The new MCP server function template deploys a stateless Model Context Protocol server over HTTPS, built with the official MCP Python SDK. It ships with two demo tools, optional bearer authentication, and support for both the legacy MCP handshake and the stateless 2026-07-28 protocol.
Create it from the Console under Functions > Templates, and your function's domain becomes an MCP endpoint you can connect to Claude Code, Cursor, and other AI clients:
claude mcp add --transport http my-mcp https://<your-function>.appwrite.run
Register your own tools in src/app.py with the @server.tool decorator, and use the dynamic API key to build tools that read and write your Appwrite project's data.
Two trade-offs to know: the server is stateless JSON only, so there is no SSE streaming or server-initiated messages, and tool calls are synchronous with a 30-second execution cap (25-second soft deadline by default). The announcement covers both in more detail.
