🛡️ ToolTrust Directory

This repo hosts tooltrust.dev — the website and pre-scanned report data. If you want to scan your own MCP servers, go to tooltrust-scanner.

A public registry of AI agent tools, continuously scanned for prompt injection, data exfiltration, and privilege escalation by ToolTrust Scanner.

🚨 Supply-Chain Incident Coverage (March 2026) ToolTrust now detects and blocks confirmed supply-chain incidents including the LiteLLM / TeamPCP compromise and the malicious axios npm publish (axios@1.14.1, axios@0.30.4). For npm-backed MCP servers, ToolTrust also scores dependency visibility, transitive lockfile evidence, lifecycle scripts, and IOC indicators such as plain-crypto-js.

🤖 AI Agent Integration

Let your AI agent scan its own tools. Add ToolTrust as an MCP server in your .mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "tooltrust": {
      "command": "npx",
      "args": ["-y", "tooltrust-mcp"]
    }
  }
}

This gives your agent five security tools:

Claude Code users: ask your agent to run tooltrust_scan_config to audit every MCP server in your project in one shot.

🤝 Contribute

Request a scan — open an issue with the tool's public URL and version.

Dispute a finding — open an issue referencing the finding ID (e.g. AS-002).

Integrate ToolTrust Scanner — see docs/dev.md for the data pipeline and schema spec.

📛 Add to your README

If your MCP server was audited and earned a grade, add our badge to your repo:

Grade A (recommended) — copy this into your README:

[![ToolTrust Grade A](https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-directory/main/docs/badges/grade-a.svg)](https://github.com/AgentSafe-AI/tooltrust-directory)

Other grades — replace grade-a with grade-s, grade-b, grade-c, grade-d, or grade-f:

Grade	Badge

⚙️ Automation

The registry table above is kept up to date by a daily GitHub Actions workflow:

.github/workflows/daily-audit.yml   ← cron 00:00 UTC + manual dispatch

Each run:

1. Discovers popular MCP servers via GitHub Search (50+ stars) plus Smithery-native servers (10+ uses)
2. Scans new/updated tools with ToolTrust Scanner + OSV supply-chain analysis
3. Publishes updated reports to data/reports/ and regenerates this README
