Independent fact-checking for AI answers: a verdict and sources for every claim.

MCP Server: ai.noevant/fidenta-verify

The ai.noevant/fidenta-verify Model Context Protocol (MCP) server provides independent fact-checking for AI answers. For each claim, it returns a verdict along with sources, enabling verification of the underlying references. The server exposes 5 tools to support this workflow.

🛠️ Key Features

Independent fact-checking for AI answers
Verdict per claim
Sources provided for every claim
5 available tools

🚀 Use Cases

Verify factual claims produced by AI responses
Review the sources supporting specific statements
Produce claim-by-claim verdicts for answer auditing

⚡ Developer Benefits

Tooling to attach verdicts and sources to AI claims
Claim-level structure for verification outcomes

⚠️ Limitations

The description only specifies verdicts and sources; it does not state coverage scope, language support, or claim types.

Captured live from the server via tools/list.

verify_claims

Fact-check text against live web evidence from two independent retrievers, then have a model from a different lab audit the verdict. Returns per-claim verdicts: SUPPORTED, CONTRADICTED, UNSUPPORTED (searched and found nothing — not the same as false), or UNVERIFIABLE (opinion or prediction). Use before relying on a factual claim, or to check your own draft answer before sending it.

Parameters5

text	string	optional	The text to verify. A single claim or a full answer containing several. May also be a bare link, e.g. 'verify https://example.com/article'.
url	string	optional	A public http(s) link to an article or web page. We fetch it, extract the readable text and verify the claims in it. Use this when the user gives you a link instead of text — you do not need to fetch the page yourself. Pages behind a login or paywall cannot be read; ask for the text instead.
force	boolean	optional	Re-check even if a recent saved result exists.
max_claims	integer	optional	Hard cap on how many claims to verify, and therefore on how many credits this call can spend. Use it to bound cost on a long document.
confirm	boolean	optional	Required to proceed when the text contains more than 3 checkable claims. Call estimate_claims first, tell the user the claim count and credit cost, then call again with confirm true once they agree.

}

estimate_claims

FREE. Break text into checkable claims and report how many there are and how many credits verifying them would cost. Spends nothing and verifies nothing. Always call this before verify_claims on anything longer than a sentence or two — an article can contain 20 claims, and each claim costs one credit, so the user should see the price before agreeing to it.

Parameters2

text	string	optional	The text to break into claims. May also be a bare link.
url	string	optional	A public http(s) link to an article or web page. We fetch it, extract the readable text and verify the claims in it. Use this when the user gives you a link instead of text — you do not need to fetch the page yourself. Pages behind a login or paywall cannot be read; ask for the text instead.

    }
  }
}

top_up

Buy more verification credits without leaving the conversation. Call with confirm false (or omit it) to see the price, the card on file and the remaining monthly limit; call again with confirm true once the user has agreed. Charges the card the user already saved and authorised for in-chat top-ups — if no card is saved, or the bank requires the cardholder present, it returns a secure checkout link instead of charging.

Parameters1

confirm

boolean

optional

True only after the user has explicitly agreed to the charge. Never set this on your own initiative.
