Pull request overview

Removes the last remaining generic capture of ErrorDetails into telemetry when tool execution returns an error result.

Changes:

  • Deletes the fallback logic that extracts the first TextContentBlock from an error CallToolResult and emits it as TagName.ErrorDetails.
  • Leaves error status reporting intact via activity?.SetStatus(ActivityStatusCode.Error).

Should the ErrorDetails be logged locally instead of a telemetry event?

Should the ErrorDetails be logged locally instead of a telemetry event?

Given we're using the SDKs under the hood for this, outside MCP specific code such as args parsing, etc, we probably should provide guidance on configuring SDK logging to capture this.
