Huntress API MCP Server

A Model Context Protocol (MCP) server that provides tools for interacting with the Huntress API. This server enables programmatic access to Huntress functionality including account management, organization management, agent management, incident reports, and more.

Features

• Latest MCP SDK 1.15.1: Built with the latest Model Context Protocol features
• Deferred Initialization: Optimized for Smithery deployment with lazy loading
• Container Support: Ready for containerized deployment via Smithery
• HTTP/SSE Transport: Supports both stdio and HTTP/SSE modes
• CORS Enabled: Full CORS support for browser-based MCP clients
• Health Check: Built-in health check endpoint for container orchestration
• Rate Limiting: Built-in rate limiting (60 requests per minute)
• Comprehensive Error Handling: Detailed error messages and validation
• Session Management: Compatible with Smithery's tool discovery process

Installation

Installing via Smithery

To install Huntress API MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install huntress-mcp-server --client claude

Manual Installation

1. Clone the repository
2. Install dependencies:

npm install

3. Create a .env file based on .env.example:

HUNTRESS_API_KEY=your_api_key_here
HUNTRESS_API_SECRET=your_api_secret_here

4. Build the server:

npm run build

Available Tools

Account Management

• get_account_info: Get information about the current account

Organization Management

• list_organizations: List organizations in the account (supports pagination)
• get_organization: Get details of a specific organization

Agent Management

• list_agents: List agents in the account (supports pagination)
• get_agent: Get details of a specific agent

Incident Management

• list_incidents: List incidents in the account (supports pagination and status filtering)
• get_incident: Get details of a specific incident

Configuration

The server requires the following environment variables:

• HUNTRESS_API_KEY: Your Huntress API Key
• HUNTRESS_API_SECRET: Your Huntress API Secret Key

These can be obtained from your Huntress account at <your_account_subdomain>.huntress.io under API Credentials.

Usage with MCP

Local Development (stdio mode)

Add the following configuration to your MCP settings:

{
  "mcpServers": {
    "huntress": {
      "command": "node",
      "args": ["path/to/huntress-server/build/index.js"],
      "env": {
        "HUNTRESS_API_KEY": "your_api_key_here",
        "HUNTRESS_API_SECRET": "your_api_secret_here"
      }
    }
  }
}

Container/HTTP Mode

When running in container mode, the server exposes:

• HTTP Endpoint: http://localhost:3000/ (POST for MCP requests)
• SSE Endpoint: http://localhost:3000/sse (Server-Sent Events)
• Health Check: http://localhost:3000/health (GET for health status)

Rate Limiting

The server implements Huntress API's rate limiting of 60 requests per minute on a sliding window. This means:

• No more than 60 requests can be made within any 60-second period
• The window slides, so if request 1 is made at T0 and request 60 at T30, request 61 must wait until T60

Smithery Deployment

This server is optimized for deployment on Smithery using container deployment, featuring:

• Container Runtime: Uses Docker container with HTTP streaming (SSE)
• HTTP Endpoint: Implements / endpoint for MCP communication
• Environment Variable Configuration: Maps configuration to environment variables
• Deferred Initialization: Credentials are only loaded when tools are actually invoked
• Tool Discovery: Tools can be listed without requiring authentication

Smithery Configuration

The smithery.yaml uses:

• runtime: "container" for Docker container deployment
• HTTP streaming: Server-Sent Events (SSE) for real-time communication
• Environment variable mapping: Maps configuration to HUNTRESS_API_KEY and HUNTRESS_API_SECRET
• Lazy loading: Tools discoverable without authentication

Deployment Steps

1. Push to GitHub: Ensure your code is in a GitHub repository
2. Connect to Smithery: Visit https://smithery.ai and connect your GitHub
3. Deploy: Use Smithery's container deployment for automatic building

Latest MCP Features (v1.15.1)

This server leverages the latest MCP SDK features including:

• Enhanced Error Handling: Improved error validation and reporting
• CORS Support: For browser-based MCP clients
• Session Lifecycle Hooks: Better session management
• OAuth Improvements: Enhanced authentication methods
• Async Callback Support: For session initialization and cleanup
• Custom Headers: Support for custom authentication headers
• Streamable HTTP Transport: Support for HTTP/SSE transport modes
• HTTP Endpoint: /mcp endpoint with proper REST methods

HTTP Endpoint Details

When running in HTTP mode (Smithery deployment), the server exposes:

• MCP Endpoint: http://localhost:3000/mcp
  • GET: Returns server capabilities for tool discovery
  • POST: Handles MCP tool calls
  • DELETE: Handles session cleanup
• Health Check: http://localhost:3000/health
• Configuration: Via query parameters (?huntressApiKey=xxx&huntressApiSecret=yyy)

Docker Support (Legacy)

For custom container deployment:

Build Docker Image

docker build -t huntress-mcp-server .

Run Docker Container

docker run -p 3000:3000 \
  -e HUNTRESS_API_KEY=your_api_key_here \
  -e HUNTRESS_API_SECRET=your_api_secret_here \
  huntress-mcp-server

Error Handling

The server handles various error scenarios:

• Invalid API credentials
• Rate limit exceeded
• Invalid request parameters
• API response errors
• Session management errors
• Tool discovery failures
• Container health issues
