MCP Server List
Every MCP server in the official registry that has something to show: 34 729 in total, of which 14 744 answered our last handshake and 6 767 are listed as active but do not respond. Sorted by uptime, real installs and the number of tools each one exposes — not by date added.
New to this? What an MCP server is, and what all 34 729 of them expose — written from our own handshakes, not from the specification.
