MCP Server Watch

Know when a server you installed changes its tools.

2,719

MCP servers changed their tools in the last 14 days with no version bump — 87% of 3,140 recorded changes across 727 servers.

A versioned change is the maintainer telling you. A silent one is not. If one of these is in your config, you are running tools you never reviewed.

From a dated record of 39,384 observations across 2,830 servers. Observation, not accusation — unversioned iteration is normal and often deliberate.

What this is

Anyone can tell you an MCP server's rating today. This tells you how its tool surface has actually changed over time — built from a dated record of real observations that cannot be reconstructed after the fact.
