Reading One MCP Exchange End to End
A production incident does not announce which MCPA domain it belongs to. It hands you a transcript, and reading that transcript correctly, stage by stage, is the whole skill this certification tests. Assemble one 2026-07-28 exchange that carries discovery with cache hints, a schema check, an MRTR consent round trip, a task, progress notifications, an OAuth audience check, and a hash chained audit log, and say what each stage defends against. Tell a protocol error, a tool execution error, and a missing capability error apart on sight, and name the correct JSON-RPC code for each. Trace one W3C trace id across every hop of a multi step exchange, including the single call that crosses onto HTTP and behind OAuth. Verify a hash chained audit log and explain precisely what tampering with one entry does to every entry recorded after it. Use the readiness checklist in outputs/ to confirm, objective by objective, that every domain this exam weighs maps to something concrete you did in this lesson's transcript. An on call engineer opens a console and reads two lines that do not match: a ticket claims checkout-api was restarted in production, and the incident channel says it was not. Nothing about that discrepancy announces itself as "an MRTR question" or "a Security and Governance question." Untangling it means reading one transcript…
