MCP tools · 10 exposed · ~1,015 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
agent_enrollment_guide ~72

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

explain_rating ~138

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.

NameTypeReqDescription
narrateboolean–S283 — also return `narrative`, a one-sentence model-written reading of the band (deterministic fields are always present).
ratingnumberyesA 0-100 Obelisk Rating, e.g. from scan_trust or get_org_rating.

No output schema declared.

No examples provided.

gate_status ~36

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

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_agent_proof ~67

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.

NameTypeReqDescription
proof_idstringyesThe opaque id from an /agent/<proof_id> link.

No output schema declared.

No examples provided.

get_org_rating ~52

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

NameTypeReqDescription
orgstringyesThe organization slug, e.g. acme.

No output schema declared.

No examples provided.

pin_tool_manifest ~164

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.

NameTypeReqDescription
expected––Optional: the catalogueDigest string from an earlier pin, or an object of { toolName: digest } (optionally with catalogue).
toolsarrayyesThe tools array exactly as the server's tools/list returned it.

No output schema declared.

No examples provided.

scan_trust ~65

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

NameTypeReqDescription
urlstringyesThe https URL to scan, e.g. https://example.com

No output schema declared.

No examples provided.

transparency_head ~87

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

verify_agent_run_proof ~266

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.

NameTypeReqDescription
expected_agent_idstring–Optional expected agt_ subject.
expected_audiencestring–Optional: require the run token's audience to equal this value.
run_proofobject–An obelisk-agent-run-proof-v2 envelope (a legacy v1 envelope is accepted and flagged unsalted-v1). Alone it is checked for consistency only; next to run_proof_token it must equal the signed copy.
run_proof_tokenstring–The run_proof_token returned by POST /api/agent-proof/run. The only input that can verify.

No output schema declared.

No examples provided.

verify_token ~68

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.

NameTypeReqDescription
tokenstringyesA compact-serialized JWT issued by Obelisk (id_token or access token).

No output schema declared.

No examples provided.
