MCP Client Compatibility

Last updated: June 24, 2025

This repository tracks which MCP (Model Context Protocol) clients support which parts of the protocol.

Anthropic included a compatibility table in their MCP launch docs, but it quickly became outdated. This open source repo exists so the community can help keep it fresh!
