CLI Tool - PromptGuard

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.

Installation

macOS (Homebrew)

brew tap promptguard/tap
brew install promptguard

Linux / macOS (Binary)

curl -fsSL https://get.promptguard.co/cli | bash

Cargo (Rust)

cargo install promptguard

Verify Installation

promptguard --version
# promptguard-cli 1.1.1

Quick Start

Scan Your Project

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

promptguard init

This interactively:

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

Commands

`promptguard scan`

Scan for unprotected LLM SDK calls.

promptguard scan [path] [options]

`--exclude <glob>`	Skip matching files
`--ci`	CI mode: exit code 1 if issues found

Examples:

# 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

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

`promptguard init`

Initialize PromptGuard SDK in your project.

promptguard init [options]

Option	Description
`--api-key <key>`	PromptGuard API key (or use env var)
`--mode <mode>`	`enforce` (default) or `monitor`
`--dry-run`	Show what would change without modifying files

`promptguard check`

Check if protection is properly configured.

promptguard check

Output:

[ok] PromptGuard SDK installed (v1.2.0)
[ok] promptguard.init() found in src/main.py
[ok] PROMPTGUARD_API_KEY environment variable set
[ok] All 12 LLM calls are protected

Your project is protected.

`promptguard fix`

Auto-fix unprotected calls by adding SDK initialization.

`promptguard policy`

Manage guardrail configurations as YAML files (policy-as-code).

promptguard policy <action> [options]

Action	Description
`apply <file>`	Apply a YAML policy file to the project
`diff <file>`	Show differences between YAML and live config
`export`	Export current live config as YAML to stdout

Option	Description
`--project-id <id>`	Project ID (required)
`--dry-run`	Preview changes without applying (apply only)
`--api-key <key>`	API key (or use configured key)

Examples:

# Export current config
promptguard policy export --project-id proj_abc > policy.yaml

# See what would change
promptguard policy diff policy.yaml --project-id proj_abc

# Apply with preview
promptguard policy apply policy.yaml --project-id proj_abc --dry-run

# Apply for real
promptguard policy apply policy.yaml --project-id proj_abc

Supported Providers

Provider	Python	JavaScript/TypeScript
OpenAI	Yes	Yes
Anthropic	Yes	Yes
Google AI	Yes	Yes
Cohere	Yes	Yes
AWS Bedrock	Yes	Yes
Azure OpenAI	Yes	Yes

This table is generated from sdk-patterns.json, the single source of truth the scanner reads. Mistral and Groq were previously listed here but have never been in it, and neither SDK patches them — the rows advertised detection that did not exist. Azure OpenAI is detected through the OpenAI patterns (AzureOpenAI is one of the recognised class names).

Configuration

`.promptguardrc`

Create a config file in your project root:

# .promptguardrc
scan:
  include:
    - "src/**/*.py"
    - "src/**/*.ts"
  exclude:
    - "**/*test*"
    - "**/node_modules/**"
    - "**/__pycache__/**"

init:
  mode: enforce
  entry_point: src/main.py

providers:
  - openai
  - anthropic

Environment Variables

Variable	Description
`PROMPTGUARD_API_KEY`	API key for `init` command
`PROMPTGUARD_LOG_LEVEL`	`debug`, `info`, `warn`, `error`
`NO_COLOR`	Disable colored output

    "unprotected": 3
  },
  "findings": [
    {
      "file": "src/api/chat.py",

}

SARIF

GitHub Code Scanning compatible format:

promptguard scan --format sarif > results.sarif

Upload to GitHub:

gh api repos/{owner}/{repo}/code-scanning/sarifs \
  -X POST \
  -F sarif=@results.sarif

Troubleshooting

Command not found after installation

Solution: Add to PATH

# macOS/Linux
export PATH="$HOME/.cargo/bin:$PATH"

# Or reinstall with Homebrew
brew reinstall promptguard

No LLM calls detected

Check:

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

False positives in comments/strings

The CLI uses AST parsing, not regex. If you see false positives:

Report at github.com/promptguard/cli/issues
Use --exclude to skip problematic files

MCP Server

The CLI includes a native MCP server for AI-powered editors:

promptguard mcp -t stdio

This lets Cursor, Claude Code, Windsurf, and other MCP-compatible editors call PromptGuard tools directly. See the MCP docs or Cursor plugin for setup instructions.
