# RMCP

An official Rust Model Context Protocol SDK implementation with tokio async runtime.

> **Migrating to 3.x?** See the [migration guide](https://github.com/modelcontextprotocol/rust-sdk/discussions/969) for breaking changes and upgrade instructions.

This repository contains the following crates:

- [rmcp](crates/rmcp): The core crate providing the RMCP protocol implementation - see [rmcp](crates/rmcp/README.md)
- [rmcp-macros](crates/rmcp-macros): A procedural macro crate for generating RMCP tool implementations - see [rmcp-macros](crates/rmcp-macros/README.md)

This SDK implements the stable MCP **`2026-07-28`** specification while
remaining fully compatible with the **`2025-11-25`** release and earlier
versions. Features introduced in `2026-07-28` — server discovery & negotiation,
transport-neutral subscriptions, long-running tasks, response caching,
multi-round-trip requests, and standard HTTP routing headers — are documented
below. For the full MCP specification, see
