What
Stale MCP attribution no longer survives a conversation reset, so a later error or event is not tagged with the server and tool from a previous turn.
Details
- The query loop's tool-state object gained an
onReset hook - The hook calls a new helper that clears
activeMcpServer and activeMcpTool on the options object, guarded by try/catch - The same helper is also invoked at the start of the API loop
Evidence
activeMcpServer
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
