Report #99819

[gotcha] MCP deployments often have no audit trail, making breaches invisible

Log every tools/list, tools/call, resources/read, and sampling/createMessage with request ID, arguments, and results; ship to an immutable store; alert on anomalous sequences.

Journey Context:
The protocol does not mandate logging, and most clients ship with minimal observability. Without telemetry, prompt injection, token theft, and data exfiltration leave no recoverable evidence. Teams focus on prevention and forget detection, but prevention will never be perfect for a protocol built on natural-language reasoning. Immutable, sequence-aware audit logs are the only way to investigate and respond.
