Tools

• explain_rating ~198 tokens
  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 r
• gate_status ~64 tokens
  Read the Gate's public liveness facts: issuer, served code revision, OIDC availability, and supported protocols. No posture internals.
• get_agent_proof ~108 tokens
  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_rating ~84 tokens
  Read the public Obelisk Rating (0-100 score, trust band, and trend) for a registered organization by its slug.
• pin_tool_manifest ~254 tokens
  Pin an MCP tool manifest before an agent trusts it. Returns a SHA-256 digest per tool and for the whole catalogue (canonical JSON, every field counts), hidden-text findings (Unicode tag, bidi and zero-width characters) and an injection signal per tool. Pass the digests you stored at approval as expe
• scan_trust ~94 tokens
  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_head ~131 tokens
  Read the current signed transparency head of Obelisk's tamper-evident receipt ledger. Save headAnchorHash with anchorCount and compare later: the count must never go down, and the head at a saved count must not change. No consistency proofs are published, so this cannot show a later head extends a s
• verify_agent_run_proof ~377 tokens
  Verify an Obelisk run proof. Pass run_proof_token, the token Obelisk signs at POST /api/agent-proof/run: the tool checks Obelisk's signature against its published keys, that the named agent is active now with the same key that answered the run challenge, and which delegation hops matched the owner's
• verify_token ~110 tokens
  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.
