Why people use Hallucinated Citation Checker
Stop RAG hallucinations with Hallucinated Citation Exact Match Checker
With this MCP, that manual squinting disappears. You feed the quote and the source into your agent, and it immediately tells you if the citation is a perfect match or a total fabrication. You get the exact location of any errors, turning a guessing game into a precise engineering task.
What Vinkius changes
You get mathematical proof of whether a citation is real or a hallucination.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about Hallucinated Citation Checker.
The practical details behind the request, access and result.
How does the Hallucinated Citation Exact Match Checker prevent AI errors?
It uses deterministic character-level comparisons to check if a quote is an exact match to the source, rather than relying on the AI's own probabilistic guesses.
Can I use this Hallucinated Citation Exact Match Checker to find where a quote is wrong?
Yes. You can use it to find the specific character offsets where a generated quote deviates from the original source text.
Will this work with my existing RAG setup?
Yes, as long as you are using an MCP-compatible client like Claude, Cursor, or Windsurf, you can connect this to your RAG workflow immediately.
What is the difference between a partial match and a hallucination?
A partial match means the quote is similar but has deviations, while a hallucination means the text is not present in the source at all.
Is the Hallucinated Citation Exact Match Checker useful for automated testing?
Absolutely. It's designed for developers who need to programmatically verify the factual integrity of agent outputs during testing or in production.
How does the capability detect hallucinations?
The capability uses Levenshtein distance and longest common substring algorithms to calculate a hallucination score based on character deviation from the ground truth.
Can I see exactly where a quote is wrong?
Yes, by using analyze_mismatch_locations, you receive a list of character offsets indicating exactly where the generated text diverges from the source.
What is a 'Valid' citation according to this capability?
A citation is rated as 'Valid' when the verify_quote_integrity capability returns a 100% verbatim match.
