Tools

(9)
  • marketnow_verify_trust

    Verify any AI agent credential (ATC v3, JWT/OAuth, W3C VC, MCP Card, A2A, EAT-AI, ZTA, SPIFFE SVID, X.509) through the UTA 12-stage credential-verification pipeline (PARSE→DECISION — distinct from Sentinel's 12 skill-audit stages). Returns validity, format, trust score, and issues.

  • marketnow_translate_credential

    Translate a credential between the 9 adapter formats (ATC, JWT/OAuth, W3C VC, A2A, EAT-AI, ZTA, MCP Card, SPIFFE, X.509). Lossless conversion through Universal Trust Schema (UTS). See /api/trust?action=formats.

  • marketnow_list_formats

    List all 9 supported credential adapter formats (ATC, EAT-AI, ZTA, A2A, MCP Card, W3C VC, OAuth, SPIFFE, X.509) with their algorithms and status.

  • marketnow_get_pipeline

    Get the 12-stage credential-verification pipeline details (PARSE→DECISION).

  • marketnow_check_domain

    Check if a domain is suspicious (scam checker). Returns risk score and reasons.

  • marketnow_search_skills

    Search the MarketNow registry of indexed MCP servers (68k+ across GitHub, npm and PyPI, security-first scored).

  • marketnow_check_revocation

    Check the revocation status of an Agent Trust Card (card_id) or CA key (kid) against the signed MarketNow Revocation Registry (MNR-CRL-1.0) + live ledger. Returns VALID/EXPIRED/REVOKED/SUPERSEDED/UNKNOWN with PERMIT/DENY recommendation. Fail-closed: unknown subjects answer UNKNOWN+DENY. The signed CRL layer is independently verifiable via Ed25519 (RFC 8785 JCS).

  • marketnow_fingerprint_tool

    Cryptographically fingerprint MCP tool definitions (OWASP MCP Cheat Sheet: 'verify tool descriptions haven't changed'). Computes RFC 8785 JCS + sha256 per tool plus a manifest fingerprint for the whole tools/list surface. Pass a previous manifest in 'pinned' to get a drift report (added/removed/changed) — the core defense against tool poisoning and rug-pull redefinitions.

  • marketnow_submit_skill

    Publish a skill to the MarketNow catalog (the write side). The package is validated and Sentinel-scanned (injection patterns, embedded secrets, dangerous APIs, suspicious URLs, typosquat, dedup against the 68k+ catalog) AND its claims are verified live: repo_url must exist (HTTP 200), install must reference a real package on npm/PyPI/crates/Docker Hub. False claims are rejected (422). Accepted skills with real substance (files/code/verifiable repo) are stored in the public auditable queue as cer
