Audit Ledger MCP Server

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: AUDIT_API_URL (Your deployed audit-ledger API endpoint (e.g. https://<api-id>.execute-api.<region>.amazonaws.com/prod). Leave unset to run in sandbox mode against the public shared tenant.), AUDIT_WRITE_KEY (Tenant write key for your deployed ledger. Required if AUDIT_API_URL is set and you want to call record_decision.), AUDIT_READ_KEY (Tenant read key for your deployed ledger. Required if AUDIT_API_URL is set and you want to call verify_decision or list_decisions.), AUDIT_TIMEOUT_MS (HTTP timeout in milliseconds. Defaults to 5000.), AUDIT_RETRY_ATTEMPTS (Number of retry attempts on transient failures. Defaults to 3.), AUDIT_HMAC_KEY (Tenant secret used to HMAC-SHA256 PII and prompts locally before sending. Generate once per tenant (e.g. node -e "console.log(require('crypto').randomBytes(32).toString('hex'))") and keep it in your environment. The key never leaves your process. If unset, the MCP falls back to plain SHA-256 for backwards compatibility and logs a one-time deprecation warning; set this to switch to keyed hashing, which regulators (ICO/EDPB) expect for pseudonymisation.). The author declared them in the registry entry; get the values from the project itself.
