πŸ“‘ Sister site: API Library β†—

πŸ”Œ MCP Directory

A map of 100+ hand-curated Model Context Protocol servers (with connect configs) plus a 18,496-server catalog from every public registry β€” what they do, what they cost, and exact configs to connect them to Claude Code, Claude Desktop, Cursor or VS Code.

MCP β‰  API. An API is a service's raw interface. An MCP server is a standard connector that wraps tools/data so any AI agent can use them β€” the agent speaks one protocol (MCP) instead of a hundred different APIs. Server code here is almost always free & open source; the tier badge rates what it costs to actually use it end-to-end, including the service behind it.
Free = works end-to-end at $0 Β· Freemium = free tier exists, real usage needs a paid plan/API key Β· Paid = needs a paid product or paid API to be useful
