This MCP server provides precision tools for verifying the factual integrity of LLM-generated citations. By performing deterministic character-level comparisons, it identifies exactly where a generated quote deviates from the provided source text. Use verify_quote_integrity to calculate match percentages and hallucination scores, analyze_mismatch_locations to find specific character offsets of errors, and calculate_citation_validity to receive categorical reliability ratings like 'Valid' or 'Hallucinated'. It is an essential bridge for developers building high-precision RAG systems that require mathematical certainty in citation accuracy.

Verify if this quote is accurate: 'The sky is blue' from the source 'The sky is very blue.'

The quote is a Partial match. The generated text deviates from the source text.

Check the integrity of the quote 'The sun is hot' against the source 'The sun is hot.'

The quote is a Verbatim match with 100% integrity.

Is the citation 'The moon is cheese' valid for the source 'The moon is made of rock'?

The citation is Hallucinated.

The tool uses Levenshtein distance and longest common substring algorithms to calculate a hallucination score based on character deviation from the ground truth.

An AI dumped 80,000 tokens into a prompt — 64,000 of them unreferenced noise. It said 'best practice' to justify the structure and 'looks good' to measure quality. That is not context engineering — that is a copy-paste pipeline. This tool forces five context axes: relevance auditing, priority structuring, token budgeting, evidence grounding, and quality measurement.
