Google Maps Platform Maps Grounding Essentials Toolkit
+*Alpha version*
+
+## Description
+
+The Google Maps Platform Maps Grounding Essentials toolkit is a Model Context Protocol (MCP) server that provides essential Google Maps Platform functionalities, such as Places Search, Route Computation, and Weather Lookup. This toolkit enhances the responses from large language models (LLMs) used for developing applications with the Google Maps Platform by giving them direct access to these functionalities.
+
+Since the MCP server accesses the content when the model is prompted, the LLM's context regarding Google Maps Platform does not have to be limited to the available data at the model's training date.
+
+## 🔧 Tools Provided
+
+The MCP server exposes the following tools for AI clients:
+
+ 1. **`GoogleMapsPlatformWeatherLookup`**: Provides current conditions, hourly, and daily forecasts for any location.
+ 2. **`GoogleMapsPlatformPlacesSearchText`**: Searches for places using a text query.
+ 3. **`GoogleMapsPlatformComputeRoutes`**: Computes a travel route between a specified origin and destination.
+
+-----
+
+## 🛠️ Supported MCP Transports
+
+This server supports the following standard MCP communication protocol:
+
+ * **`stdio`**: This is the default transport used when a client invokes the server via a `command`. It communicates over the standard input/output streams, making it ideal for local command-line execution.
+
+-----
+
+## 🚀 Usage
+
+You can run the Maps Grounding Essentials MCP server on your local development machine.
+
+### Requirements
+
+In order to use the Google Maps Platform Maps Grounding Essentials toolkit, you need an environment with [Node.js](https://nodejs.org/en/download/) (LTS version recommended) and npm installed in order to clone and run the server, as well as an MCP client to access the server.
+
+### Use Maps Grounding Essentials as a Local MCP Server with `stdio` transport (Recommended)
+
+Run the server on your local machine and connect clients using `stdio` protocol for use with AI-assisted IDEs (like VS Code, Android Studio, Cursor) or desktop AI applications (like Gemini CLI). This is the simplest and most common setup.
+
+#### Configure Your Client
+
+Add the server to your preferred AI client's MCP configuration file. Find your client below for specific, verified instructions.
+
+1. **[Gemini Code Assist & Gemini CLI](https://developers.google.com/gemini-code-assist/docs/use-agentic-chat-pair-programmer#configure-mcp-servers)**
+ * Option 1 - Add the server directly from your command line (assuming you have Gemini CLI already installed):
+ ```bash
+ gemini mcp add google-maps-platform-maps-tool npx -y @googlemaps/maps-grounding-essentials-mcp@latest
+ ```
+ * Verify the installation by running `gemini mcp list`.
+ * Option 2 - Add the MCP server config manually to your `~/.gemini/settings.json` file.
+ ```json
+ {
+ "mcpServers": {
+ "google-maps-platform-maps-tool": {
+ "command": "npx",
+ "args": ["-y", "@googlemaps/maps-grounding-essentials-mcp@latest"],
+ "env": {
+ "GOOGLE_MAPS_API_KEY": "YOUR_API_KEY"
+ }
+ }
+ }
+ }
+ ```
+
+2. **[Claude Code](https://docs.anthropic.com/en/docs/claude-code/mcp)**
+ * Option 1 - Add the server directly from your command line (assuming you have Claude Code already installed):
+ ```bash
+ claude mcp add google-maps-platform-maps-tool -- npx -y @googlemaps/maps-grounding-essentials-mcp@latest
+ ```
+ * Verify the installation by running `claude mcp list`.
+ * **Windows Users:** On native Windows (not WSL), you must use the `cmd /c` wrapper for `npx` commands to work correctly.
+ ```bash
+ claude mcp add google-maps-platform-maps-tool -- cmd /c "npx -y @googlemaps/maps-grounding-essentials-mcp@latest"
+ ```
+ * Option 2 - Add the sever manually to your Claude config file `~/.claude.json`
+ ```json
+ "mcpServers": {
+ "google-maps-platform-maps-tool": {
+ "command": "npx",
+ "args": [
+ "-y", "@googlemaps/maps-grounding-essentials-mcp@latest"
+ ],
+ "env": {
+ "GOOGLE_MAPS_API_KEY": "YOUR_API_KEY"
+ }
+ }
+ }
+ ```
+
+3. **[Cursor](https://docs.cursor.com/en/context/mcp)**
+ * [](https://cursor.com/en/install-mcp?name=google-maps-platform&config=eyJjb21tYW5kIjoibnB4IC15IEBnb29nbGVtYXBzL21hcHMtZ3JvdW5kaW5nLWVzc2VudGlhbHMtbWNwIn0) <-- If you already have Cursor installed, click here to install Google Maps Platform Maps Grounding Essentials MCP directly.
+ * Otherwise, add it to your workspace's `.cursor-settings/mcp.json` file.
+ ```json
+ {
+ "mcpServers": {
+ "google-maps-platform-maps-tool": {
+ "command": "npx",
+ "args": ["-y", "@googlemaps/maps-grounding-essentials-mcp@latest"],
+ "env": {
+ "GOOGLE_MAPS_API_KEY": "YOUR_API_KEY"
+ }
+ }
+ }
+ }
+ ```
+
+4. **[Firebase Studio](https://firebase.google.com/docs/studio/customize-workspace)**
+ * with Maps Grounding Essentials MCP installed
+ * Add to your project's `mcp.json` file in the `.idx` folder in your Firebase Studio workspace
+ ```json
+ {
+ "mcpServers": {
+ "google-maps-platform-maps-tool": {
+ "command": "npx",
+ "args": ["-y", "@googlemaps/maps-grounding-essentials-mcp@latest"],
+ "env": {
+ "GOOGLE_MAPS_API_KEY": "YOUR_API_KEY"
+ }
+ }
+ }
+ }
+ ```
+
+5. **[Android Studio](https://developer.android.com/studio/gemini/add-mcp-server)**
+ * Create a `mcp.json` file and place it in the [configuration directory](https://developer.android.com/studio/troubleshoot#directories) of Android Studio. Add the Maps Grounding Essentials server to the list:
+ ```json
+ {
+ "mcpServers": {
+ "google-maps-platform-maps-tool": {
+ "command": "npx",
+ "args": ["-y", "@googlemaps/maps-grounding-essentials-mcp@latest"],
+ "env": {
+ "GOOGLE_MAPS_API_KEY": "YOUR_API_KEY"
+ }
+ }
+ }
+ }
+ ```
