🛡️ The Puli Guardian MCP

Puli Reviewer

is a proactive security and stability guardrail for your AI coding agents (Claude Code, Cursor, Antigravity, etc.). It prevents production breakages by confronting proposed code changes with a massive, real-time database of global incidents, edge cases, and security breaches.

Stop production errors before they happen.

Puli acts as a real-time bridge between your local development and global production insights. It doesn't just check syntax—it checks reality.

• Real-time Intelligence: Connects to a live DB of global incidents.
• Agent Native: Built specifically for the MCP ecosystem.
• IP Protection: Choose between BYOK or zero-retention cloud.

How do I install it?

🚀 How it Works

Whenver your coding agent attempts to modify your codebase,
Puli:

1. Analyzes the Context:
   Queries the agent to understand the intent of
   the change.

2. Cross-References Failures:
   Matches the code against a live-updated DB
   of real-world production errors and business-flow
   disruptions.

3. Stress Tests:
   Forces the agent to account for specific edge
   cases before the code is ever committed.

⚙️ Installation & Setup

1. Configure the MCP Server

Add the following to your coding agent's configuration (e.g., claude_desktop_config.json or your IDE's MCP settings):

{
  "mcpServers": {
    "puli-viewer": {
      "command": "uvx",
      "args": ["--from", "puli-mcp-server@latest", "puli-reviewer"],
      "env": {
        "BYO_OPENAI_API_KEY": "Optional* - <your-key-if-using-byok>",
        "BYO_GOOGLE_API_KEY": "Optional* - <your-key-if-using-byok>",
        "BYO_ANTHROPIC_API_KEY": "Optional* - <your-key-if-using-byok>"
      }
    }
  }
}

• Provide at lease one API key

2. Add Agent Rules

To ensure your agent utilizes the guardrail for every change, add our rules file to your project:

• For Cursor: Create a file at .cursor/rules/puli-reviewer.md and paste the content from our rules template here.

🛡️ Privacy & Security

We prioritize your IP security, Operations run locally on your station and no code is shared with our cloud.

We support two distinct working modes:

Mode	Data Privacy
When OpenAI API key provided.	Local Only. We pass embedded vectors to be used for extracting DB patterns.
When no OpenAI API key provided.	Zero Retention. We embedd the semantical meanning of your code change in our cloud. Nothing is ever logged or stored.
