MCP Canary

Recent MCP tool changes

A tool added or removed, or an argument, type, or schema changed, seen in the tool list of a public MCP server. Description edits do not count. Servers that need sign-in do not show their tools, so only open servers appear here.

Your agents depend on an MCP server's tools? A monitor alerts you on a tool change: see the docs. Also: MCP servers recently down.
