Tool of Truth

每一次工具调用，皆有实证。

面向 AI 代理工具使用的验证哨兵。一个 MITM 代理，拦截所有 MCP 工具调用，检测伪造、追踪成本、验证结果，并推断用户满意度。

快速开始

1. 安装

npm install -g tooloftruth-mcp

2. 连接（选项 A：直接）

// Your agent's MCP config
{
  "tooloftruth": {
    "command": "tooloftruth-mcp"
  }
}

3. 连接（选项 B：代理 — MITM 模式）

// Your agent's MCP config
{
  "tooloftruth": {
    "command": "tooloftruth-mcp"
  }
}
// ~/.tooloftruth/proxy.json
{
  "servers": {
    "firecrawl": { "command": "npx", "args": ["firecrawl-mcp"] },
    "github": { "command": "npx", "args": ["@modelcontextprotocol/server-github"] }
  }
}

4. 使用

You: Did you actually use firecrawl?
Agent: [calls tooloftruth_verify]
Agent: VERIFIED — firecrawl was called at 10:30:02, trust score 98/100, cost $0.03

You: How much did I spend on tools today?
Agent: [calls tooloftruth_cost]
Agent: Total: $0.47 across 12 tool calls

You: Was that result what I asked for?
Agent: [calls tooloftruth_outcome]
Agent: ALIGNED — tool result matches your request

You: That's wrong, try again
Agent: [calls tooloftruth_satisfaction]
Agent: User appears dissatisfied — result may be wrong

CLI

# Intercept and monitor non-MCP commands
tooloftruth -- gh api repos/user/repo

# One-shot status report (daemon health, receipts, cost, top tools)
tooloftruth status

守护进程

一个 launchd 守护进程监视 .tooloftruth/receipts/，聚合每日统计信息，并在检测到伪造时发出警报。

# Install the daemon (macOS)
launchctl load ~/Library/LaunchAgents/com.tooloftruth.daemon.plist

统计信息写入 .tooloftruth/stats/YYYY-MM-DD.json。

真相扫描

tooloftruth_truth_scan 对声明进行真实的网络验证：Bing 搜索（curl）→ crawl4ai 抓取 → 证据提取 → 判定。

MITM 代理的工作原理

Agent ←→ Tool of Truth ←→ MCP Server (downstream)
              ↓
         Records everything
         Runs deep fabrication checks
         Verifies outcome alignment
         Infers satisfaction
         Generates receipts
         Returns result unchanged

存储

## Skill Manifests

Skills can attach verification manifests:

```json
{
  "skill": "last-30-days",
  "version": "2.1.0",
  "requires": {
    "github_mcp": {
      "tool": "get_repo_stats",
      "mustBeCalled": true
    }
  }
}

开发

git clone https://github.com/adigoel07/tooloftruth.git
cd tooloftruth
pnpm install
pnpm build
npx vitest run

    MCP server for verifying AI agent claims vs reality — single-transcript inline grounding-check that flags when an agent's response states facts not in the input context, when its code silently swallows exceptions and substitutes mock data, or when its multi-turn transcript contains contradictions or unverified completion claims. Sub-second, local, free, no API calls.
