Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • assess_hallucination_riskAssess Hallucination Riskread-only

    Heuristic hallucination-RISK assessment of AI-generated text using llmverify linguistic pattern analysis (claim specificity, citations, vague language, contradictions). IMPORTANT: a high risk score means claims warrant human review — it does NOT establish that any claim is factually false, and a low score does NOT establish truth.

  • check_piiCheck for PIIread-only

    Pattern-based PII scan returning PII types, counts, and masked findings — raw sensitive values are never returned. Coverage is heuristic and NOT exhaustive: absence of findings does not prove content is PII-free.

  • check_prompt_injectionCheck Prompt Injectionread-only

    Heuristic prompt-injection indicator scan of untrusted text using llmverify pattern detection. A negative result does NOT prove the input is safe from all attacks — it means no known indicators were observed. Inspected text is never executed.

  • get_llmverify_capabilitiesGet LLMVerify Capabilitiesread-only

    Report the installed llmverify engine version, supported engines, truthful capability metadata (what each engine observes vs. does NOT establish), result schema version, adapter limits, and local state locations. Use this to discover what verification actually means here before interpreting tool results.

  • redact_piiRedact PIIread-only

    Return a PII-redacted copy of the supplied text using llmverify pattern redaction. Original matched values are never returned. Pattern coverage is not exhaustive — review output before relying on it for disclosure decisions.

  • verify_llm_contentVerify LLM Content

    Run llmverify heuristic verification on AI-generated text: hallucination-risk signals, consistency, JSON validation, and CSM6 security/PII/injection findings. Returns a structured risk assessment with explicit limitations and an honest audit persistence receipt. Results are heuristic risk SIGNALS for triage — not factual verification, safety certification, or compliance clearance.
