Get started with MCP＃

Connect kluster.ai's verification tools to your AI assistant through Model Context Protocol (MCP). This guide shows you how to enable Cloud MCP and integrate it with Claude desktop for real-time claim validation directly within your conversations.

Cloud MCP provides managed verification endpoints with no infrastructure to maintain - just enable your MCP endpoint and start verifying.

Prerequisites＃

Before getting started, ensure you have:

  • A kluster.ai account: Sign up on the kluster.ai platform if you don't have one.
  • A kluster.ai API key: After signing in, go to the API Keys section and create a new key. For detailed instructions, check out the Get an API key guide.
  • Claude desktop for testing the integration.

Enable MCP＃

To enable the MCP endpoint, go to the kluster.ai platform

  1. Navigate to MCP and view your current MCP status.

  2. Click the Enable Verify MCP button to activate your endpoint.

  3. Copy your client configuration.

Endpoint enabled

Your MCP endpoint is now active. Copy your API key and save it securely.

The platform provides ready-to-use integrations examples for VSCode, Cursor, Claude code, and Claude desktop.

Configure Claude desktop＃

Edit your Claude desktop configuration file:

~/Library/Application Support/Claude/claude_desktop_config.json

%APPDATA%/Claude/claude_desktop_config.json

Add the MCP server configuration:

{
  "mcpServers": {
    "kluster-verify-mcp": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://api.kluster.ai/v1/mcp",
        "--header",
        "Authorization: Bearer YOUR_MCP_TOKEN"
      ]
    }
  }
}

Replace YOUR_MCP_TOKEN with your actual token or copy the snippet from the platform. Restart Claude desktop. Once Claude desktop restarts, you'll see the verification tools available under kluster-verify-mcp.

Available tools＃

Your MCP integration provides two verification tools:

  • verify: Validates claims against reliable online sources.
  • verify_document: Verifies claims about uploaded document content.

For detailed parameters and response formats, see the Tools reference.

Verify＃

Ask Claude to verify something obviously wrong:

"Use the verify tool and tell me if The Eiffel Tower is located in Rome"

Claude will automatically use the verify tool and provide:

  • Verification result: Whether the claim is accurate.
  • Detailed explanation: Why it's wrong with supporting reasoning.
  • Source citations: Search results used for verification.

Verify documents＃

Perfect for detecting hallucinations or false claims about documents. Upload any document to Claude, then ask:

"This document says X. Use the verify_document tool and check if that's accurate"

Claude will use the verify_document tool to verify your claim against the actual document content.

Alternative setup options＃

  • Other clients: Want to use VS Code, Cursor, or Claude Code? Check the Client integrations guide for configuration examples.

  • Self-hosted: Prefer to run MCP locally? Set up the self-hosted MCP server for local development with full control.

  • API activation: Enable MCP using API calls with the MCP API usage guide.
