Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

MCP
MCP servers now tell you how many tools were dropped for malformed schemas.
What's wrong with this entry?
Anonymous. No account, no email.
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.
