Audit Ledger Mcp

If you're shipping AI in healthcare, finance, or anywhere the EU AI Act or FCA model risk rules apply, this server gives you a one-line path from Claude Desktop or LangGraph to a tamper-evident audit trail. It exposes three tools: record_decision logs AI outputs with locally hashed PII, verify_decision checks integrity against S3 Object Lock storage, and list_decisions queries your tenant's history. The sandbox mode lets you test with zero config using npx, writing to a shared public ledger. For production, point it at your own deployed audit-ledger backend and get 7-year COMPLIANCE-mode retention in DynamoDB and S3. Personal data never leaves your machine unhashed, so you can log GDPR-sensitive decisions without transmitting raw PII to storage.
