Prowler MCP Server brings the entire Prowler ecosystem to AI assistants through the Model Context Protocol (MCP). It enables seamless integration with AI tools like Claude Desktop, Cursor, and other MCP clients, allowing interaction with Prowler's security capabilities through natural language.

Preview Feature: This MCP server is currently under active development. Features and functionality may change. We welcome your feedback—please report any issues on GitHub or join our Slack community.

Deployment Options

Prowler MCP Server can be used in three ways:

1. Prowler Cloud MCP Server (Recommended)

Use Prowler's managed MCP server at https://mcp.prowler.com/mcp

No installation required
Managed and maintained by Prowler team
Always up-to-date

{
  "mcpServers": {
    "prowler": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.prowler.com/mcp",
        "--header",
        "Authorization: Bearer pk_YOUR_API_KEY_HERE"
      ]
    }
  }
}

2. Local STDIO Mode

Run the server locally on your machine

Runs as a subprocess of your MCP client
Requires Python 3.12+ or Docker

3. Self-Hosted HTTP Mode

Deploy your own remote MCP server

Full control over deployment
Requires Python 3.12+ or Docker

See the Installation Guide for complete instructions.

Quick Installation

Docker (Recommended)

docker pull prowlercloud/prowler-mcp

# STDIO mode
docker run --rm -i prowlercloud/prowler-mcp

# HTTP mode
docker run --rm -p 8000:8000 prowlercloud/prowler-mcp --transport http --host 0.0.0.0 --port 8000

From Source

git clone https://github.com/prowler-cloud/prowler.git
cd prowler/mcp_server
uv run prowler-mcp --help

Available Tools

For complete tool descriptions and parameters, see the Tools Reference.

Tool Naming Convention

All tools follow a consistent naming pattern with prefixes:

prowler_app_* - Prowler Cloud and App (Self-Managed) management tools
prowler_hub_* - Prowler Hub catalog and compliance tools
prowler_docs_* - Prowler documentation search and retrieval

Architecture

prowler_mcp_server/
├── server.py                 # Main orchestrator (imports sub-servers with prefixes)
├── main.py                   # CLI entry point
├── prowler_hub/              # tools - no authentication required
├── prowler_app/              # tools - authentication required
│   ├── tools/                # Tool implementations
│   ├── models/               # Pydantic models for LLM-optimized responses
│   └── utils/                # API client, authentication, tool loader
└── prowler_documentation/    # tools - no authentication required

Key Features:

Modular Design: Three independent sub-servers with prefixed namespacing
Auto-Discovery: Prowler App tools are automatically discovered and registered
LLM Optimization: Response models minimize token usage by excluding empty values
Dual Transport: Supports both STDIO (local) and HTTP (remote) modes

Use Cases

The Prowler MCP Server enables powerful workflows through AI assistants:

Security Operations

"Show me all critical findings from my AWS production accounts"
"Register my new AWS account in Prowler and run a scheduled scan every day"
"List all muted findings and detect what findgings are muted by a not enough good reason in relation to their severity"

Security Research

"Explain what the S3 bucket public access Prowler check does"
"Find all Prowler checks related to encryption at rest"
"What is the latest version of the CIS that Prowler is covering per provider?"

Documentation & Learning

"How do I configure Prowler to scan my GCP organization?"
"What authentication methods does Prowler support for Azure?"
"How can I contribute with a new security check to Prowler?"

Requirements

For Prowler Cloud MCP Server:

Prowler Cloud account and API key (only for Prowler Cloud/App features)

For self-hosted STDIO/HTTP Mode:

Python 3.12+ or Docker
Network access to:
- https://hub.prowler.com (for Prowler Hub)
- https://docs.prowler.com (for Prowler Documentation)
- Prowler Cloud API or self-hosted Prowler App API (for Prowler Cloud/App features)

No Authentication Required: Prowler Hub and Prowler Documentation features work without authentication. A Prowler API key is only required to access Prowler Cloud or Prowler App (Self-Managed) features.

Configuring MCP Hosts

To configure your MCP host (Claude Code, Cursor, etc.) see the Configuration Guide for detailed setup instructions.
