Claude now traces every MCP connector call. Your server shows up in someone's dashboard.
By Lior AharonovFounder, 7IT Solutions ·
Anthropic put OpenTelemetry traces on the Claude Platform into public beta on 14 October 2026. Its docs say the API adds a tool span for each use of a server tool or an MCP connector tool that the API runs. The default Metadata only mode carries identifiers, timing, status, token counts and the names of MCP servers; Full content adds prompts and responses.
Your server's name, latency and status now sit next to every model call in the customer's own Datadog or Grafana view. A slow call is no longer a vague feeling. It is a bar on their chart, with your name on it.
Give your MCP server a clear, stable name, and check your own latency and error rate before a customer's trace shows it to them.
Your customers just got a stopwatch. I'd rather know my numbers before they read them to me.
