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＃

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

Parameters

The statement to verify.

returnSearchResults boolean

Verify document＃

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

Parameters

claim string required

The statement to verify.

documentContent string required

returnSearchResults boolean

Response fields＃

All verification tools return the same response structure:

  • claim: The verified claim.
  • is_accurate: Boolean indicating if the 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:

    "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": {
        "completion_tokens": 156,
        "prompt_tokens": 890,
        "total_tokens": 1046
    },
    "search_results": []
}
