    "thoughtproof": {
      "command": "npx",
      "args": ["-y", "thoughtproof-mcp"],
      "env": {
        "THOUGHTPROOF_API_KEY": "tp_op_your_key_here"
      }
    }
  }
}

Cursor

Add to Cursor's MCP settings:

{
  "thoughtproof": {
    "command": "npx",
    "args": ["-y", "thoughtproof-mcp"],
    "env": {
      "THOUGHTPROOF_API_KEY": "tp_op_your_key_here"
    }
  }
}

Windsurf / Cline

Same pattern — point to npx thoughtproof-mcp with the env var.

Example

In Claude Desktop or Cursor, just ask:

"Verify the claim: GPT-5 achieves 95% accuracy on MMLU-Pro"

The tool returns:

⚠️ UNCERTAIN (42% confidence)

Claim: "GPT-5 achieves 95% accuracy on MMLU-Pro"

Objections:
- Insufficient public benchmark data to confirm
- Historical accuracy claims have been overstated
- MMLU-Pro methodology has known ceiling effects
