[gotcha] Missing telemetry makes MCP attacks invisible after they happen

Log every tool call with full arguments, server identity, tool description version/hash, user/session attribution, and model reasoning; ship logs to a tamper-resistant store; alert on unusual parameter values, cross-server call sequences, and description changes.

Journey Context:
Tool poisoning and shadowing succeed because the user interface shows only sanitized summaries. If the logs are equally thin, incident response cannot determine what was exfiltrated or when. Audit is not a compliance checkbox here; it is the only way to detect a rug pull or a cross-server parameter manipulation after the fact. Immutable, argument-level telemetry is the difference between a contained incident and an undetected breach.
