Trust & Security for AI Agents & MCP Servers

OpenTrustBench

Scan your AI agent or MCP server for vulnerabilities.
Get a verifiable Trust Card with a public grade badge.

What is OpenTrustBench?

OpenTrustBench is a trust and security verification platform for autonomous AI agents and MCP (Model Context Protocol) servers. It scans your codebase for vulnerabilities, maps findings to OWASP Agentic AI Top 10 and OWASP LLM Top 10 2025, generates a verifiable Trust Card with a letter grade, and provides a shareable badge for your README.

Zero data retention. Everything runs locally on your machine. No telemetry. No account required.

Quick Start

# Scan a local folder, MCP server, or Agent Skill
npx @opentrustbench/cli scan ./my-mcp-server

# Scan a GitHub repository
npx @opentrustbench/cli scan https://github.com/owner/repo

# Scan an npm package
npx @opentrustbench/cli scan some-npm-package --npm

# Fail CI when findings meet a severity threshold
npx @opentrustbench/cli scan ./my-mcp-server --fail-on high

# Run the OWASP Agentic Top 10 Adversarial Attack Suite
npx @opentrustbench/cli attack ./my-mcp-server

# Evaluate workflow reliability
npx @opentrustbench/cli eval ./tests/workflow.yaml

What You Get

Grade Badge

Embed your trust score in your README:

[![OpenTrustBench](https://www.opentrustbench.com/r/self-packages-cli.svg)](https://www.opentrustbench.com/r/self-packages-cli.html)

This tells buyers, auditors, and AI hosts that your agent has been verified.

How It Works

1. Scan — Point opentrustbench at a local directory, GitHub repo, or npm package
2. Grade — Receive a Trust Card with a letter grade (A–F) and security score (0–100)
3. Share — Embed your badge and link to the detailed report

Features

• 8 detection rules across shell injection, secret leaks, prompt injection, tool exploitation, and more
• OWASP mapping — Every finding tagged to OWASP Agentic Top 10 (ASI01–ASI10) and LLM Top 10 2025 (LLM01–LLM10)
• Permission manifest — Automatic extraction and scoping of agent permissions
• Dependency audit — npm audit integration for lockfile-based vulnerability detection
• SARIF output — Native GitHub Code Scanning integration
• CI integration — --fail-on severity gate for pipeline enforcement
• GitHub Action — Drop-in composite action for workflows
• GitHub URL detection — Scan any public repo by URL
• Compliance helpers — Permission manifests and audit trails to attach to an EU AI Act review (evidence input, not a certification)

What the scanner is (and isn't)

• 8-rule static suite, OWASP-mapped (Agentic ASI01–ASI10, LLM LLM01–LLM10). Regex-based today — no AST yet.
• attack is static-heuristic: it re-analyzes scan findings + permissions. No payloads execute.
• eval is simulation mode: suites are parsed and validated; nothing runs, costs/durations stay 0.
• Not a certification. The Trust Card is a CI-grade credential, not a pentest or legal verdict.
