Public MCP server monitoring
Toolpin catalogs every server in the official MCP registry, probes the reachable ones daily, and pins a cryptographic hash of each tool definition, so when a server you depend on silently changes what its tools claim to do, it shows here first.
Looking for a capability rather than a name? Search the tool index by what you need done.
