# CLI Tool

> Scan codebases for unprotected LLM calls from your terminal

<Info>
  The PromptGuard CLI scans your codebase locally to detect unprotected LLM SDK calls before you push to Git. It supports Python, JavaScript, and TypeScript projects.
</Info>

## Installation

### macOS (Homebrew)

```bash theme={"system"}
brew tap promptguard/tap
brew install promptguard
```

### Linux / macOS (Binary)

```bash theme={"system"}
curl -fsSL https://get.promptguard.co/cli | bash
```

### Cargo (Rust)

```bash theme={"system"}
cargo install promptguard
```

### Verify Installation

```bash theme={"system"}
promptguard --version
# promptguard-cli 1.1.1
```

## Quick Start

### Scan Your Project

```bash theme={"system"}
cd your-project
promptguard scan
```

Output:

```
Scanning your-project...

Found 3 unprotected LLM calls:

  [!] src/api/chat.py:45
      openai.chat.completions.create()
      Provider: OpenAI

  [!] src/agents/helper.ts:23
      anthropic.messages.create()
      Provider: Anthropic

  [!] lib/utils.py:89
      client.chat.completions.create()
      Provider: OpenAI

Summary:
  Total LLM calls: 12
  Protected: 9 (75%)
  Unprotected: 3 (25%)

Run `promptguard init` to add protection.
```

### Initialize Protection

```bash theme={"system"}
promptguard init
```

This interactively:

1. Detects which LLM providers you use
2. Installs the PromptGuard SDK
3. Adds `promptguard.init()` to your entry point
4. Shows you what changed

## Commands

### `promptguard scan`

Scan for unprotected LLM SDK calls.

```bash theme={"system"}
promptguard scan [path] [options]
```

| Option               | Description                                        |
| -------------------- | -------------------------------------------------- |
| `--format <fmt>`     | Output format: `pretty` (default), `json`, `sarif` |
| `--severity <level>` | Minimum severity: `low`, `medium`, `high`          |
| `--include <glob>`   | Only scan matching files                           |
| `--exclude <glob>`   | Skip matching files                                |
| `--ci`               | CI mode: exit code 1 if issues found               |

**Examples:**

```bash theme={"system"}
# Scan specific directory
promptguard scan ./src

# JSON output for CI pipelines
promptguard scan --format json

# SARIF for GitHub Code Scanning
promptguard scan --format sarif > results.sarif

# Only high severity
promptguard scan --severity high

# Exclude tests
promptguard scan --exclude "**/*test*"
```

### `promptguard init`

Initialize PromptGuard SDK in your project.

```bash theme={"system"}
promptguard init [options]
```

| Option              | Description                                    |

## Troubleshooting

<AccordionGroup>
  <Accordion title="Command not found after installation">
    **Solution**: Add to PATH

    ```bash theme={"system"}
    # macOS/Linux
    export PATH="$HOME/.cargo/bin:$PATH"

    # Or reinstall with Homebrew
    brew reinstall promptguard
    ```
  </Accordion>

  <Accordion title="No LLM calls detected">
    **Check**:

    * Are you in the right directory?
    * Are the files in the include patterns?
    * Try: `promptguard scan --include "**/*.py"`
  </Accordion>

  <Accordion title="False positives in comments/strings">
    The CLI uses AST parsing, not regex. If you see false positives:

    * Report at [github.com/promptguard/cli/issues](https://github.com/promptguard/cli/issues)
    * Use `--exclude` to skip problematic files
  </Accordion>
</AccordionGroup>

## MCP Server

The CLI includes a native [MCP server](/tools/mcp) for AI-powered editors:

```bash theme={"system"}
promptguard mcp -t stdio
```

This lets Cursor, Claude Code, Windsurf, and other MCP-compatible editors call PromptGuard tools directly. See the [MCP docs](/tools/mcp) or [Cursor plugin](/tools/cursor) for setup instructions.
