What probably matters to youSection of the release
What
When an MCP server offers tools whose input schemas are malformed, you now get a line saying how many tools were excluded, instead of those tools quietly not appearing.
Details
A new per-server count message sits alongside the existing message that names the individual server and tool.
Produced from the same place that handles the server's dropped-tool notices.
Evidence
tools excluded (invalid input schema)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
