falcon-mcp-extended 0.9.0

Community extension of CrowdStrike's falcon-mcp MCP server with full Falcon API coverage (~1,296 tools)

falcon-mcp-extended

[!NOTE] This is a community extension of CrowdStrike's official falcon-mcp server (MIT licensed). It adds 106 auto-generated API wrapper modules (~904 additional tools) on top of the official curated tool set, for near-complete CrowdStrike Falcon API coverage. This project is not affiliated with, maintained by, or endorsed by CrowdStrike. If you only need the curated SOC workflows, use the official server; use this project when you need API surface the official server doesn't expose yet.

For SOC analysts and security engineers: Stop tab-switching between CrowdStrike, your ticketing system, and your notes. Ask Claude to triage the alert, pull the process tree, check if the hash ran on other hosts, and draft the IR note — all in one conversation.

falcon-mcp-extended is a Model Context Protocol (MCP) server that gives AI agents — including Claude — direct, structured access to the CrowdStrike Falcon platform for intelligent security operations.

What It Does

This server bridges AI assistants and the CrowdStrike Falcon platform, enabling SOC analysts to ask natural-language questions and get answers backed by live Falcon data. It exposes Falcon's detection, investigation, response, and intelligence capabilities as MCP tools, so an AI agent can search detections, pivot through behaviors, contain hosts, and query threat intelligence — all from a single conversation. Designed for both interactive SOC workflows and automated security pipelines, it supports MSSP Flight Control so multi-tenant environments can be queried without switching consoles.

What This Adds Over the Official Server

Layer	Module count	Approximate tool count	Enabled by default
Curated modules (from upstream, plus additions)	50	~392	Yes
Auto-generated API wrappers (gen_*) — this project's addition	106	~904 additional	No (opt-in)

The default mode exposes the curated layer (~392 tools), which covers every major SOC workflow with well-described, ergonomic tools. The full generated layer (total ~1,296 tools) can be enabled with FALCON_MCP_ENABLE_GENERATED=1 for complete API surface coverage — including Message Center, ODS scans, response/content/device-control policies, installation tokens, MalQuery, FalconX Sandbox, QuickScan Pro, sample uploads, FileVantage, Falcon Complete Dashboard, cloud registration (AWS/Azure/GCP/OCI), Kubernetes admission control, container images/alerts/detections, network scanning, NGSIEM administration, knowledge bases, and much more.

Features

• EDR Telemetry — Search detections, behaviors, and incidents; drill into process execution trees and command-line activity
• Real Time Response (RTR) — Initialize RTR sessions, run read-only triage commands (ps, netstat, filehash, reg query), and execute active responder and admin commands with configurable safety gates
• Threat Intelligence — Research threat actors, query CrowdStrike indicators, retrieve MITRE ATT&CK reports, and search intelligence reports
• Custom IOC Management — Search, create, and delete custom indicators of compromise; manage IOC watchlists
• Vulnerability Management (Spotlight) — Query CVE exposure by host, filter by severity or CVE ID, and surface vulnerability assessments
• Cloud Security — Kubernetes container visibility, container image vulnerabilities, CSPM asset inventory, and serverless function vulnerability scanning
• Identity Protection (IDP) — Entity investigation and identity-based threat analysis
• MSSP / Flight Control — List and target child CIDs; pass a per-tool member_cid to scope any query to a specific managed tenant
• Next-Gen SIEM (NGSIEM) — Execute CQL queries against the Falcon NGSIEM for log-based investigation
• Host Management — Query host inventory, login history, network address history, device groups, and online state
• Firewall & Custom IOA — Search and manage firewall rules and behavioral detection rule groups
• Incident Management — Correlate incidents across hosts, update status, and annotate with investigative notes
• Scheduled Reports — List, manage, and download Falcon scheduled report outputs
• Safety Gates — Read-only mode suppresses all mutating tools at registration time; a separate destructive policy controls host containment, RTR execution, and account-level deletes

Prerequisites

• Python 3.11 or later
• CrowdStrike Falcon API credentials (Client ID and Client Secret) with appropriate scopes for the modules you intend to use

FALCON_BASE_URL	Required	API endpoint URL for your region	https://api.crowdstrike.com
FALCON_MEMBER_CID	Optional	Default child CID for MSSP Flight Control; targets all queries at that tenant	ABC123DEF456GHI789
FALCON_MCP_TRANSPORT	Optional	Transport protocol: stdio, sse, or streamable-http (default: stdio)	streamable-http
FALCON_MCP_HOST	Optional	Bind host for HTTP transports (default: 127.0.0.1)	0.0.0.0
FALCON_MCP_PORT	Optional	Bind port for HTTP transports (default: 8000)	8000
FALCON_MCP_MODULES	Optional	Comma-separated list of modules to enable; omit to enable all	detections,incidents,intel

Region base URLs:

Region	Base URL
US-1	https://api.crowdstrike.com

Claude Code Integration

HTTP mode (streamable-http) is recommended for Claude Code and other AI development environments that support persistent server connections.

Step 1 — Start the server:

FALCON_CLIENT_ID=your-client-id \
FALCON_CLIENT_SECRET=your-client-secret \
FALCON_BASE_URL=https://api.crowdstrike.com \
FALCON_MCP_TRANSPORT=streamable-http \
uv run falcon-mcp

Step 2 — Add to .claude/settings.json (project) or ~/.claude/settings.json (global):

{
  "mcpServers": {
    "falcon-mcp": {
      "type": "http",
      "url": "http://localhost:8000/mcp"
    }
  }
}

For API key-protected deployments, add the header:

{
  "mcpServers": {
    "falcon-mcp": {
      "type": "http",
      "url": "http://localhost:8000/mcp",
      "headers": {
        "x-api-key": "your-api-key"
      }
    }
  }
}

Claude Desktop Integration

Stdio mode works best for Claude Desktop. Credentials are passed directly in the MCP server configuration.

{
  "mcpServers": {
    "falcon-mcp": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/rijul170/falcon-mcp", "falcon-mcp"],
      "env": {
        "FALCON_CLIENT_ID": "your-client-id",
        "FALCON_CLIENT_SECRET": "your-client-secret",
        "FALCON_BASE_URL": "https://api.crowdstrike.com"
      }
    }
  }
}

To load credentials from a .env file instead of embedding them in the config:

{
  "mcpServers": {
    "falcon-mcp": {
      "command": "uvx",
      "args": ["--env-file", "/path/to/.env", "--from", "git+https://github.com/rijul170/falcon-mcp", "falcon-mcp"]
    }
  }
}

Docker

Build the image locally from the included Dockerfile:

git clone https://github.com/rijul170/falcon-mcp.git
cd falcon-mcp
docker build -t falcon-mcp-extended .

# Run with a .env file (stdio transport)
docker run -i --rm --env-file /path/to/.env falcon-mcp-extended

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

MSSP / Multi-Tenant Usage

The server has first-class support for CrowdStrike Flight Control environments.

Default tenant targeting: Set FALCON_MEMBER_CID to route all queries to a specific child CID without changing anything else:

export FALCON_MEMBER_CID="CHILD_CID_HERE"

Per-request tenant targeting: Every tool that accepts a member_cid parameter can override the default at call time. This lets an AI agent query multiple child tenants in a single session without restarting the server:

"Search for critical detections in tenant ABC123 and compare with tenant XYZ789."

Flight Control module: The flight_control module provides tools to enumerate all child accounts, list CID groups and user groups, query MSSP role assignments, and manage group membership.

MSSP API scopes: The parent CID must have Flight Control API scopes enabled. Child CID API keys are not required when querying through the parent.

SOC Quick Start

Once the server is running and connected to Claude, you can start investigating immediately. Example prompts:

Triage new detections:

"Search for new critical and high severity detections from the last 24 hours and summarize the top 5."

Investigate a specific detection:

"Get the full process tree and command-line details for detection ID abc123."

Contain a compromised host:

"Contain host WORKSTATION-42 and add it to the IR-2025-001 tagging group."

Hunt by IOC:

"Which hosts in my environment have executed the hash d41d8cd98f00b204e9800998ecf8427e? Show me the timeline."

MSSP cross-tenant alert summary:

"List all open critical alerts across child tenants ABC123 and XYZ789 and flag any that share the same technique."

Vulnerability prioritization:

"Show me all critical CVEs with a CVSS score above 9.0 affecting internet-facing hosts."

macOS Persistence (launchd)

To run the server as a persistent background service on macOS, an example launchd plist is provided in the examples/launchd/ directory. See the template and configuration notes there.

Security Considerations

Read-only mode: For environments where write access is not required, set FALCON_MCP_READONLY=true. This suppresses all mutating tools at registration time — they are never exposed to the AI agent, regardless of what is asked.

Destructive operation gating: Even with writes enabled, tools annotated as destructive (host containment, RTR command execution, account-level deletes) are suppressed by default. Enable them explicitly via FALCON_MCP_ALLOW_DESTRUCTIVE. The recommended approach is to specify a comma-separated list of specific tool names rather than setting true (which arms all ~119 destructive tools):

# Enable only host containment and RTR active responder
FALCON_MCP_ALLOW_DESTRUCTIVE=falcon_perform_host_action,falcon_batch_execute_active_responder_command

API credential scoping: Create a dedicated Falcon API client for this server with only the scopes required for your use case. Do not reuse admin-level API keys. Each tool's docstring documents its required API scope.

Credential storage: Never embed API credentials in MCP configuration files committed to source control. Use environment variables, a .env file outside the repository root, or a secrets manager. For HTTP transports shared across users, enable FALCON_MCP_API_KEY to require authentication at the MCP layer in addition to Falcon API authentication.

Network exposure: The default HTTP bind address is 127.0.0.1. Do not bind to 0.0.0.0 in untrusted network environments without enabling API key authentication.
