A remote trust registry that lets an assistant check a trust verdict (A0–A4) and retrieve signed fact passports for agents.
What you can do
Intesta is a remote MCP endpoint that provides a trust registry for agents. Its described capability is a check_trust tool returning a verdict on a scale from A0 to A4, along with signed fact passports and what the description calls honest refusals. No tool list, parameters, or response formats are documented in the supplied material.
When to use it
Consider it when an assistant needs a third-party trust signal about an agent or entity before acting, and a graded verdict with signed attestations would be useful. The supplied description does not explain the meaning of the A0–A4 levels, so evaluate that before relying on it.
Requirements
A remote streamable HTTP endpoint at No packages, environment variables, headers, or authentication are declared, so it appears to need only network access to that host.
Before you install
The server is remote, so any data sent to it leaves the user's machine and goes to a third party. No authentication is declared, which means requests may be unauthenticated or the endpoint may require credentials not documented here. The trust verdicts and signed passports are third-party claims; the supplied material gives no basis for verifying how they are produced.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.intesta%2Fregistry/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
List published entities in the Intesta registry with their trust level
(A0-A4; call get_passport for the level's meaning and proof). Returns at
most 500 entities plus the registry total — on a large registry use
search_entities(query) instead of paging through everything.
Takes no parameters.
get_passport
Full public fact passport of an entity: attested statements with
sources, plus the attestation block (what the trust level proves, how and
when it was verified).
Parametersentity_domainrequired
ask
Ask a natural-language question about an entity (max 2000 characters).
Retrieval is constrained to the entity's passport; each returned fact
carries source, attestation status and validity dates. When no matching
supported fact is selected, the tool returns an explicit refusal.
Parametersquestionrequiredentity_domainrequired
search_entities
Search published entities by name, domain or vertical (case-insensitive
LITERAL substring; wildcard characters are treated as text). Use this
instead of list_entities when the registry is large. The query must be at
least 3 characters. Returns at most `limit` matches (1-50) plus `total`,
the number of matching entities in the whole registry.
Parameterslimitqueryrequired
get_trust_ladder
Machine-readable semantics of the A0-A4 trust ladder: what exactly is
proven at every level, and how to use the registry as an agent.
Takes no parameters.
check_trust
ONE-CALL decision aid before your agent pays, shares data with, or follows
instructions from a domain — works for ANY domain, listed or not.
Returns known (is it in the registry), level A0-A4, attested (true only at
A1+: something was independently verified), verdict for the given purpose
(sufficient | insufficient | unknown) under a named policy profile,
what_is_proven, proof, facts_public, expires_at (the earliest freshness
expiry among the domain's facts — re-check after it), next_step, and the
registry signature. purpose: payment (default) | data_share | follow_instructions.
A verdict is the registry's proof measured against the profile — never a
guarantee, never financial advice.
