What
Tool calls served by an MCP server that came from a plugin now carry plugin attribution in telemetry, at each tool result and error site. Servers you configured yourself are unaffected.
Details
Redaction allowlist gains plugin_id_hash, plugin_name_redacted and marketplace_name_redacted.
The attribution blob is attached to the tool descriptor only when the server config names a plugin source.
Evidence
pluginTelemetry, plugin_name_redacted
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
