+# 🔌 MCP Server
+
+Expose custom tools to AI clients (Claude Code, Cursor, and other MCP hosts) over HTTPS. Stateless [Model Context Protocol](https://modelcontextprotocol.io/) server on Appwrite Functions — official Python SDK (`mcp==2.0.0`), JSON-RPC over HTTPS. No SSE sessions.
+
+Edit `src/app.py` to register your own tools, deploy, and point Claude Code / Cursor at the function domain.
+
+## 🧰 Usage
+
+### POST /
+
+Accepts MCP Streamable HTTP JSON requests (legacy handshake and modern `2026-07-28`).
+
+**Headers**
+
+| Name                   | Description                                      | Location | Type   | Sample Value   |
+| ---------------------- | ------------------------------------------------ | -------- | ------ | -------------- |
+| Content-Type           | Must be `application/json`                       | Header   | String | application/json |
+| Accept                 | Prefer `application/json, text/event-stream`     | Header   | String | application/json, text/event-stream |
+| MCP-Protocol-Version   | Optional. Use `2026-07-28` for the modern path   | Header   | String | 2025-06-18     |
+| Authorization          | Required when `MCP_AUTH_MODE=bearer`             | Header   | String | Bearer s3cr3t  |
+
+**Response**
+
+Sample `200` — `initialize`:
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 1,
+  "result": {
+    "protocolVersion": "2025-06-18",
+    "capabilities": { "tools": { "listChanged": true } },
+    "serverInfo": { "name": "appwrite-hosted-mcp", "version": "0.1.0" }
+  }
+}
+```
+
+Sample `200` — `tools/call` echo:
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 3,
+  "result": {
+    "content": [{ "type": "text", "text": "pong" }]
+  }
+}
+```
+
+Sample `202` — notifications (empty body):
+
+```text
+(empty)
+```
+
+Sample `401` — bearer auth failure:
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": null,
+  "error": { "code": -32001, "message": "Invalid bearer token" }
+}
+```
+
+### OPTIONS /
+
+CORS preflight. Returns `204` with `Access-Control-Allow-*` headers.
+
+### GET /, DELETE /
+
+Not supported (no SSE streams, no sessions). Returns `405`.
+
+### Demo tools
+
+| Tool | Arguments        | Returns          |
+| ---- | ---------------- | ---------------- |
+| echo | `text: string`   | echoed string    |
+| add  | `a: float`, `b: float` | sum         |
+
+### Connect a client
+
+After deploy, add the function domain:
+
+```bash
+claude mcp add --transport http my-mcp https://<your-function>.appwrite.run
+```
+
+Or in Cursor / Claude Desktop `mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "my-mcp": {
+      "url": "https://<your-function>.appwrite.run"
+    }
+  }
+}
+```
+
+With bearer auth, set Function env `MCP_AUTH_MODE=bearer` + `MCP_AUTH_TOKEN=...` and pass:
+
+```json
+{
+  "mcpServers": {
+    "my-mcp": {
+      "url": "https://<your-function>.appwrite.run",
+      "headers": {
+        "Authorization": "Bearer your-long-random-secret"
+      }
+    }
+  }
+}
+```
+
+### Smoke test
+
+```bash
+curl -sS -X POST \
+  -H "Content-Type: application/json" \
+  -H "Accept: application/json, text/event-stream" \
+  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"smoke","version":"0.1.0"}}}' \
+  https://<your-function>.appwrite.run
+```
+
+### Write a tool
+
+```python
+# src/app.py
+from mcp.server.mcpserver import MCPServer
+
+server = MCPServer(name="my-mcp", version="0.1.0")
+
+@server.tool(description="Do something useful.")
+def my_tool(query: str) -> str:
+    return f"got: {query}"
+```
+
+Type hints become the tool `inputSchema`. Add `ctx: Context` to read inbound HTTP headers (including Appwrite's dynamic API key `x-appwrite-key`).
+
+Do **not** name the tools module `server.py` — Open Runtimes already ships a top-level `server` module.
+
+### Why this isn't `streamable_http_app()`
+
+Appwrite Functions are short-lived request/response workers. They do not run a Starlette lifespan, so `MCPServer.streamable_http_app()` raises `RuntimeError: Task group is not initialized`. This template drives the SDK's lower-level buffered entry points instead (legacy `serve_one` + modern `handle_modern_request`). Pin `mcp==2.0.0` exactly — those helpers are private and can move.
+

+| ------------ | ------ |
+| Required     | No     |
+| Sample Value | `25`   |
+
+### MCP_DEBUG
