The quiet accident
Agent incidents are rarely a model "going rogue." The boring pattern: an agent holds an API key with admin scope because that was the default when someone created it. When a prompt injection or a buggy loop hits, that key turns a small mistake into a full-account incident.
Audit from descriptions — never from the keys themselves
You don't need to (and shouldn't) paste real keys anywhere. Audit the permission descriptions:
- List every key your agents can reach: name, service, scopes, expiry.
- Flag admin / write-all scopes — an agent that reads data rarely needs write; one that writes rarely needs delete.
- Flag keys with no expiry and no rotation date.
- One key per agent, per service. A shared "god key" makes revocation impossible without downtime.
Rule of thumb: if revoking a key would break three unrelated things, the key is doing too much.
Automate the boring part
The free MCP server safe-agent-mcp includes audit_api_keys: you pass permission descriptions (never key values) and it flags over-privileged scopes and missing rotation. It also checks idempotency patterns in your agent code and explains six guard patterns (idempotency key, approval gate, outbox, key inventory, circuit breaker, signed approval link).
