How does this MCP detect hallucinations?

It uses deterministic character-level comparisons to see if the generated text matches the source text exactly.

Which AI clients can I use with this MCP?

You can use this with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

Can I find exactly where a quote is wrong?

Yes, the analyze_mismatch_locations capability identifies the specific character offsets where the text deviates.

Does this work for RAG systems?

Yes, it is specifically designed to provide mathematical certainty for citations in RAG-based workflows.

What kind of reliability ratings do I get?

The calculate_citation_validity capability provides categorical ratings like Valid or Hallucinated.

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.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Hallucinated Citation Checker.

01
Analyze mismatch locations
This capability finds the exact character offsets where the AI's text deviates from your source data.
02
Calculate citation validity
This capability provides a categorical reliability rating, such as Valid or Hallucinated, based on content and placement.
03
Verify quote integrity
This capability determines if a specific quote is a faithful representation of the original source text.

Real work

What teams actually run

RAG Pipeline Validation

Verify that your retrieval-augmented generation is pulling exact quotes from your documents.

Hallucination Detection

Catch instances where an agent fabricates information that doesn't exist in the context.

Automated Fact Checking

Run automated checks on large batches of AI-generated citations to ensure accuracy.

Citation Auditing

Audit the reliability of an AI's output by checking its placement and content against the source.

One connector, every AI

Hallucinated Citation Checker works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Hallucinated Citation Checker to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Hallucinated Citation Checker, so you can see the experience inside your AI.

It does not authenticate your account with Hallucinated Citation Checker. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
