Security Notice

Keeping local deployments of the TomTom MCP Server up-to-date is the responsibility of the MCP client/operator. TomTom publishes updates to address known vulnerabilities, but failing to apply updates, patches, or recommended security configurations to your local instance may expose it to known vulnerabilities.

Quick Start

Prerequisites

• Node.js 22.x (strict requirement for dynamic map tool, other tools may work with older/newer versions)
• TomTom API key
• OS-level dependencies for MapLibre GL Native:
  • macOS:

    # Install required dependencies via Homebrew
    brew install webp libuv icu4c jpeg-turbo glfw
    brew link icu4c --force
    

  • Ubuntu/Debian:

    # Install essential dependencies for MapLibre Native rendering
    sudo apt-get install -y libcurl4-openssl-dev libglfw3-dev libuv1-dev \
      libicu-dev libpng-dev libjpeg-turbo8-dev libwebp-dev
    

  • Windows: Choose one of the two options:
    • Using Visual Studio:
      • Install Visual Studio 2022 with "Desktop Development with C++"
    • Using MSYS2:
      • Install MSYS2, then run:

        pacman -S --needed mingw-w64-x86_64-angleproject mingw-w64-x86_64-curl-winssl \
          mingw-w64-x86_64-glfw mingw-w64-x86_64-icu mingw-w64-x86_64-libjpeg-turbo \
          mingw-w64-x86_64-libpng mingw-w64-x86_64-libwebp mingw-w64-x86_64-libuv
        

💡 Note: For any issues with native dependencies or the dynamic map tool, please refer to the Troubleshooting section.

How to obtain a TomTom API key:

1. Create a developer account on TomTom Developer Portal and Sign-in
2. Go to API & SDK Keys in the left-hand menu.
3. Click the red Create Key button.
4. Select all available APIs to ensure full access, assign a name to your key, and click Create.

For more details, visit the TomTom API Key Management Documentation.

Installation

npm install @tomtom-org/tomtom-mcp@latest

# or run directly without installing
npx @tomtom-org/tomtom-mcp@latest

---

Configuration

Set your TomTom API key using one of the following methods:

# Option 1: Use a .env file (recommended)
echo "TOMTOM_API_KEY=your_api_key" > .env

# Option 2: Environment variable
export TOMTOM_API_KEY=your_api_key

# option 3: Pass as CLI argument
npx @tomtom-org/tomtom-mcp@latest

Environment Variables

| Variable | Description | Default | |----------|-------------|---------| | TOMTOM_API_KEY | Your TomTom API key | - | | MAPS | Backend to use: tomtom-maps (TomTom Maps) or tomtom-orbis-maps (TomTom Orbis Maps) | tomtom-maps | | ENABLE_DYNAMIC_MAPS | Enable or disable the dynamic maps feature | false | | LOG_LEVEL | Logging level: debug, info, warn, or error. Use debug for local development to see all logs | info |

Note about ENABLE_DYNAMIC_MAPS:

• By default, the dynamic map tool is disabled (false) to avoid dependency issues
• Set to true to enable dynamic maps after installing required dependencies
• In Docker containers, this is set to true by default as all dependencies are pre-installed

---

Usage

Stdio Mode (Default - for AI assistants like Claude):

# Start MCP server via stdio
npx @tomtom-org/tomtom-mcp@latest

HTTP Mode (for web applications and API integration):

npm run start:http
# or after building the project
node bin/tomtom-mcp-http.js

When running in HTTP mode, you need to include your API key in the tomtom-api-key header:

tomtom-api-key: <API_KEY>

For example, to make a request using curl:

curl --location 'http://localhost:3000/mcp' \
--header 'Accept: application/json,text/event-stream' \
--header 'tomtom-api-key: <API KEY>' \
--header 'Content-Type: application/json' \
--data '{
  "method": "tools/call",
  "params": {
    "name": "tomtom-geocode",
    "arguments": {
        "query": "Amsterdam Central Station"
    }
  },
  "jsonrpc": "2.0",
  "id": 24
}'

The Docker setup is also configured to use this HTTP mode with the same authentication method.

Docker Mode (recommended):

# Option 1: Using docker run directly
# Note: TomTom Maps is the default backend (same as npm package)
docker run -p 3000:3000 ghcr.io/tomtom-international/tomtom-mcp:latest

# To use TomTom Orbis Maps backend instead:
docker run -p 3000:3000 -e MAPS=tomtom-orbis-maps ghcr.io/tomtom-international/tomtom-mcp:latest

# Option 2: Using Docker Compose (recommended for development)
# Clone the repository first
git clone https://github.com/tomtom-international/tomtom-mcp.git
cd tomtom-mcp

# Start the service (uses TomTom Maps backend by default)
docker compose up

curl --location 'http://localhost:3000/mcp' \
--header 'Accept: application/json,text/event-stream' \
--header 'tomtom-api-key: <API KEY>' \
--header 'Content-Type: application/json' \
--data '{
  "method": "tools/call",
  "params": {
    "name": "tomtom-geocode",
    "arguments": {
        "query": "Amsterdam Central Station"
    }
  },
  "jsonrpc": "2.0",
  "id": 24
}'

TomTom Orbis Maps (optional backend)

By default the MCP tools use TomTom Maps APIs listed above. We also support using TomTom Orbis Maps for the same tools. To enable TomTom Orbis Maps for all tools set the environment variable MAPS=tomtom-orbis-maps

Important: TomTom Orbis Maps tools are currently in Public Preview and require explicit enablement for developer accounts. To request access, contact TomTom Sales:

• Public Preview details: https://developer.tomtom.com/public-preview
• Contact Sales to enable TomTom Orbis Maps for your developer account

How dynamic map tool works

We fetch a Map Style JSON (either from TomTom Maps or TomTom Orbis Maps), then use MapLibre (server-side) to:

• add markers, routes, polygons and other layers defined by the style and request;
• render all layers into an image using that style.

The server converts the rendered image to PNG and returns as Base64 string.

Contributing & Local Development

Setup

git clone <repository>

cd tomtom-mcp

npm install

cp .env.example .env      # Add your API key in .env

npm run build             # Build TypeScript files

node ./bin/tomtom-mcp.js   # Start the MCP server

Testing

npm run build               # Build TypeScript
npm test                    # Run all tests
npm run test:unit           # Unit tests only
npm run test:comprehensive  # Integration tests

---

Testing Requirements

⚠️ Important: All tests require a valid API key in .env as they make real API calls (not mocked). This will consume your API quota.

Troubleshooting

Native Dependency Issues

If you encounter issues with native dependencies (especially for the dynamic map tool):

Option 1 – Check your NPM settings

If you have the ignore-scripts setting enabled (npm config get ignore-scripts returns true), some native dependencies required by NPM packages may not be installed automatically. This can cause build or runtime errors, especially for packages that rely on native modules.
Solution: Consider setting ignore-scripts to false by running:

npm config set ignore-scripts false

Option 2 – Run the MCP server via Docker

1. Run the MCP server via Docker: Our Docker image includes all required dependencies pre-configured:

   docker run -p 3000:3000 ghcr.io/tomtom-international/tomtom-mcp:latest
   
   # or with Docker Compose (recommended for development)
   docker compose up
   

2. Connect via HTTP client: Send requests to http://localhost:3000/mcp with your API key in the tomtom-api-key header.

This approach isolates all native dependencies inside the container while providing the same functionality.

Dynamic Map Tool Issues

By default, the dynamic map tool is disabled to avoid native dependency issues. To enable it:

1. Ensure Node.js 22.x: The dynamic map tool specifically requires Node.js version 22.x
2. Install required dependencies: Follow the platform-specific instructions in the Prerequisites section
3. Enable dynamic maps: Set ENABLE_DYNAMIC_MAPS=true in your environment or .env file

For detailed build instructions, see the official MapLibre Native documentation:

• macOS Build Guide
• Linux Build Guide
• Windows Build Guide (MSVC)
• Windows Build Guide (MSYS2)

API Key Issues

echo $TOMTOM_API_KEY  # Check if set

Test Failures

ls -la .env          # Verify .env exists
cat .env             # Check API key

Build Issues

npm run build            # Rebuild
npm cache clean --force  # Clear cache
