Tools reference＃

The kluster.ai's MCP server provides two verification tools that work identically whether deployed self-hosted or via Cloud MCP. These tools enable real-time reliability verification directly within your AI assistant conversations.

This page documents the tool parameters and response formats you'll see when using these tools in any MCP-compatible client.

Tool overview＃

The following tools are available through the kluster.ai MCP server:

Tool Purpose Best For
verify Verify standalone claims General statements, trivia, current events, news
verify_document Verify claims about documents Quotes, data extraction, RAG hallucination checking

Verify＃

The verify tool allows you to check any statement against reliable online sources.

Parameters:

Parameter Type Required Description
claim string Yes The statement to verify
returnSearchResults boolean No Include source citations (default: true)

Verify document＃

The verify document tool checks that claims accurately reflect the content of the uploaded document.

Parameters:

Parameter Type Required Description
claim string Yes Your interpretation of the document
documentContent string Yes Full document text (auto-provided by MCP client)
returnSearchResults boolean No Include external sources (default: true)

Response fields＃

All verification tools return the same response structure:

  • claim: The verified claim.
  • is_accurate: Boolean indicating if claim is accurate.
  • explanation: Detailed reasoning for the verdict.
  • confidence: Token usage statistics.
  • search_results: Source citations (if requested).

An example can be seen below:

  "is_accurate": false,
  "explanation": "The claim is incorrect. Section 4.2 explicitly requires on-site work minimum 3 days per week and residence within 50 miles of headquarters.",
  "confidence": {
