Eleata Verify Mcp

What is Eleata Verify Mcp?

Eleata Verify Mcp is a grounding and hallucination guardrail for AI agents. It takes a claim and supporting evidence, then returns a natural-language inference verdict (Supports, Refutes, Not Enough Evidence) with a confidence score and an abstained flag for low-confidence cases. It wraps the hosted eleata Claim Verifier API.

How to use Eleata Verify Mcp?

Install via npx -y eleata-verify-mcp and set the EVERIFY_API_KEY environment variable (get a key at eleata.io). Configure in your MCP client as an mcpServers entry. Invoke one of three tools: verify_claim(claim, evidence), check_groundedness(answer, context), or verify_strict(claim, evidence) for a higher abstention threshold.

Use cases of Eleata Verify Mcp

• Fact-check a claim against source evidence before an agent trusts it

FAQ from Eleata Verify Mcp

How does Eleata Verify Mcp differ from a simple keyword match?

It uses a multilingual natural-language inference model (mDeBERTa-v3-mnli-xnli) to understand whether the evidence logically supports, refutes, or is insufficient for the claim — not just keyword overlap.

What are the runtime dependencies?

The server runs via npx (Node.js). An API key is required, obtainable from eleata.io (paid channel). No local model downloads; all inference happens on the hosted API.

Where does my data go?

The claim and evidence you send are transmitted to the hosted eleata API. See eleata’s privacy policy at https://eleata.io/privacy/ for details.

How are authentication and transport handled?

For the direct channel, the API key is sent as an Authorization: Bearer header. For the RapidAPI channel, set EVERIFY_RAPIDAPI=1 and EVERIFY_API_BASE to the RapidAPI host; the key is then sent as X-RapidAPI-Key.

What limits or caveats should I know about?

Confidence on public channels is uncalibrated – it is not a probability. Always rely on the verdict and the abstained flag, not the numeric confidence. Treat abstained=true or any verdict other than “Supported” as “do not rely”.
