Mapbox MCP Server

Node.js server implementing Model Context Protocol (MCP) for Mapbox APIs.

Unlock Geospatial Intelligence for Your AI Applications

The Mapbox MCP Server transforms any AI agent or application into a geospatially-aware system by providing seamless access to Mapbox's comprehensive location intelligence platform. With this server, your AI can understand and reason about places, navigate the physical world, and access rich geospatial data including:

• Global geocoding to convert addresses and place names to coordinates and vice versa
• Points of interest (POI) search across millions of businesses, landmarks, and places worldwide
• Multi-modal routing for driving, walking, and cycling with real-time traffic
• Travel time matrices to analyze accessibility and optimize logistics
• Route optimization to find the optimal visiting order for multiple stops (traveling salesman problem)
• Map matching to snap GPS traces to the road network for clean route visualization
• Isochrone generation to visualize areas reachable within specific time or distance constraints
• Static map images to create visual representations of locations, routes, and geographic data
• Offline geospatial calculations for distance, area, bearing, buffers, and spatial analysis without requiring API calls

Whether you're building an AI travel assistant, logistics optimizer, location-based recommender, or any application that needs to understand "where", the Mapbox MCP Server provides the spatial intelligence to make it possible. You can also enable it on popular clients like Claude Desktop and VS Code. See below for details

Resources

The MCP server exposes static reference data as MCP resources. Resources provide read-only access to data that clients can reference directly without making tool calls.

Available Resources

Mapbox Categories Resource

URI Pattern: mapbox://categories or mapbox://categories/{language}

Access the complete list of available category IDs for use with the category search tool. Categories can be used to filter search results by type (e.g., "restaurant", "hotel", "gas_station").

Examples:

• mapbox://categories - Default (English) category list
• mapbox://categories/ja - Japanese category names
• mapbox://categories/es - Spanish category names

Accessing Resources:

• Clients with native MCP resource support: Use the resources/read MCP protocol method
• Clients without resource support: Use the resource_reader_tool with the resource URI

Rich Map Previews (MCP Apps)

The static_map_image_tool provides an interactive map preview panel in compatible clients, in addition to the base64 image that all clients receive.

This server implements the MCP Apps protocol (@modelcontextprotocol/ext-apps), which renders a self-contained HTML app panel directly inside the chat. Supported clients show an interactive map with a Fullscreen toggle:

• Claude Desktop ✅
• VS Code with GitHub Copilot ✅
• Claude Code ✅
• Goose ✅

All clients receive the base64-encoded map image regardless of protocol support — interactive previews are a progressive enhancement on top of the standard image response.

Legacy: MCP-UI

This server also retains support for MCP-UI (@mcp-ui/server), an earlier open specification for embedded iframe previews. MCP Apps is the recommended protocol; MCP-UI support is kept for backwards compatibility.

MCP-UI is enabled by default. To disable it, pass --disable-mcp-ui as a command-line flag or set ENABLE_MCP_UI=false. See the MCP-UI documentation for details.

CLIENT_NEEDS_RESOURCE_FALLBACK

Resource Fallback Tools (Opt-In for Non-Compliant Clients)

Resources are a core MCP feature supported by most clients (Claude Desktop, VS Code, MCP Inspector, etc.). However, some clients (like smolagents) don't support resources at all. For these clients, the server can provide "resource fallback tools" that deliver the same content as resources but via tool calls.

Fallback Tools:

• resource_reader_tool - Generic fallback for reading any resource by URI
• category_list_tool - Provides access to category list (mapbox://categories)

By default, these tools are NOT included (assumes your client supports resources). If your client doesn't support resources, enable the fallback tools:

export CLIENT_NEEDS_RESOURCE_FALLBACK=true

When to set this:

• ✅ Set to true if using smolagents or other clients without resource support
• ❌ Leave unset (default) if using Claude Desktop, VS Code, MCP Inspector, or any resource-capable client
• ❌ Leave unset if unsure (most clients support resources)

Tools

Utility Tools

Resource Reader Tool

Provides access to MCP resources for clients that don't support the native MCP resource API. Use this tool to read resources like the category list.

Parameters:

• uri: The resource URI to read (e.g., mapbox://categories, mapbox://categories/ja)

Example Usage:

• Read default categories: {"uri": "mapbox://categories"}
• Read Japanese categories: {"uri": "mapbox://categories/ja"}

Note: If your MCP client supports native resources, prefer using the resource API directly for better performance.

Development

Inspecting server

Using Node.js

# Run the built image
npm run inspect:build

Using Docker

# Build the Docker image
docker build -t mapbox-mcp-server .

# Run and inspect the server
npx @modelcontextprotocol/inspector docker run -i --rm --env MAPBOX_ACCESS_TOKEN="YOUR_TOKEN" mapbox-mcp-server

Create new tool

npx plop create-tool
# provide tool name without suffix (e.g. Search)

Releasing a New Version

# 1. Bump version in package.json
npm version <new-version> --no-git-tag-version

# 2. Sync version to manifest.json and server.json
npm run sync-manifest

# 3. Prepare CHANGELOG (replaces "Unreleased" with version and date)
npm run changelog:prepare-release <new-version>

# 4. Update package-lock.json
npm install

# 5. Review changes, then commit and tag
git add package.json package-lock.json manifest.json server.json CHANGELOG.md
git commit -m "Release v<new-version>"
git tag v<new-version>
git push && git push --tags

Important: The publisher workflow validates that package.json and server.json versions match the release version. Skipping the version bump or manifest sync will cause publish failures.
