CodeGuard AI 🛡️

Security agents running inside E2B sandboxes, connecting to real-world tools via Docker MCP servers

CodeGuard AI: The CodeRabbit Killer for Security

While tools like CodeRabbit provide general code review suggestions, CodeGuard AI specializes in security by actually proving vulnerabilities are exploitable—no false positives, just confirmed threats.

What It Is

CodeGuard AI is an autonomous security agent that scans GitHub pull requests for vulnerabilities and proves they're exploitable by safely executing exploits inside isolated E2B sandboxes.

Why It Exists

Traditional security scanners flood developers with hundreds of potential vulnerabilities but can't tell you which ones are actually exploitable. This wastes time investigating false positives or risks missing real threats.

How It Solves It

CodeGuard AI runs security agents entirely inside E2B microVMs, where exploits can be safely tested without risk. The agent uses MCP clients to seamlessly connect to GitHub, automatically fetching PR files, analyzing code, executing exploit tests, and posting detailed security reports with fix suggestions directly to pull requests.

Key Innovation: The agent runs inside an E2B sandbox to find and prove real exploits.

Quick Start

1. Install dependencies: pip install -r requirements.txt
2. Configure API keys: Copy config.json.example to config.json and add your API keys
3. Start GitHub MCP Server: docker-compose up -d
4. Launch Dashboard: streamlit run dashboard.py
