Model Context Protocol SDK
MCP MCP server exists for a simple reason — assistants are far more useful when they can act on MCP directly instead of describing what you should do. Model Context Protocol SDK.
Python implementation of the Model Context Protocol (MCP)
The Model Context Protocol lets you build servers that expose data and functionality to LLM applications in a secure, standardized way. Think of it like a web API, but designed for LLM interactions. With this SDK you can:
Installation goes through your MCP client rather than a global install: point it at mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Python 3.10+.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by Model Context Protocol a Series of LF Projects, LLC.; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
