What is the Aiohttp MCP Server?

Tools for building Model Context Protocol (MCP) servers on top of aiohttp

What you get

Implements the MCP protocol natively — no heavy SDK dependencies. Only 3 runtime dependencies: aiohttp, aiohttp-sse, pydantic.

Native MCP protocol implementation (supports specs 2025-11-25, 2025-06-18, 2025-03-26)
Streamable HTTP transport with SSE streaming
Easy integration with aiohttp web applications
Tool, Resource, and Prompt support with decorator-based registration
Shared state via ctx.app and per-request data via ctx.request
Stateless by default, with optional stateful mode for server push and resumability

Configuration and credentials

Python 3.11 or higher - aiohttp >= 3.9.0, < 4.0.0 - aiohttp-sse >= 2.2.0, < 3.0.0 - pydantic >= 2.0.0, < 3.0.0
