    How to connect

    How to connect trust-tools to Claude

    The server address to paste into Claude settings:

    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    Raw names from tools/list. Only developers need these.

    scan_trustRun Obelisk's public trust scan on an https URL — TLS and security-header posture, scored as an Obelisk Rating. Read-only, SSRF-guarded.
    verify_tokenVerify 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.
    get_org_ratingRead the public Obelisk Rating (0-100 score, trust band, and trend) for a registered organization by its slug.
    verify_agent_run_proofVerify the structural integrity, agent binding, delegation continuity, and commitments of an Obelisk action-scoped run proof. Does not reveal or infer raw task data.
    get_agent_proofRead 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_headRead 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.
    gate_statusRead the Gate's public liveness facts: issuer, served code revision, OIDC availability, and supported protocols. No posture internals.
    explain_ratingExplain 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.
