The extracted functions accept explicit sdk, kv, and config parameters so they can be reused by both the existing stdio transport and the upcoming Stream HTTP transport without code duplication. standalone.ts retains: - InMemoryKV instantiation - createStdioTransport and the stdio message dispatch loop - SIGINT/SIGTERM handlers - Backward-compatible wrapper exports (old signatures) for tests All 1410 non-integration tests pass; no behavioral changes.

SSE fallback is unnecessary. + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - MCP Stream HTTP Transport (Priority: P1) + +An MCP client (such as Claude Code, Cursor, or any MCP-compatible host) connects to agentmemory over HTTP to list and call memory tools. Instead of being limited to stdio (subprocess-based) connections, the client opens an HTTP connection to the agentmemory server and receives responses via a streaming transport — the server processes tool calls and streams results back incrementally as they become available, without waiting for the complete response. Since the deployment runs on a local network, the transport operates over plain HTTP (not HTTPS). + +**Why this priority**: This is the foundational change — without it, MCP clients are restricted to stdio connections, which prevents remote/containerized deployments and limits the integration options available to users. All existing MCP tool functionality (memory CRUD, search, sessions, etc.) must be accessible through this new transport. + +**Independent Test**: Start the agentmemory server with Stream HTTP enabled, send an MCP `initialize` request via `curl` to the stream endpoint, receive a valid JSON-RPC response with server capabilities, then call `tools/list` and `tools/call` over the same HTTP connection. Verify all 53 tools are listed and callable. + +**Acceptance Scenarios**: + +1. **Given** agentmemory server is running with Stream HTTP transport enabled, **When** an MCP client sends a JSON-RPC `initialize` request to the stream endpoint, **Then** the server responds with protocol version and capabilities including `tools: {}` support. +2. **Given** an initialized MCP session over Stream HTTP, **When** the client calls `tools/list`, **Then** the server returns the full list of available tools (53 tools with all features enabled). +3. **Given** an initialized MCP session over Stream HTTP, **When** the client calls `tools/call` with tool name `memory_search` and valid arguments, **Then** the server executes the search and returns the results as a JSON-RPC response. +4. **Given** both Stream HTTP and stdio transports are available, **When** a client connects via either transport, **Then** both transports expose the identical set of tools with identical behavior. + +--- + +### User Story 2 - Docker Compose Deployment (Priority: P2) + +A user wants to run agentmemory entirely in containers without cloning the source repository. They run a single `docker compose up` command, and the full stack starts — the agentmemory application and its iii-engine dependency — all from pre-built Docker images. No source code directories are bind-mounted into the containers; everything is baked into the images. + +**Why this priority**: Dockerization makes agentmemory deployable anywhere Docker runs, without Node.js or npm prerequisites. This unlocks production deployments, CI/CD integration, and self-hosted usage. + +**Independent Test**: On a machine with only Docker and docker-compose installed (no Node.js, no cloned repo), run `docker compose up`, wait for the services to report healthy, then `curl http://localhost:3111/agentmemory/livez` and receive `{"status": "ok"}`. Then use an MCP client to connect to the Stream HTTP endpoint and perform a memory save and recall. + +**Acceptance Scenarios**: + +1. **Given** Docker and docker-compose are installed, **When** the user runs `docker compose up`, **Then** both the iii-engine and agentmemory containers start and reach a healthy state. +2. **Given** the stack is running via docker compose, **When** the user sends a request to the MCP Stream HTTP endpoint, **Then** the request is processed successfully with streaming responses. +3. **Given** the agentmemory container, **When** inspected, **Then** no source code directories are bind-mounted; the application and all dependencies are self-contained in the image. +4. **Given** the docker compose stack is stopped and restarted, **When** the user runs `docker compose down` then `docker compose up`, **Then** previously stored memory data persists (via a named Docker volume). + +--- + +### User Story 3 - Single-Command Setup for New Users (Priority: P3) + +A new user with no prior agentmemory installation wants to get started. They download the `docker-compose.yml` file, run `docker compose up`, and within seconds the service is ready. They configure their MCP client with a single HTTP URL (no subprocess paths, no `npx` commands) and immediately have working memory in their AI coding sessions. + +**Why this priority**: Streamlined onboarding removes friction for adoption. This is the "it just works" story that turns a complex multi-step setup into two commands. + +**Independent Test**: On a fresh machine, create a new directory, download `docker-compose.yml`, run `docker compose up`, then configure any MCP client with `http://localhost:/mcp` as the connection URL and verify memory tools are available and functional. + +**Acceptance Scenarios**: + +1. **Given** a fresh environment with only Docker, **When** the user obtains the `docker-compose.yml` and runs `docker compose up`, **Then** within 30 seconds the service is ready to accept MCP connections. +2. **Given** the server is running in Docker, **When** the user follows setup instructions to connect their MCP client via HTTP URL, **Then** the client successfully connects and lists all memory tools. +3. **Given** the server is running in Docker, **When** the user checks the Docker image size, **Then** the agentmemory image is reasonably compact and optimized (no unnecessary build tools, no source code, no `node_modules` bloat). + +--- + +### Edge Cases + +- What happens when the iii-engine container starts after the agentmemory container? The agentmemory container must retry the engine connection with backoff until the engine is ready. +- How does the system handle concurrent MCP clients over Stream HTTP? Multiple clients must be able to maintain independent sessions simultaneously. +- What happens when a Stream HTTP connection is dropped mid-stream? The server must clean up session resources and not leak connections. +- How does the server behave when a client sends an invalid JSON-RPC message? Return a proper JSON-RPC error response without crashing. +- What happens to stored memory data when the Docker containers are rebuilt or updated? Data persists in the Docker volume and survives image updates. +- How does the container handle graceful shutdown when `docker compose down` is issued? Connections must close cleanly and data must be flushed. + +## Requirements *(mandatory)* + +### Functional Requirements + +- **FR-001**: The MCP server MUST support the Streamable HTTP transport as defined by the MCP specification, operating over plain HTTP — using a hand-rolled JSON-RPC server for direct JSON responses. +- **FR-002**: The new HTTP-based MCP transport MUST expose all existing tools (53 tools with `AGENTMEMORY_TOOLS=all`) with identical inputs and outputs as the existing stdio transport. +- **FR-003**: The existing stdio transport (JSON-RPC 2.0 over stdin/stdout) MUST continue to function alongside the new HTTP transport — both transports must coexist, including when running from within the Docker container. +- **FR-004**: The system MUST provide a complete Docker image for the agentmemory application that contains all runtime dependencies and the built application — no source code or `node_modules` directory mount from the host. +- **FR-005**: The system MUST provide a `docker-compose.yml` that defines and orchestrates both the agentmemory and iii-engine services, including correct startup ordering and health checks. +- **FR-006**: The Docker deployment MUST persist memory data in a named Docker volume, surviving container restarts and image updates. +- **FR-007**: The agentmemory container MUST gracefully handle the iii-engine container starting after it, with connection retries. +- **FR-008**: The MCP Stream HTTP endpoint MUST support concurrent client connections, each with independent session state. +- **FR-009**: Graceful shutdown MUST be handled — connections closed and data flushed on termination signals. +- **FR-010**: The Stream HTTP endpoint MUST require the same Bearer token authentication (`AGENTMEMORY_SECRET`) as the existing REST API, ensuring consistent access control across all transports. +- **FR-011**: The docker-compose.yml MUST default to exposing all 53 MCP tools (`AGENTMEMORY_TOOLS=all`) for a complete out-of-box experience. +- **FR-012**: On first container startup, if `AGENTMEMORY_SECRET` is not set, the container MUST auto-generate a random secret, persist it to a file on the data volume, and log instructions for retrieving it. + +### Key Entities + +- **MCP Session**: Represents an active client connection over the Stream HTTP transport. Key attributes: session identifier, initialization state, client capabilities, negotiated protocol version. +- **Docker Service (agentmemory)**: The containerized agentmemory application. Depends on the iii-engine service. Exposes MCP and API ports. +- **Docker Service (iii-engine)**: The containerized iii-engine backend. Provides state storage, pub/sub, and HTTP worker infrastructure to agentmemory. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: An MCP client can connect to agentmemory over HTTP, complete initialization, list tools, and call any tool — all without using stdio or spawning a subprocess. +- **SC-002**: All 53 MCP tools are accessible and functional through the new HTTP-based transport. +- **SC-003**: A user with only Docker installed can go from zero to a running agentmemory instance with a single `docker compose up` command. +- **SC-004**: The agentmemory Docker image contains no source code and requires no host directory mounts to function. +- **SC-005**: Memory data persists across `docker compose down && docker compose up` cycles. +- **SC-006**: The system handles at least 5 concurrent MCP client connections over Stream HTTP without errors or throughput degradation. +- **SC-007**: The existing stdio-based MCP transport continues to pass all existing tests after the HTTP transport is added. + +## Assumptions + +- The MCP Streamable HTTP transport is implemented as a hand-rolled JSON-RPC server using Node.js `http` module (not using `@modelcontextprotocol/sdk`) because the SDK's `NodeStreamableHTTPServerTransport` has a body-parsing bug with chunked transfer encoding. +- The `iii-engine` Docker image (`iiidev/iii:0.11.2`) remains the dependency — this feature does not modify or rebuild the iii-engine. +- The Stream HTTP endpoint (`POST /mcp`) is served on port 3114, separate from the existing REST API on port 3111. +- The existing deploy templates in `deploy/` (Fly, Railway, Render, Coolify) are out of scope for this feature — only a new Docker Compose setup targeting local/Docker-host deployments is required. +- Node.js is the runtime for the Docker image. Binary compilation via tools like Bun or `pkg` may be explored but is not required. +- The Docker image is built locally via `docker compose build` — no container registry publishing is required for the initial release. The `docker-compose.yml` includes the build context and Dockerfile reference. diff --git a/src/mcp/stream-http.ts b/src/mcp/stream-http.ts index 65e3e0f6c..1fc6a3b7c 100644 --- a/src/mcp/stream-http.ts +++ b/src/mcp/stream-http.ts @@ -12,9 +12,6 @@ * Streamable HTTP contract (protocolVersion "2025-03-26"). * * Observed in @modelcontextprotocol/node v2.0.0-alpha.2 with chunked transfer encoding. - * See: https://github.com/modelcontextprotocol/typescript-sdk/issues/187 - * - * Revisit this if the upstream SDK fixes the body-parsing issue. */ import { createServer } from "node:http"; diff --git a/tsdown.config.ts b/tsdown.config.ts index 9094961be..28076e09c 100644 --- a/tsdown.config.ts +++ b/tsdown.config.ts @@ -34,7 +34,6 @@ const shared = { "onnxruntime-web", "@anthropic-ai/claude-agent-sdk", "@anthropic-ai/sdk", - "@modelcontextprotocol/node", ] as const, };
