Prowler MCP Server

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.

Key Capabilities

Prowler Cloud, Prowler Private Cloud & Prowler Local Server

Full access to your Prowler data (Prowler Cloud, Prowler Private Cloud, or Prowler Local Server) for:

• Findings Analysis: Query, filter, and analyze security findings across all your cloud environments
• Finding Groups Analysis: Triage findings grouped by check ID and drill down into affected resources
• Provider Management: Create, configure, and manage your configured Prowler providers (AWS, Azure, GCP, etc.)
• Scan Orchestration: Trigger on-demand scans, track their progress, and schedule a daily scan
• Resource Inventory: Search and view detailed information about your audited resources
• Muting Management: Create and manage muting rules to suppress non-critical findings
• Compliance Reporting: View compliance status across frameworks and drill into requirement-level details
• Attack Paths Analysis: Analyze privilege escalation chains through graph-based analysis of cloud resource relationships
• Integrations Management: Set up and troubleshoot where Prowler sends its results (Amazon S3, AWS Security Hub, Jira), and turn findings into Jira work items
• User & Role Management: List the users in your tenant, identify the authenticated user, browse RBAC roles, and set the role a user holds

Prowler Cloud Management

Prowler Cloud-only workflow and configuration features (prowler_cloud_* tools). These are available only on the hosted Prowler MCP, since they manage features that exist only in Prowler Cloud:

• Scan Configurations: Read, create, update, and delete reusable scan configurations and attach them to providers (providers without one use the default)
• Findings Triage: Read and set a finding's triage status and leave notes documenting the decision, without suppressing the finding
• Scan Scheduling: Read and configure recurring scan schedules (daily, interval, weekly, monthly), one provider at a time or in bulk
• Alerts: Read and manage alert rules and recipients, dry-run rule conditions before saving, and browse the fired-alert history

Prowler Hub

Access to Prowler's comprehensive security knowledge base:

• Security Checks Catalog: Browse and search over 2,000 security checks across multiple Prowler providers
• Check Implementation: View the Python code that powers each security check
• Automated Fixers: Access remediation scripts for common security issues
• Compliance Frameworks: Explore mappings to over 70 compliance standards and frameworks
• Provider Services: View available services and checks for all supported Prowler providers

Prowler Documentation

Search and retrieve official Prowler documentation:

• Intelligent Search: Full-text search across all Prowler documentation
• Contextual Results: Get relevant documentation pages with highlighted snippets
• Document Retrieval: Access complete markdown content of any documentation file

Deployment Options

Prowler MCP Server can be used in three ways:

1. Hosted Prowler MCP (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

Install a reviewed version of mcp-remote in a dedicated local workspace first. Avoid running npx mcp-remote directly because it can download and execute a new package version on each run.

mkdir -p ~/.local/share/prowler-mcp-bridge
cd ~/.local/share/prowler-mcp-bridge
npm init -y
npm install --save-exact mcp-remote@0.1.38

{
  "mcpServers": {
    "prowler": {
      "command": "/absolute/path/to/.local/share/prowler-mcp-bridge/node_modules/.bin/mcp-remote",
      "args": [
        "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_* - Prowler Cloud, Prowler Private Cloud & Prowler Local Server management tools
• prowler_cloud_* - Prowler Cloud-only management tools (hosted Prowler MCP only)
• prowler_hub_* - Prowler Hub catalog and compliance tools
• prowler_docs_* - Prowler documentation search and retrieval

Architecture

prowler_mcp_server/
├── server.py                 # Main orchestrator (mounts sub-servers with namespaces)
├── 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 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 flag the ones whose mute reason is too weak for their severity"
• "Send my failed CIS findings for this provider to Jira as work items"

Prowler Cloud Management

• "Preview an alert rule for critical AWS findings and create it for my confirmed recipients"
• "Show the triage notes for this finding and mark it as under review"
• "Apply a weekly Monday 06:00 scan schedule to every AWS provider"
• "Create a scan configuration that runs only CIS checks and attach it to my production providers"

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 the hosted Prowler MCP:

• Prowler Cloud account and API key (only for Prowler 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 Prowler Local Server API (for Prowler features)

No Authentication Required: Prowler Hub and Prowler Documentation features work without authentication. A Prowler API key is only required for the prowler_* and prowler_cloud_* tools (Prowler Cloud, Prowler Private Cloud, or Prowler Local Server).

Configuring MCP Hosts

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