Is obelisk-trust-tools live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is obelisk-trust-tools free to use?

Yes — the hub reached it with no key and no payment.

What tools does obelisk-trust-tools have?

10 tools: scan_trust, verify_agent_run_proof, get_agent_proof, transparency_head, pin_tool_manifest, explain_rating, agent_enrollment_guide, get_org_rating, ….

Is obelisk-trust-tools safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• scan_trust reads unknown never probed

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

• verify_agent_run_proof reads unknown never probed

  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 registry when the token was signed. A bare run_proof envelope is only checked for internal consistency and is never reported as verified, because anyone can build one. Reports the envelope's commitment scheme: a legacy v1 envelope, whose hashes are unsalted, carries the warning unsalted-v1. Does not reveal or infer raw task data.

• get_agent_proof reads unknown 20h ago

  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.

• transparency_head reads unknown never probed

  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 saved one. Same data as /.well-known/obelisk-transparency.json.

• pin_tool_manifest unknown never probed

  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 expected to detect a changed, added or removed tool. Up to 64 tools in a request body of at most 256 KB. Read-only and stateless; the injection score is one signal, not a guarantee.

• explain_rating reads unknown never probed

  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.

• agent_enrollment_guide unknown never probed

  Read how an AI agent enrolls with this Obelisk Gate: the endpoints in order, the fields each takes, which key types this deployment can prove, whether enrollment is switched on, and the current account sign-up posture an approving owner needs. Read-only; no input, no state is changed.
