Why it matters

MCP (Model Context Protocol) is Anthropic's open standard for exposing tools, data, and prompts to LLM agents. The server ecosystem exploded in 2025-2026; picking the right servers is now as important as picking the right model.

What's in here

Covers official reference servers (filesystem, github, postgres, slack), registries + directories (Smithery, PulseMCP), server frameworks (fastmcp, mcp-python-sdk), and vertical servers for databases, browsers, cloud APIs, and enterprise systems.

How to pick

Pick official reference servers for common integrations (git, filesystem, sql). Pick Smithery or PulseMCP to browse and install. Pick fastmcp when writing your own server. For internal APIs, ship an MCP wrapper rather than raw REST — every Claude-native workflow gets it for free.
