Cierto bronze

www.cierto.tools

“Cierto answers one question about US federal contracts: should this business bid? Use find_contracts to find open SAM.gov notices, get_contract to look one up, past_awards for what the government paid before and who won. assess_contract starts a $1.50 order for the full brief against the business's profile and returns a checkout link for the person to pay; after payment, get_brief returns the brief. Every result has a summary you can say back as-is and a data object; every value in a brief carries its source and date, and could_not_confirm lists what Cierto could not check. Briefs are assessments of public records, not eligibility determinations or legal advice.

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate

Issued by Google Trust Services domain-validated

Valid until 24 Jan 2027 as of our check on 8 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.cierto.tools controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.

What kind of listing

• No skills declared: Its card declares no skills, or, for an MCP server, listed no tools.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.
