pretorin 0.2.1

CLI and MCP server for Pretorin Compliance API

AI Compliance tools for developers.

---

We believe that compliance should be easy for developers. We now have AI machines the can write the detailed security documents that used to rob developers of their time and focus. We are building the tool kit to make this a reality. To that end, this is a CLI and MCP server for the Pretorin Compliance Platform API. It makes it easy to bring high quality compliance context into your favorite AI tool. Access enriched compliance framework data, control families, and control details from NIST 800-53, NIST 800-171, FedRAMP, CMMC, and many more to come

Installation

Stable (PyPI)

pip install pretorin

We recommend using uv or pipx for isolated installation:

uv tool install pretorin

pipx install pretorin

Latest (GitHub)

Install the latest development version directly from GitHub:

pip install git+https://github.com/pretorin-ai/pretorin-cli.git

Or with uv:

uv tool install git+https://github.com/pretorin-ai/pretorin-cli.git

Updating

Check for updates and upgrade:

pretorin update

Quick Start

Get your API key from https://platform.pretorin.com/, then authenticate:

pretorin login

Verify your authentication:

pretorin whoami

MCP Integration

The Pretorin CLI includes an MCP (Model Context Protocol) server that enables AI assistants to access compliance framework data directly during conversations.

Why MCP?

• Real-time data — Query the latest compliance frameworks and controls
• Reduce hallucination — Work with authoritative compliance data instead of training knowledge
• Streamline workflows — No copy-pasting between tools

Setup

Install and authenticate first:

uv tool install pretorin
pretorin login

Then add Pretorin to your AI tool of choice:

Claude Desktop

Add to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "pretorin": {
      "command": "pretorin",
      "args": ["mcp-serve"]
    }
  }
}

Restart Claude Desktop after saving.

Claude Code

Quick setup — run a single command:

claude mcp add --transport stdio pretorin -- pretorin mcp-serve

This registers the server for your current project. To make it available across all your projects, add --scope user.

Team setup — add a .mcp.json file to your project root so every team member gets the server automatically:

{
  "mcpServers": {
    "pretorin": {
      "type": "stdio",
      "command": "pretorin",
      "args": ["mcp-serve"]
    }
  }
}

Claude Code will detect the file automatically.

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "pretorin": {
      "command": "pretorin",
      "args": ["mcp-serve"]
    }
  }
}

Restart Cursor after saving.

OpenAI Codex CLI

Add to ~/.codex/config.toml:

[mcp_servers.pretorin]
command = "pretorin"
args = ["mcp-serve"]

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "pretorin": {
      "command": "pretorin",
      "args": ["mcp-serve"]
    }
  }
}

Restart Windsurf after saving.
