Agent Audit Mcp
Gives Claude six tools to write, search, and verify a local SHA-256 hash chain for agent events. You can log 16 event types (payments, tasks, disputes, identity checks, messages), retrieve full histories per agent, search by severity or date range, and run integrity checks that show exactly which link broke. Every event cryptographically includes the previous hash, so tampering is detectable. Data lives in a local JSON file at ~/.agentaudit/chain.json with atomic writes to prevent corruption. Reach for this when you need an immutable audit trail for multi-agent systems or compliance logging without sending data off-machine. Requires a $19/month subscription.

AgentAudit MCP
Your agent now has an immutable, tamper-evident log of every action it takes — each event cryptographically linked to the previous one so any modification breaks the chain and is immediately detectable.
What your agent can do
- Log any of 16 event types (payments, tasks, disputes, identity checks, messages) with a SHA-256 hash that includes the previous event's hash
- Retrieve the full history of any agent by ID — every action, in order, with timestamps
- Search across the audit trail by agent, event type, severity level, or date range
- Verify chain integrity between any two events and get a per-event pass/fail breakdown showing exactly which link was tampered
- Track five severity levels —
info,notice,warning,error,critical— for compliance triage - Get statistics across the entire audit trail: events by type, by severity, and most active agents
Installation
Requires: Python 3.10+, mcp and fastmcp packages.
