Tools as reported by the server

• get_content_credentials_capabilities
  Returns the free tools, byte limits, privacy behavior and interpretation boundaries before any evidence JSON is submitted.
• triage_c2pa_validation_statuses
  Classifies up to 200 C2PA validation status observations against the complete 2.4 standard catalog, flags class mismatches, separates custom codes and returns bounded remediation. Accepts codes or crJSON-style status groups; no media, URL fetching, authentication or payment.
• run_content_credentials_self_check
  Runs a deterministic, zero-input check of valid evidence, tamper detection and audit-chain verification using a synthetic fixture. No source media or caller data is used.
• verify_content_credentials_envelope
  Checks the schema, privacy boundaries and canonical SHA-256 digest of an H/M evidence envelope. It does not inspect source media or authenticate an issuer.
• verify_content_credentials_audit
  Checks report identity, source-report digest and the local custody hash chain. It does not prove operator identity, authorship or factual truth.
• create_content_credentials_policy_profile
  Creates one versioned policy profile from a fixed preset and optional rule overrides. It accepts no source media or evidence and does not authenticate the policy author.
• verify_content_credentials_policy_decision
  Checks the policy checksum, decision checksum, every per-item rule outcome and aggregate counts. It does not inspect source media, authenticate the sender or certify compliance.
