MCP Protocol Library
MCPOpen SourceMIT42.7
by chrishayuk • Messaging & Collaboration
A lean, production-minded Python implementation of the Model Context Protocol (MCP) for building typed, async MCP clients and servers.
Example Use Cases
- 1
A typed, protocol-compliant way to discover and call server-exposed tools and functions over stdio or Streamable HTTP.
- 2
List, read, and subscribe to resources (files, DBs, APIs) with capability negotiation and optional runtime validation.
- 3
Integrate reusable prompt templates, sampling/completion requests, and progress/cancellation signalling in an async, transport-agnostic manner.
Description
chuk-mcp provides a transport-agnostic, spec-accurate protocol layer for MCP, delivering typed message models, capability negotiation, and helper functions for both clients and servers. It is async-first (AnyIO), supports stdio and Streamable HTTP transports, and optionally uses Pydantic for richer validation. The library is small, focused on protocol compliance, and intended for integrating AI applications with tools, resources, and prompt templates without imposing an opinionated application framework.
