API Credentials & Required Scopes

Setting Up CrowdStrike API Credentials

Before using the Falcon MCP Server, you need to create API credentials in your CrowdStrike console:

1. Log into your CrowdStrike console
2. Navigate to Support > API Clients and Keys
3. Click "Add new API client"
4. Configure your API client:
   • Client Name: Choose a descriptive name (e.g., "Falcon MCP Server")
   • Description: Optional description for your records
   • API Scopes: Select the scopes based on which modules you plan to use (see below)

Required API Scopes by Module

Available Modules, Tools & Resources

[!IMPORTANT] ⚠️ Important Note on FQL Guide Resources: Several modules include FQL (Falcon Query Language) guide resources that provide comprehensive query documentation and examples. While these resources are designed to assist AI assistants and users with query construction, FQL has nuanced syntax requirements and field-specific behaviors that may not be immediately apparent. AI-generated FQL filters should be tested and validated before use in production environments. We recommend starting with simple queries and gradually building complexity while verifying results in a test environment first.

About Tools & Resources: This server provides both tools (actions you can perform) and resources (documentation and context). Tools execute operations like searching for detections or analyzing threats, while resources provide comprehensive documentation like FQL query guides that AI assistants can reference for context without requiring tool calls.

Environment Configuration

Copy the example environment file and configure your credentials:

cp .env.example .env

Then edit .env with your CrowdStrike API credentials:

Required Configuration:

• FALCON_CLIENT_ID: Your CrowdStrike API client ID
• FALCON_CLIENT_SECRET: Your CrowdStrike API client secret
• FALCON_BASE_URL: Your CrowdStrike API region URL (see options in .env.example)

Optional Configuration:

• FALCON_MCP_HOST: Host for HTTP transports (default: 127.0.0.1)
• FALCON_MCP_PORT: Port for HTTP transports (default: 8000)

Alternatively, you can set these as environment variables instead of using a .env file.

Important: Ensure your API client has the necessary scopes for the modules you plan to use. You can always update scopes later in the CrowdStrike console.

Installation

Install using uv

uv tool install falcon-mcp

Install using pip

pip install falcon-mcp

[!TIP] If falcon-mcp isn't found, update your shell PATH.

For installation via code editors/assistants, see the Editor/Assitant section below

Usage

Command Line

Run the server with default settings (stdio transport):

falcon-mcp

Run with SSE transport:

falcon-mcp --transport sse

Run with streamable-http transport:

falcon-mcp --transport streamable-http

Run with streamable-http transport on custom port:

falcon-mcp --transport streamable-http --host 0.0.0.0 --port 8080

Module Configuration

The Falcon MCP Server supports multiple ways to specify which modules to enable:

1. Command Line Arguments (highest priority)

Specify modules using comma-separated lists:

# Enable specific modules
falcon-mcp --modules detections,incidents,intel,spotlight,idp

# Enable only one module
falcon-mcp --modules detections

2. Environment Variable (fallback)

Set the FALCON_MCP_MODULES environment variable:

# Export environment variable
export FALCON_MCP_MODULES=detections,incidents,intel,spotlight,idp
falcon-mcp

# Or set inline
FALCON_MCP_MODULES=detections,incidents,intel,spotlight,idp falcon-mcp

3. Default Behavior (all modules)

If no modules are specified via command line or environment variable, all available modules are enabled by default.

Module Priority Order:

1. Command line --modules argument (overrides all)
2. FALCON_MCP_MODULES environment variable (fallback)
3. All modules (default when none specified)
