## Tools
- submit_incident - Submit an AI incident for deterministic causal liability attribution. Returns a signed CausalCertificate, per-agent liability allocation, evidence-chain completeness, regulatory mapping, and (where keys are configured) a Bitcoin-anchored proof. Cost: 50 credits. Three guardrails apply: PII scan, deterministic-only acknowledgement, and minimum evidence. Endpoint: https://causallayer-mcp-demo.zykm9qkk7j.workers.dev/mcp
- verify_certificate - Independently verify a CausalCertificate end-to-end (signature, Merkle integrity, issuer status against the registry). Cost: 1 credit. In production env, certificates from non-active issuers are rejected. Endpoint: https://causallayer-mcp-demo.zykm9qkk7j.workers.dev/mcp
- get_anchor_status - Return the index of all CausalLayer Tessera anchor batches, or one batch's full JSON (signed Merkle root, leaves, OpenTimestamps proof reference). FREE. Endpoint: https://causallayer-mcp-demo.zykm9qkk7j.workers.dev/mcp
- query_issuer_registry - Return the CausalLayer issuer registry, or one issuer record. The registry lists all trusted public-key fingerprints, key algorithms, validity windows, and the anchor-log repo for each active issuer. FREE — no API key required. Endpoint: https://causallayer-mcp-demo.zykm9qkk7j.workers.dev/mcp
