Trust Tools MCP server

• explain_ratingFree

  Explain what an Obelisk Rating number means: its trust band, how the public scan scores, and what typically moves a score. Deterministic by default; pass narrate:true for an additional one-line model-written narrative (cached, public-scope, never required). Pure function of the number — no data is read.

• gate_statusFree

  Read the Gate's public liveness facts: issuer, served code revision, OIDC availability, and supported protocols. No posture internals.

• get_agent_proofFree

  Read an Obelisk agent's public proof vector by opaque proof id. Returns independent claims with freshness and scope; never a scalar trust score or a claim of non-humanness.

• get_org_ratingFree

  Read the public Obelisk Rating (0-100 score, trust band, and trend) for a registered organization by its slug.

• scan_trustwrite actionFree

  Run Obelisk's public trust scan on an https URL — TLS and security-header posture, scored as an Obelisk Rating. Read-only, SSRF-guarded.

• transparency_headFree

  Read the current signed transparency head of Obelisk's tamper-evident receipt ledger — pin it and compare later to prove history only extends. Same data as /.well-known/obelisk-transparency.json.

• verify_agent_run_proofwrite actionFree

  Verify the structural integrity, agent binding, delegation continuity, and commitments of an Obelisk action-scoped run proof. Does not reveal or infer raw task data.

• verify_tokenFree

  Verify that a JSON Web Token was minted by this Obelisk Gate (ES256, correct issuer) and report its type, subject, assurance, and principal. Never returns secrets.
