run only when explicitly requested - expensive_operation(); -} -``` - -## Team Collaboration - -### 1. Test Code Reviews - -**Review checklist:** -- [ ] Tests follow AAA pattern (Arrange, Act, Assert) -- [ ] Test names clearly describe what is being tested -- [ ] Tests are independent and can run in any order -- [ ] Edge cases and error conditions are covered -- [ ] No hardcoded values without explanation -- [ ] Appropriate use of fixtures and test utilities -- [ ] Performance implications considered -- [ ] Documentation for complex test logic - -### 2. Test Documentation Standards - -**Documenting test intent:** -```rust -/// Tests the JSON-RPC message validation logic for edge cases -/// -/// This test ensures that our validator correctly handles: -/// - Messages with unusual but valid ID types (string, number, null) -/// - Different parameter structures (object, array, null, missing) -/// - Unicode content in method names and parameters -/// -/// Related issues: #123, #456 -/// Performance requirement: <1ms per validation -#[rstest] -#[case::string_id("test-id-123", json!({"param": "value"}))] -#[case::numeric_id(42, json!([1, 2, 3]))] -#[case::null_id(null, json!(null))] -fn test_json_rpc_validation_edge_cases( - #[case] id: JsonValue, - #[case] params: JsonValue -) { - // Implementation -} -``` - -### 3. Shared Test Utilities - -**Creating reusable test infrastructure:** -```rust -// tests/common/assertions.rs -pub trait JsonRpcAssertions { - fn assert_valid_request(&self); - fn assert_error_response(&self, expected_code: i64); - fn assert_method_matches(&self, expected: &str); -} - -// tests/common/builders.rs -pub struct TestScenarioBuilder { - // Builder for complex test scenarios -} - -// tests/common/fixtures.rs -pub mod fixtures { - pub fn standard_mcp_messages() -> Vec { /* ... */ } - pub fn error_scenarios() -> Vec { /* ... */ } - pub fn performance_datasets() -> HashMap> { /* ... */ } -} -``` - -## Tools and Automation - -### 1. Test Automation Scripts - -**Comprehensive test runner:** -```bash -#!/bin/bash -# scripts/test-comprehensive.sh - -# Run full test suite with reporting -./scripts/test-runner.sh \ - --coverage \ - --html-coverage \ - --property \ - --performance \ - --benchmarks \ - --junit \ - all - -# Generate reports -./scripts/generate-test-report.sh target/test-reports -``` - -### 2.

-The `zed-mcp-proxy` supports various authentication methods to securely connect to MCP servers. This guide covers OAuth2 setup, token management, and authentication troubleshooting. - -## Authentication Methods - -### 1. No Authentication -For public MCP servers that don't require authentication: - -```bash -# No additional configuration needed -zed-mcp-proxy https://public-mcp-server.com -``` - -### 2. OAuth2 Authentication -For servers requiring OAuth2, the proxy provides a complete browser-based authentication flow with secure token storage. - -### 3. API Key Authentication -Some servers may use API keys passed as headers (configured through the transport layer). - -## OAuth2 Setup - -### Automatic OAuth2 Detection - -The proxy automatically detects OAuth2 requirements for known providers: - -```bash -# Automatically detects OAuth2 for DevinAI -zed-mcp-proxy https://mcp.devin.ai -# Browser window opens automatically for authentication -``` - -### Manual OAuth2 Configuration - -For custom OAuth2 servers, create a configuration file: - -```toml -endpoint_url = "https://your-oauth-server.com" - -[auth] -# Required: OAuth2 client ID -client_id = "your-client-id" - -# Optional: Client secret (for confidential clients) -client_secret = "your-client-secret" -

-# Optional: Custom OAuth2 endpoints (auto-detected for known providers) -auth_url = "https://auth.provider.com/oauth2/authorize" -token_url = "https://auth.provider.com/oauth2/token" -``` - -### OAuth2 Flow Process - -1. **Initial Request**: Proxy detects authentication requirement -2. **Browser Launch**: Opens system browser with authorization URL -3. **User Authentication**: User logs in through OAuth2 provider -4. **Token Exchange**: Proxy receives authorization code and exchanges for tokens -5. **Secure Storage**: Tokens stored in system keyring/keychain -6. **Automatic Refresh**: Tokens refreshed automatically when they expire - -## Configuration Examples - -### DevinAI Server (Automatic) -```bash -# No configuration needed - OAuth2 auto-detected -zed-mcp-proxy https://mcp.devin.ai - -# With custom configuration -zed-mcp-proxy --config devin-config.toml https://mcp.devin.ai -``` -

-## Troubleshooting Authentication - -### Common Authentication Issues - -#### 1. Browser Doesn't Open -```bash -# Manual authentication flow -zed-mcp-proxy --log-level debug https://oauth-server.com -# Copy authorization URL from logs and open manually -``` - -#### 2. Invalid Client Error -```bash -ERROR OAuth2 flow failed: invalid_client -``` -**Solutions:** -- Verify `client_id` is correct -- Check if `client_secret` is required -- Ensure redirect URI matches server configuration -- Contact OAuth2 provider admin - -#### 3. Scope Not Granted -```bash -ERROR Access denied: insufficient_scope -``` -**Solutions:** -- Review requested scopes -- Check user permissions -- Request additional scopes from provider admin - -#### 4. Token Refresh Failed -```bash -ERROR Token refresh failed: invalid_grant -``` -**Solutions:** -- Clear stored tokens and re-authenticate -- Check if refresh tokens are supported -- Verify token hasn't been revoked - -#### 5. Redirect URI Mismatch -```bash -ERROR OAuth2 callback failed: redirect_uri_mismatch -``` -**Solutions:** -- Ensure redirect URI in config matches server -- Use `{port}` placeholder for dynamic ports -- Check for trailing slashes or protocol mismatches - -### Debug Authentication Flow - -```bash -# Enable detailed OAuth2 logging -zed-mcp-proxy \ - --log-level debug \ - --log-messages \ - https://oauth-server.com 2>&1 | grep -E "(oauth|auth|token)" - -# Test OAuth2 endpoints manually -curl -X POST https://auth.provider.com/oauth2/token \ - -H "Content-Type: application/x-www-form-urlencoded" \ - -d "client_id=your-id&client_secret=your-secret&grant_type=client_credentials" -``` - -### Authentication Logging - -```toml -[logging] -level = "debug" -format = "json" - -# Log authentication events (but not sensitive data) -log_auth_events = true -log_token_details = false # Never log actual tokens -``` - -## Security Best Practices - -### 1. Credential Management -- **Never commit secrets** to version control -- **Use environment variables** for production secrets -- **Rotate credentials** regularly -- **Use least-privilege scopes** - -### 2. Token Security -- **Use keyring storage** when possible -- **Set appropriate file permissions** for token files -- **Monitor token usage** and revoke unused tokens -- **Implement token rotation** policies - -### 3. Network Security -- **Use HTTPS** for all OAuth2 endpoints -- **Validate TLS certificates** properly -- **Configure corporate proxies** correctly -- **Use secure redirect URIs** - -### 4. Development Practices -- **Separate dev/prod credentials** -- **Test authentication flows** thoroughly -- **Handle auth errors** gracefully -- **Log security events** (without exposing secrets) - -## Example Configurations - -### Minimal OAuth2 Setup -```toml -endpoint_url = "https://mcp-server.com" - -[auth] -client_id = "your-client-id" -redirect_uri = "http://localhost:{port}/callback" -scopes = ["mcp:read"] -``` - -### Complete OAuth2 Configuration -```toml -endpoint_url = "https://enterprise-mcp.com" - -[auth] -client_id = "enterprise-client-id" -client_secret = "enterprise-secret" -redirect_uri = "http://localhost:{port}/callback" -scopes = ["mcp:read", "mcp:write", "admin:servers"] - -auth_url = "https://auth.enterprise.com/oauth2/authorize" -token_url = "https://auth.enterprise.com/oauth2/token" - -token_store = "keyring" -token_refresh_threshold_secs = 300 -max_refresh_attempts = 3 - -[transport] -connection_timeout_secs = 30 - -[logging] -level = "info" -log_auth_events = true -``` - -## Next Steps - -- [Token Management Guide](token-management.md) -- [OAuth2 Troubleshooting](troubleshooting/auth.md) -- [Security Configuration](advanced/security.md) -- [Integration Examples](examples/integration.md) \ No newline at end of file diff --git a/docs/src/configuration.md b/docs/src/configuration.md deleted file mode 100644 index 4b327d5..0000000 --- a/docs/src/configuration.md +++ /dev/null @@ -1,450 +0,0 @@ -# Configuration - -The `zed-mcp-proxy` provides flexible configuration options through TOML files, environment variables, and command-line arguments.

-## Command-Line Override - -All configuration can be overridden via command-line arguments: - -```bash -# Basic usage with config file -zed-mcp-proxy --config config.toml https://override-url.com - -# Override specific settings -zed-mcp-proxy \ - --config config.toml \ - --log-level debug \ - --log-format json \ - --metrics-port 9091 \ - https://mcp.example.com -``` - -## Configuration Validation - -The proxy validates configuration on startup and will report errors for: - -- Invalid URLs or malformed endpoint addresses -- Conflicting transport settings -- Missing required authentication parameters -- Invalid file paths or permissions -- Out-of-range numeric values - -Example validation error: -``` -Error: Configuration validation failed - - Invalid endpoint_url: must use http:// or https:// protocol - - auth.client_id is required when using OAuth2 - - logging.max_file_size_mb must be between 1 and 1000 -``` - -## Best Practices - -### Security -- Store sensitive values (client secrets, tokens) in environment variables -- Use restrictive file permissions for configuration files containing secrets -- Avoid logging message bodies in production environments - -### Performance -- Use appropriate connection timeouts for your network conditions -- Enable connection pooling for high-throughput scenarios -- Configure reconnection settings based on server reliability - -### Monitoring -- Enable metrics collection for production deployments -- Use structured logging (JSON format) for log aggregation systems -- Set appropriate log levels to balance observability and performance - -### Maintenance -- Use configuration files for complex setups -- Document server-specific configuration requirements -- Test configuration changes in development environments first - -## Next Steps -

This guide walks you through the essential steps to connect Zed editor to a remote MCP server. - -## Prerequisites - -- [zed-mcp-proxy installed](installation.md) on your system -- Zed editor installed and running -- A remote MCP server endpoint (we'll use a public example) - -## Step 1: Verify Installation - -First, make sure the proxy is installed correctly: - -```bash -zed-mcp-proxy --help -``` - -You should see the help message with version information and available options. - -## Step 2: Test Basic Connection - -Let's test the proxy with a simple HTTP endpoint: - -```bash -# Test connection to a public MCP server -zed-mcp-proxy https://mcp.deepwiki.com -``` - -If successful, you'll see connection logs. Press `Ctrl+C` to stop. - -**Expected output:** -``` -INFO Starting MCP Proxy for endpoint: https://mcp.deepwiki.com -INFO Connecting to remote endpoint... -INFO Both connections established, starting proxy -INFO Proxy started in 150 ms (full initialization: 200 ms) -``` - -## Step 3: Configure Zed Editor - -Now let's integrate the proxy with Zed. Edit your Zed settings: - -1. Open Zed -2. Go to **Settings** → **Open Settings File** (or press `Cmd+,` / `Ctrl+,`) -3. Add the MCP server configuration: - -```json -{ - "experimental": { - "mcp": true - }, - "mcp_servers": { - "deepwiki": { - "command": "zed-mcp-proxy", - "args": ["https://mcp.deepwiki.com"] - } - } -} -``` - -4. Save the settings file -5. Restart Zed - -## Step 4: Verify Integration - -Test that Zed can communicate with the MCP server: - -1. Open a new file in Zed -2. Try using MCP features (the exact features depend on your MCP server) -3. Check the Zed logs for successful MCP initialization - -You can also check the proxy logs by running it manually: - -```bash -# Run with verbose logging to see message exchange -zed-mcp-proxy --log-level debug https://mcp.deepwiki.com -``` - -## Step 5: Handle Authentication (If Required) - -Some MCP servers require OAuth2 authentication. If you see authentication errors: - -1. **For DevinAI servers** (automatic OAuth2 detection): - ```bash - zed-mcp-proxy https://mcp.devin.ai - ``` - A browser window will open for authentication. - -2. **For custom OAuth2 servers**, create a configuration file: - ```bash - # Create config file - mkdir -p ~/.config/zed-mcp-proxy - cat > ~/.config/zed-mcp-proxy/config.toml << EOF - endpoint_url = "https://your-oauth-server.com" - - [auth] - client_id = "your-client-id" - redirect_uri = "http://localhost:8080/callback" - scopes = ["mcp:read", "mcp:write"] - EOF - - # Use the config - zed-mcp-proxy --config ~/.config/zed-mcp-proxy/config.toml - ``` - -## Complete Example: DeepWiki Integration - -Here's a complete example using the DeepWiki MCP server: - -### 1. Test the connection: -```bash -zed-mcp-proxy https://mcp.deepwiki.com -``` - -### 2. Update Zed settings: -```json -{ - "experimental": { - "mcp": true - }, - "mcp_servers": { - "deepwiki": { - "command": "zed-mcp-proxy", - "args": [ - "https://mcp.deepwiki.com", - "--log-level", "info" - ] - } - } -} -``` - -### 3. Restart Zed and test MCP features - -## Common Transport Types - -The proxy automatically detects the transport type, but here are examples: - -```bash -# HTTP transport (default) -zed-mcp-proxy https://api.example.com/mcp - -# Server-Sent Events -zed-mcp-proxy https://api.example.com/sse - -# WebSocket -zed-mcp-proxy wss://api.example.com/ws -``` - -## Quick Troubleshooting - -### Connection Issues -- **Problem**: "Failed to connect to remote endpoint" -- **Solution**: Check if the URL is correct and the server is running -- **Debug**: Run with `--log-level debug` for detailed logs - -### Authentication Issues -- **Problem**: "Authentication required" or 401 errors -- **Solution**: Set up OAuth2 authentication (see [Authentication Guide](authentication.md)) - -### Zed Integration Issues -- **Problem**: MCP features not working in Zed -- **Solution**: - 1. Ensure `"experimental": {"mcp": true}` in Zed settings - 2. Check that the command path is correct - 3.

The proxy can automatically detect the appropriate transport or you can explicitly configure it. - -## Supported Transports - -| Transport | Protocol | Use Case | Bidirectional | Streaming | -|-----------|----------|----------|---------------|-----------| -| **HTTP** | HTTP/HTTPS | Standard request-response | No | No | -| **SSE** | Server-Sent Events | Real-time updates | No | Yes | -| **WebSocket** | WebSocket | Full-duplex communication | Yes | Yes | - -## Transport Auto-Detection - -The proxy automatically selects the appropriate transport based on URL patterns: - -```text -URL Pattern → Transport Type -───────────────────────────────────────────────── -ws://example.com → WebSocket -wss://example.com → WebSocket (Secure) -https://api.com/ws → WebSocket -https://api.com/websocket → WebSocket -https://api.com/sse → Server-Sent Events -https://api.com/events → Server-Sent Events -https://api.com → HTTP (Default) -``` - -### Auto-Detection Logic - -1. **Protocol Scheme**: `ws://` or `wss://` → WebSocket -2. **Path Contains**: `/ws`, `/websocket`, `/socket` → WebSocket -3. **Path Contains**: `/sse`, `/events`, `/stream` → Server-Sent Events -4. **Default**: HTTP transport for all other URLs - -## When to Use Each Transport - -### HTTP Transport -**Best for**: Traditional API servers, simple request-response patterns - -```toml -[transport] -transport_type = "http" -http_timeout_secs = 30 -http_max_redirects = 3 -``` - -**Advantages:** -- Universal compatibility -- Simple debugging and monitoring -- Works through most firewalls and proxies -- Stateless communication - -**Disadvantages:** -- No real-time capabilities -- Higher latency for frequent requests -- No server-initiated communication - -**Example servers:** -- REST API-based MCP servers -- Lambda or serverless MCP implementations -- Legacy systems with HTTP-only interfaces - -### Server-Sent Events (SSE) -**Best for**: Real-time updates, streaming data, server-initiated notifications - -```toml -[transport] -transport_type = "sse" -sse_reconnect_interval_secs = 5 -sse_max_retry_attempts = 10 -``` - -**Advantages:** -- Real-time server-to-client communication -- Automatic reconnection -- Works through HTTP infrastructure -- Efficient for streaming data - -**Disadvantages:** -- Unidirectional (server to client only) -- Limited browser connection pooling -- Requires persistent connections - -**Example servers:** -- Event-driven MCP servers -- Real-time data feeds -- Notification systems -- Live documentation servers - -### WebSocket Transport -**Best for**: Interactive applications, low-latency communication, bidirectional data flow - -```toml -[transport] -transport_type = "websocket" -websocket_ping_interval_secs = 30 -websocket_max_message_size_mb = 10 -``` - -**Advantages:** -- Full-duplex bidirectional communication -- Low latency -- Efficient binary and text data transfer -- Real-time interactive capabilities - -**Disadvantages:** -- Complex connection management -- Firewall and proxy complications -- Requires WebSocket-aware infrastructure - -**Example servers:** -- Interactive development environments -- Real-time collaborative tools -- Gaming or simulation MCP servers -- High-frequency trading systems - -## Transport Configuration - -### Global Transport Settings - -```toml -[transport] -# Force specific transport (overrides auto-detection) -transport_type = "sse" - -# Common settings -connection_timeout_secs = 10 -service_setup_timeout_secs = 5 -``` - -### HTTP-Specific Configuration -
