## 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)

> **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.

### Required API Scopes by Module

The Falcon MCP Server supports different modules, each requiring specific API scopes:

| Module | Required API Scopes | Purpose |
|-|-|-|
| **Cloud Security** | `Falcon Container Image:read` | Find and analyze kubernetes containers inventory and container imges vulnerabilities |
| **Core** | _No additional scopes_ | Basic connectivity and system information |

## 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

You can configure your CrowdStrike API credentials in several ways:

#### Use a `.env` File

If you prefer using a `.env` file, you have several options:

##### Option 1: Copy from cloned repository (if you've cloned it)

```bash
cp .env.example .env
```

##### Option 2: Download the example file from GitHub

```bash
curl -o .env https://raw.githubusercontent.com/CrowdStrike/falcon-mcp/main/.env.example
```

##### Option 3: Create manually with the following content

```bash
# Required Configuration
FALCON_CLIENT_ID=your-client-id
FALCON_CLIENT_SECRET=your-client-secret
FALCON_BASE_URL=https://api.crowdstrike.com

# Optional Configuration (uncomment and modify as needed)

#FALCON_MCP_TRANSPORT=stdio
#FALCON_MCP_DEBUG=false
#FALCON_MCP_HOST=127.0.0.1
#FALCON_MCP_PORT=8000
```

#### Environment Variables

Alternatively, you can use environment variables directly.

Set the following environment variables in your shell:

```bash
# Required Configuration
export FALCON_CLIENT_ID="your-client-id"
export FALCON_CLIENT_SECRET="your-client-secret"
export FALCON_BASE_URL="https://api.crowdstrike.com"

### Installation

#### Install using uv

```bash
uv tool install falcon-mcp
```

#### Install using pip

```bash
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](#editorassistant-integration) section below

## Usage

### Command Line

Run the server with default settings (stdio transport):

```bash
falcon-mcp
```

Run with SSE transport:

```bash
falcon-mcp --transport sse
```

Run with streamable-http transport:

```bash
falcon-mcp --transport streamable-http
```

Run with streamable-http transport on custom port:

```bash
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:

```bash
# 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:

```bash
# 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)

### Additional Command Line Options

For all available options:

```bash
falcon-mcp --help
```

### As a Library

```python
from falcon_mcp.server import FalconMCPServer

# Create and run the server
server = FalconMCPServer(
    base_url="https://api.us-2.crowdstrike.com",  # Optional, defaults to env var
    debug=True,  # Optional, enable debug logging
    enabled_modules=["detections", "incidents", "spotlight", "idp"]  # Optional, defaults to all modules
)

# Run with stdio transport (default)
server.run()

# Or run with SSE transport
server.run("sse")

# Or run with streamable-http transport
server.run("streamable-http")

# Or run with streamable-http transport on custom host/port
server.run("streamable-http", host="0.0.0.0", port=8080)
```

### Running Examples

```bash
# Run with stdio transport
python examples/basic_usage.py

# Run with SSE transport
python examples/sse_usage.py

# Run with streamable-http transport
python examples/streamable_http_usage.py
```

## Container Usage

The Falcon MCP Server is available as a pre-built container image for easy deployment:

### Using Pre-built Image (Recommended)

```bash
# Pull the latest pre-built image
docker pull quay.io/crowdstrike/falcon-mcp:latest

# Run with .env file (recommended)
docker run -i --rm --env-file /path/to/.env quay.io/crowdstrike/falcon-mcp:latest

# Run with .env file and SSE transport
docker run --rm -p 8000:8000 --env-file /path/to/.env \
  quay.io/crowdstrike/falcon-mcp:latest --transport sse --host 0.0.0.0

# Run with .env file and streamable-http transport
docker run --rm -p 8000:8000 --env-file /path/to/.env \
  quay.io/crowdstrike/falcon-mcp:latest --transport streamable-http --host 0.0.0.0

# Run with .env file and custom port
docker run --rm -p 8080:8080 --env-file /path/to/.env \
  quay.io/crowdstrike/falcon-mcp:latest --transport streamable-http --host 0.0.0.0 --port 8080

# Run with .env file and specific modules (stdio transport - requires -i flag)
docker run -i --rm --env-file /path/to/.env \
  quay.io/crowdstrike/falcon-mcp:latest --modules detections,incidents,spotlight,idp

# Use a specific version instead of latest (stdio transport - requires -i flag)
docker run -i --rm --env-file /path/to/.env \
  quay.io/crowdstrike/falcon-mcp:1.2.3

# Alternative: Individual environment variables (stdio transport - requires -i flag)
docker run -i --rm -e FALCON_CLIENT_ID=your_client_id -e FALCON_CLIENT_SECRET=your_secret \
  quay.io/crowdstrike/falcon-mcp:latest
```

### Building Locally (Development)

For development or customization purposes, you can build the image locally:

```bash
# Build the Docker image
docker build -t falcon-mcp .

# Run the locally built image
docker run --rm -e FALCON_CLIENT_ID=your_client_id -e FALCON_CLIENT_SECRET=your_secret falcon-mcp
```

> [!NOTE]
> When using HTTP transports in Docker, always set `--host 0.0.0.0` to allow external connections to the container.
