thoughtproof/thoughtproof-mcp
📇 ☁️ - Adversarial multi-model reasoning verification for AI agents before trades execute. Claude, Grok, and DeepSeek challenge each decision — returns ALLOW or HOLD with JWKS-signed attestation. x402-gated on Base (USDC). Part of the 4-issuer Combined Attestation Standard with InsumerAPI, RNWY, and Maiat.

Documentation Overview
thoughtproof-mcp
MCP server for ThoughtProof — verify AI reasoning with adversarial multi-model consensus.
Multiple independent reasoning models (SERV Reasoning panel) evaluate every claim. A dedicated red-team model critiques their verdicts. A synthesizer weighs everything and returns ALLOW, BLOCK, or UNCERTAIN with confidence score and objections.
Quick Start

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

Works with Claude Desktop, Cursor, Windsurf, Cline, and any MCP-compatible client.
Tools
verify_claim
Verify any claim or AI-generated reasoning before acting on it.
| Parameter | Type | Default | Description |
|---|---|---|---|
claim | string | (required) | The text to verify |
stakeLevel | low / medium / high / critical | medium | Risk level — higher stakes trigger deeper verification |
domain | financial / medical / legal / code / general | general | Domain context for specialized verification |
speed | fast / standard / deep | standard | Verification depth |
check_agent_score
Look up an agent's composite trust score on the ERC-8004 registry.
| Parameter | Type | Description |
|---|---|---|
agentId | string | Agent ID to look up |
domain | string | Optional domain filter |
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

Pricing
| Speed | Models | Cost per verification |
|---|---|---|
| fast | 2 | $0.008 |
| standard | 4 | $0.02 |
| deep | 5+ | $0.08 |
Payment: API key (operator account) or x402 micropayment (USDC on Base).
API Key
Get an operator API key at thoughtproof.ai. Without a key, verifications use x402 micropayments automatically.
Configuration
