Model Context Protocol server for the Kakunin AI agent compliance API. Lets AI agents self-verify scope, check their own risk score, and log behavioral events — all from within Claude, Cursor, or any MCP-compatible runtime.

Tools

verify_agent_scope

Check whether this agent is authorised to perform an action before executing it. Verifies the active X.509 certificate, permitted_actions scope, financial limits, and revocation status.

{
  "action": "initiate EUR/USD trade on euronext for 50000 USD",
  "venue": "euronext",
  "amount_usd": 50000
}

Returns { allowed: true|false, reason, certificate_status, permitted_actions }.

check_risk_score

Retrieve the agent's rolling 30-day risk score, band (low/medium/high), drift trend, and actionable guidance. No input required.

audit_log_append

Append a behavioral event to the agent's immutable audit log. Returns risk score + transaction ID. Events scoring ≥ 0.85 auto-trigger a certificate revocation check.

{
  "action_type": "transaction_initiated",
  "details": { "amount_usd": 50000, "venue": "NYSE" }
}
