Overview

Production-grade visibility into MCP traffic

Open any exchange and see headers, payloads, and timing in full detail. Follow a session across tools and widgets instead of piecing together disjointed logs. Share a link and your team jumps straight to the failing trace.

  1. 01
    All traffic captured
    Every tool call, resource read, and prompt request is recorded automatically. No instrumentation required.

  2. 02
    Drill into any exchange
    Open a trace to see the full request/response, latency breakdown, client, and session context.

  3. 03
    Share and resolve
    Copy a permalink to any trace. Your team opens the exact same view, with no repro steps needed.
