What MCP servers can actually do

5,860 tool names, each one reported by a server that answered our handshake. Registries tell you a server exists. This tells you what it exposes.

Ordered by how many separate hosts expose a tool, not how many listings. One operator running a thousand servers that all share a toolkit would otherwise fill this entire page, and did before we changed it.
