Documentation Overview
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. |

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/.
