eleata Claim Verifier — MCP server

A grounding / hallucination guardrail for AI agents. Give it a claim and supporting evidence; it returns whether the evidence Supports / Refutes / gives Not Enough Evidence for the claim (natural-language inference), with a confidence and an abstained flag for low-confidence cases. Wraps the hosted eleata Claim Verifier.

Use it as a fact-check / RAG hallucination guard: before an agent trusts or repeats a statement, check it against its source. Treat abstained=true (or any verdict other than Supported) as "do not rely".

Tools

Tool	What it does
`verify_claim(claim, evidence)`	Is the claim supported by the evidence? Verdict + confidence + `abstained`.
`check_groundedness(answer, context)`	RAG guard: is the model's answer grounded in the retrieved context?
`verify_strict(claim, evidence)`	Same, with a higher abstention threshold — for compliance/legal where a wrong "Supported" is costly.

Setup

{
  "mcpServers": {
    "eleata-verify": {
      "command": "npx",
      "args": ["-y", "eleata-verify-mcp"],
      "env": { "EVERIFY_API_KEY": "your_key" }
    }
  }
}

Notes

Confidence is uncalibrated on the public channels (not a probability) — rely on the verdict and the abstained flag, not the raw number. The engine is a multilingual NLI model (mDeBERTa-v3-mnli-xnli). verify sends your claim + evidence to the hosted API; see https://eleata.io/privacy/.
