@striderlabs/mcp-hertz

A Model Context Protocol (MCP) connector for the Hertz car rental service. This connector enables AI assistants (such as Claude) to search for vehicles, manage reservations, look up locations, retrieve rental policies, and check Gold Plus Rewards loyalty status — all through Hertz's website via headless browser automation.

Overview

This connector uses Playwright to drive a headless Chromium browser against hertz.com. It exposes 10 MCP tools that cover the full car rental workflow:

• Search available vehicles
• Get detailed vehicle and rate information
• Find nearby Hertz locations
• Create, view, modify, and cancel reservations
• Retrieve rental policies and insurance options
• Add optional extras (GPS, child seats, etc.)
• Check Gold Plus Rewards loyalty status

Prerequisites

• Node.js 18 or higher
• npm 9 or higher
• Internet access to reach hertz.com

Installation

From the package directory

npm install
npx playwright install chromium
npm run build

As a global CLI

npm install -g @striderlabs/mcp-hertz
npx playwright install chromium

Configuration

No API keys or environment variables are required. The connector uses public-facing Hertz web pages. Network access to https://www.hertz.com must be available from the host running the connector.

Optional environment variables that may influence Playwright behavior:

Running the Server

# Development (TypeScript source)
npm run dev

# Production (compiled)
npm run build
npm start

The server communicates over stdio using the MCP protocol and is designed to be launched by an MCP host such as Claude Desktop.

Claude Desktop Configuration

Add the following to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "hertz": {
      "command": "node",
      "args": ["/path/to/mcp-hertz/dist/index.js"]
    }
  }
}

Or, if installed globally:

{
  "mcpServers": {
    "hertz": {
      "command": "mcp-hertz"
    }
  }
}

Notes on Browser Automation

• The connector launches a headless Chromium browser via Playwright for each tool call and closes it upon completion.
• Playwright Chromium must be installed separately with npx playwright install chromium.
• Each tool call makes a real network request to hertz.com. Response times depend on site performance (typically 5–30 seconds).
• Hertz's website uses heavy JavaScript rendering. The connector waits for networkidle state before extracting data.
• If the live site returns no parseable DOM data (e.g. due to a site redesign or anti-bot measures), several tools fall back to structured placeholder responses so that the calling agent can continue reasoning.
• Do not use this connector to make real reservations with real payment information without understanding the full booking flow and Hertz's terms of service.
