October 2026

What changed in the definitions of the MCP servers this log tracks, counted from the signed public log on 1 November 2026. Every number here can be checked: the report as JSON, and the log it was counted from.

162servers changed their tool definitions

535servers tracked by the end of the month

3574tools changed in the schema only, with the description untouched

281servers recorded for the first time

Coverage

No crawl ran from 4 September 2026 to 5 October 2026: the scheduled crawl was paused; see CHANGELOG 0.1.4. A change first seen after that gap happened at some point inside it.

Between the last look before a change and the first look that saw it: 1.2 days at the median, 56.1 at most.

What kinds of change

Servers with at least one change of each kind. A server can count under several. The labels are mechanical: each means the new definitions match a pattern the old ones did not, not that anyone did anything wrong, so they are totals and are never shown against a named server.

added a tool

removed a tool

added an input field

removed an input field

changed the type of an input field

125

Servers that changed

Each links to that server’s full history, with every diff. Tool counts only.

How this was counted

Counted from the signed public log. Check it with: npx --yes mcp-pin verify-log

A change is a new set of tool definitions recorded for a server that had one before. The log records versions, not the moment they changed: a change first seen on one day happened at some point after the last look before it.

Labels are mechanical. Each means the new text has more of a pattern than the old one (an instruction to the model, words about secrets, a link, hidden characters) or that a field or permission hint moved. They are not a judgement of any server, so they are totals here, never shown against a named server.

For 165 of these changes the log does not say what conditions the probe ran under (entries before 5 October 2026 dropped them; see the CHANGELOG). A listing can change because of the probe, missing credentials for example, rather than the server, so a large drop in tool count may not be the server's doing.
