trooth_ai_data_use_disclosures

Read what one company on the Trooth Network has declared about AI and customer data (whether it trains models on customer data, whether AI is in the product, which approaches), named by its domain or its Trooth slug, matched exactly. Each row is the company's own declaration and is labeled so, with whether Trooth observed a supporting policy clause: not observed means Trooth has not read one, never that the company does not train on customer data. Read only.

trooth_ask

Answer a question about Trooth itself (what the Trooth Network is, what one company record carries, pricing, how witnessing works) from Trooth's fixed, curated knowledge base; takes one question of at most 500 characters. Makes no outside request. A question the knowledge base does not cover returns out_of_scope; for a company's record use trooth_public_trust_profile.

trooth_company_changes

List how one company's published record changed: give its domain or slug and, optionally, since (an ISO 8601 date or time). Returns record versions oldest first, each with the fact keys changed, added or removed, and per-fact edits (old value, new value, time, role) when the record carries them, with next_cursor for more.

trooth_my_company_record

Needs an OAuth access token for this server, for a person who has signed in to trooth.co (no scope is required; the public tools here need no token, and an agent key is not accepted), and takes no arguments: the workspace comes from the token's subject and never from an argument. Reads the company record of the Trooth workspace the signed-in person belongs to and returns its name, its slug and the address of its public page. Read only.

trooth_outside_in_read

Fetch https://<domain>/ and /.well-known/security.txt once, when called, from Trooth's server and report whether HTTPS answered, which of five response headers (HSTS, CSP, nosniff, frame protection, referrer policy) are present, and whether security.txt is published, absent or unread. IP literals and names resolving to private, loopback or link-local addresses are refused; redirects are reported, not followed; each request stops after 4 seconds. Observations, not witnessed evidence, not a grade.

trooth_profile_checklist

Needs the workspace's agent key (permission profile:read). Takes no arguments. Lists the steps left before the workspace's Trust Profile can be published, each marked for the agent or for a person, with state done, todo or unknown and how to do it. A person's step carries action_url: give that address to the person in one sentence and carry on with your own steps. Read only.

trooth_profile_get

Needs the workspace's agent key (header Authorization: Bearer tra_... on this MCP connection; permission profile:read). Takes no arguments. Returns the workspace's own Trust Profile DRAFT as saved now, its revision (send it as if_match to trooth_profile_update), whether it is published, and its public address. With no key: status unauthenticated and the fix. Read only.

read-only

No arguments.

Input schema (JSON)

trooth_profile_publish

Puts the workspace's saved Trust Profile draft on its public page, which anyone can read. Needs the agent key with profile:publish. Takes no arguments. Success: status published with public_url. A first publish needs a person to prove the company's domain: the answer is then code human_action_required with an action_url to give that person; the draft stays saved. Every other refusal carries trooth.co's code and fix.

No arguments.

Input schema (JSON)

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

trooth_profile_update

Changes fields of the workspace's own Trust Profile DRAFT; the public page changes only on trooth_profile_publish. Needs the agent key with profile:write. Each change names one field by JSON Pointer (/tagline, /founders/-) with a value and its source { url, quote } from the company's own page, or state not_published with a reason. Returns each change as applied or rejected (with code and fix) and the new revision.

Argument	Type	Description
changes*	array	The changes, applied in order; a rejected change leaves the draft as it was and the ones after it still apply. Fields and their types: https://trooth.co/api/v1/profile/schema. Fields a person keeps (the page address, the theme, review marks) are rejected with code human_only.
dry_run	boolean	Optional. true checks every change and returns what would be kept, and saves nothing.
if_match	string	Optional. The revision you read with trooth_profile_get. When someone changed the draft since, nothing is saved and the answer is code revision_changed with the new revision.
idempotency_key	string	Optional. A key of your choosing for this exact set of changes. Retrying with the same key and changes returns the first answer with no second write. When omitted, one is made and returned as idempotency_key.

trooth_public_trust_profile

Read one company's published record on the Trooth Network, given its domain or Trooth slug, matched exactly, never by a similar name; a name several companies share returns their candidates, not a pick. Returns a status and a provenance label with the complete Trust Profile (detail full, the default) or a short answer (detail summary, the better first call). A record is keyed by its domain and does not by itself say which legal entity, subsidiary or product the domain belongs to. Read only.

read-only

Argument	Type	Description
detail	string	full (default): the complete profile, section by section. summary: the short answer, the contract summary members and where the record is; ask for it first.

sections	string	Optional. Comma-separated section names to return, from: overview, identity, history, funding, product, pricing, stack, security, privacy, ai, hosting, infrastructure, procurement, relationships, proof, people, documents, evidence, cards, faq. Omit for every section.

  }
}

trooth_resolve_company

Find the published Trooth Network record for a company given a domain, web address, Trooth slug or name; a company-register identifier, Crunchbase address or Wikidata ID is accepted and answered not_found, because Trooth keeps no lookup by them. Returns the record ID, its canonical https address and why it matched, or every candidate with why each matched (status ambiguous, none chosen), or not_found. Read only.

read-only

Argument	Type	Description
kind	string	Optional. What the identifier is; read from its form when omitted. A register identifier is read as a name unless kind says otherwise.
identifier*	string	A domain, web address, Trooth slug, legal or trading name, company-register identifier, Crunchbase address or Wikidata ID

Returns up to 10 entries per page in slug order with next_cursor for the next page (the first 100 matches can be paged), each with its name and tagline in the company's own words, whether Trooth witnessed it, and the identifier that reads its record with trooth_public_trust_profile. Read only.

Argument	Type	Description
query*	string	Words to match: a company name, a domain, a category such as payroll or observability

trooth_verify

Check the two signatures on a Trust Ledger Token (tlt2. or tlt. form, or its JTI) against Trooth's own token ledger. A Trust Ledger Token is a signed token a company issues through Trooth about its own declared claims: the company signs the claims and Trooth signs the event of issuing it. Returns valid, invalid (a signature does not check out), expired or revoked, or unclaimed when no token matches; Trooth's signature covers the signing event, not the claim bytes and not the truth of the claims.
