Prowler MCP Server

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

Access the entire Prowler ecosystem through the Model Context Protocol (MCP). This server provides two main capabilities:

• Prowler Cloud and Prowler App (Self-Managed): Full access to Prowler Cloud platform and Prowler Self-Managed for managing providers, running scans, and analyzing security findings
• Prowler Hub: Access to Prowler's security checks, fixers, and compliance frameworks catalog

Requirements

• Python 3.12+
• Network access to https://hub.prowler.com (for Prowler Hub)
• Network access to Prowler Cloud and Prowler App (Self-Managed) API (it can be Prowler Cloud API or self-hosted Prowler App API)
• Prowler Cloud account credentials (for Prowler Cloud and Prowler App (Self-Managed) features)

Installation

From Sources

It is needed to have uv installed.

git clone https://github.com/prowler-cloud/prowler.git

Using Docker

Alternatively, you can build and run the MCP server using Docker:

# Clone the repository
git clone https://github.com/prowler-cloud/prowler.git
cd prowler/mcp_server

# Build the Docker image
docker build -t prowler-mcp .

# Run the container with environment variables
docker run --rm --env-file ./.env -it prowler-mcp

Running

The Prowler MCP server supports two transport modes:

• STDIO mode (default): For direct integration with MCP clients like Claude Desktop
• HTTP mode: For remote access over HTTP with Bearer token authentication

Transport Modes

STDIO Mode (Default)

STDIO mode is the standard MCP transport for direct client integration:

cd prowler/mcp_server
uv run prowler-mcp
# or
uv run prowler-mcp --transport stdio

HTTP Mode (Remote Server)

HTTP mode allows the server to run as a remote service accessible over HTTP:

cd prowler/mcp_server
# Run on default host and port (127.0.0.1:8000)
uv run prowler-mcp --transport http

# Run on custom host and port
uv run prowler-mcp --transport http --host 0.0.0.0 --port 8080

For self-deployed MCP remote server, you can use also configure the server to use a custom API base URL with the environment variable PROWLER_API_BASE_URL; and the transport mode with the environment variable PROWLER_MCP_MODE.

export PROWLER_API_BASE_URL="https://api.prowler.com"
export PROWLER_MCP_MODE="http"

Using uv directly

After installation, start the MCP server via the console script:

cd prowler/mcp_server
uv run prowler-mcp

Alternatively, you can run from wherever you want using uvx command:

uvx /path/to/prowler/mcp_server/

Using Docker

STDIO Mode (Default)

Run the pre-built Docker container in STDIO mode:

cd prowler/mcp_server
docker run --rm --env-file ./.env -it prowler-mcp

HTTP Mode (Remote Server)

Run as a remote HTTP server:

cd prowler/mcp_server
# Run on port 8000 (accessible from host)
docker run --rm --env-file ./.env -p 8000:8000 -it prowler-mcp --transport http --host 0.0.0.0 --port 8000

# Run on custom port
docker run --rm --env-file ./.env -p 8080:8080 -it prowler-mcp --transport http --host 0.0.0.0 --port 8080

Command Line Arguments

The Prowler MCP server supports the following command line arguments:

prowler-mcp [--transport {stdio,http}] [--host HOST] [--port PORT]

Arguments:

• --transport {stdio,http}: Transport method (default: stdio)
  • stdio: Standard input/output transport for direct MCP client integration
  • http: HTTP transport for remote server access
• --host HOST: Host to bind to for HTTP transport (default: 127.0.0.1)
• --port PORT: Port to bind to for HTTP transport (default: 8000)

Examples:

# Default STDIO mode
prowler-mcp

# Explicit STDIO mode
prowler-mcp --transport stdio

# HTTP mode with default host and port (127.0.0.1:8000)
prowler-mcp --transport http

# HTTP mode accessible from any network interface
prowler-mcp --transport http --host 0.0.0.0

# HTTP mode with custom port
prowler-mcp --transport http --host 0.0.0.0 --port 8080

Configuration

Prowler Cloud and Prowler App (Self-Managed) Authentication

Important

Authentication is not needed for using Prowler Hub features.

The Prowler MCP server supports different authentication in Prowler Cloud and Prowler App (Self-Managed) methods depending on the transport mode:

STDIO Mode Authentication

For STDIO mode, authentication is handled via environment variables:

# Required for Prowler Cloud and Prowler App (Self-Managed) authentication
export PROWLER_APP_EMAIL="your-email@example.com"
export PROWLER_APP_PASSWORD="your-password"

# Optional - in case not provided the first membership that was added to the user will be used. This can be found as `Organization ID` in your User Profile in Prowler App
export PROWLER_APP_TENANT_ID="your-tenant-id"

# Optional - for custom API endpoint, in case not provided Prowler Cloud API will be used
export PROWLER_API_BASE_URL="https://api.prowler.com"

HTTP Mode Authentication

For HTTP mode (remote server), authentication is handled via Bearer tokens. You need to obtain a JWT token from Prowler Cloud/App and include the generated token in the MCP client configuration. To get a valid token, you can use the following command (replace the email and password with your own credentials):

curl -X POST https://api.prowler.com/api/v1/tokens \
  -H "Content-Type: application/vnd.api+json" \
  -H "Accept: application/vnd.api+json" \
  -d '{
    "data": {
      "type": "tokens",
      "attributes": {
        "email": "your-email@example.com",
        "password": "your-password"
      }
    }
  }'

The response will be a JWT token that you can use to authenticate your MCP client.

MCP Client Configuration

Configure your MCP client, like Claude Desktop, Cursor, etc, to connect to the server. The configuration depends on whether you're running in STDIO mode (local) or HTTP mode (remote).

STDIO Mode Configuration

For local execution, configure your MCP client to launch the server directly. Below are examples for both direct execution and Docker deployment; consult your client's documentation for exact locations.

Using uvx (Direct Execution)

{
  "mcpServers": {
    "prowler": {
      "command": "uvx",
      "args": ["/path/to/prowler/mcp_server/"],
      "env": {
        "PROWLER_APP_EMAIL": "your-email@example.com",
        "PROWLER_APP_PASSWORD": "your-password",
        "PROWLER_APP_TENANT_ID": "your-tenant-id",  // Optional, this can be found as `Organization ID` in your User Profile in Prowler App,
        "PROWLER_API_BASE_URL": "https://api.prowler.com"  // Optional, in case not provided Prowler Cloud API will be used
      }
    }
  }
}

Using Docker

{
  "mcpServers": {
    "prowler": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "--env", "PROWLER_APP_EMAIL=your-email@example.com",
        "--env", "PROWLER_APP_PASSWORD=your-password",
        "--env", "PROWLER_APP_TENANT_ID=your-tenant-id",  // Optional, this can be found as `Organization ID` in your User Profile in Prowler App
        "--env", "PROWLER_API_BASE_URL=https://api.prowler.com",  // Optional, in case not provided Prowler Cloud API will be used
        "prowler-mcp"
      ]
    }
  }
}

HTTP Mode Configuration (Remote Server)

For HTTP mode, you can configure your MCP client to connect to a remote Prowler MCP server.

Important Limitations:

• HTTP mode support varies by client - some clients may not support HTTP transport yet.
• Some MCP clients like Claude Desktop only support OAuth authentication for HTTP connections, which is not currently supported by our MCP server.

Example configuration for clients that support HTTP transport:

{
  "mcpServers": {
    "prowler": {
      "url": "http://mcp.prowler.com/mcp",  // Replace with your own MCP server URL, by default when server is run in local it is http://localhost:8000/mcp
      "headers": {
        "Authorization": "Bearer <your-jwt-token-here>"
      }
    }
  }
}

Claude Desktop (macOS/Windows)

Add the example server to Claude Desktop's config file, then restart the app.

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %AppData%\Claude\claude_desktop_config.json (e.g. C:\\Users\\<you>\\AppData\\Roaming\\Claude\\claude_desktop_config.json)

Cursor (macOS/Linux)

If you want to have it globally available, add the example server to Cursor's config file, then restart the app.

• macOS/Linux: ~/.cursor/mcp.json

If you want to have it only for the current project, add the example server to the project's root in a new .cursor/mcp.json file.
