Tools & capabilities

Accord Trace tools 9

  • accord_trace_create_proofCreate an AccordTrace hash-bound service record. If issuer signing is configured, the proof also carries an Ed25519 issuer signature. Submitted content is not stored.
  • accord_trace_verifyVerify an AccordTrace recorded proof, optionally compare supplied data/hash, and verify an issuer signature when one is present.
  • accord_trace_get_proofRetrieve public non-secret AccordTrace proof metadata by proof ID.
  • accord_trace_hashCompute AccordTrace canonical SHA-256 for JSON-compatible data without creating a proof.
  • accord_trace_network_capabilitiesRead the live one-level AccordTrace Agent Affiliate Network policy, economics, anti-downline rules and payout activation status. Read-only; it does not enroll or attribute an agent.
  • accord_trace_network_statsRead aggregate live affiliate-network states, distinguishing generated invitations, attributions, qualified direct sales, earned commissions and paid commissions.
  • accord_trace_passport_product_capabilitiesRead the live Agent Passport Certificate product price and commercial readiness gates. Read-only; it never initiates checkout.
  • accord_trace_wallet_capabilitiesRead machine-facing Agent Wallet feature gates, Ed25519 signing contract, funded-balance policy, USDC representation and explicit no-credit/no-lending boundary. Read-only; it never creates a wallet or moves funds.
  • accord_trace_resolve_referralResolve a direct AccordTrace referral code to its active public referral record and disclosure without reserving attribution or creating a sale.

PDF Verify (PDF Agent Stack) tools 7

  • verify_signaturesCryptographic verification, trust chain evaluation against trust anchors, revocation checking (embedded OCSP/CRL or online), RFC 3161 timestamp verification
  • verify_integrityTamper detection: incremental updates, changes after signing, **DocMDP certification violations assessed per P value** (below), and an object-level diff of the revision chain (which objects each update added, rewrote or freed). Incremental updates are legal, so the diff says what to review — no ver…
  • detect_pades_levelPAdES baseline level (B-B / B-T / B-LT / B-LTA) with content-validated LTV data
  • identify_conformanceDeclared PDF/A / PDF/UA conformance from XMP metadata
  • validate_conformancePDF/A (ISO 19005) and PDF/UA (ISO 14289) validation: veraPDF when installed, built-in rule subset otherwise
  • validate_clausesConstraints mapped from ISO 32000-1/-2 clauses — the specification body itself, which the PDF/A and PDF/UA profiles do not cover
  • evaluate_policyDeterministic 4-value trust verdict (trust_and_use / use_with_caution / human_review_required / reject) from a fixed rule table over the verification facts, with domain profiles (contract, financial, legal, medical, government). The judge is code; the narrative is the LLM

Frequently asked questions

Accord Trace is categorized under Cryptography and uses a remote HTTP/SSE transport. PDF Verify (PDF Agent Stack) belongs to Cryptography and uses a local stdio subprocess. Pick Accord Trace for cryptography work and PDF Verify (PDF Agent Stack) for cryptography.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Accord Trace has no declared pricing — check the project's own site. PDF Verify (PDF Agent Stack) has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add accord-trace and pdf-verify-pdf-agent-stack as separate keys in the same mcpServers object, and your assistant will call tools from either one.
