Devkit Server MCP Server

Mapbox Developer MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with direct access to Mapbox developer APIs. This server enables AI models to interact with Mapbox services, helping developers build Mapbox applications more efficiently.

Looking for Mapbox documentation access? Use mcp-docs-server alongside this server — it provides AI assistants with access to Mapbox documentation, guides, and API references from docs.mapbox.com.

Quick Start

Integration with Developer Tools

Get started by integrating with your preferred AI development environment:

• Claude Code Integration - Command-line development with Claude
• Claude Desktop Integration - Desktop application integration
• Cursor Integration - Cursor IDE integration
• VS Code Integration - Visual Studio Code with GitHub Copilot

DXT Package Distribution

This MCP server can be packaged as a DXT (Desktop Extension) file for easy distribution and installation. DXT is a standardized format for distributing local MCP servers, similar to browser extensions.

Creating the DXT Package

To create a DXT package:

# Install the DXT CLI tool
npm install -g @anthropic-ai/dxt

# Build the server first
npm run build

# Create the DXT package
npx @anthropic-ai/dxt pack

This will generate mcp-devkit-server.dxt using the configuration in manifest.json.

The DXT package includes:

• Pre-built server code (dist/esm/index.js)
• Server metadata and configuration
• User configuration schema for the Mapbox access token
• Automatic environment variable setup

Hosted MCP Endpoint

For quick access, you can use our hosted MCP endpoint:

Endpoint: https://mcp-devkit.mapbox.com/mcp

For detailed setup instructions for different clients and API usage, see the Hosted MCP Server Guide. Note: This guide references the standard MCP endpoint - you'll need to update the endpoint URL to use the devkit endpoint above.

Getting Your Mapbox Access Token

A Mapbox access token is required to use this MCP server.

1. Sign up for a free Mapbox account at mapbox.com/signup
2. Navigate to your Account page
3. Create a new token with the required scopes for your use case

For more information about Mapbox access tokens, see the Mapbox documentation on access tokens.

⚠️ IMPORTANT: Token Privileges Required

The MAPBOX_ACCESS_TOKEN environment variable is required. Each tool requires specific token scopes/privileges to function properly. For example:

• Reading styles requires styles:read scope
• Creating styles requires styles:write scope
• Managing tokens requires tokens:read and tokens:write scopes
• Accessing feedback requires user-feedback:read scope

Tools

Reference Tools

Reference data is exposed as MCP Resources (see Resources section). MCP clients that support the resources protocol can access them directly.

Available References:

• resource://mapbox-style-layers - Mapbox GL JS style specification reference guide covering all layer types (fill, line, symbol, circle, fill-extrusion) and their properties
• resource://mapbox-streets-v8-fields - Complete field definitions for all Mapbox Streets v8 source layers, including enumerated values for each field (useful for building filters)
• resource://mapbox-token-scopes - Comprehensive token scope reference explaining what each scope allows and which scopes are needed for different operations
• resource://mapbox-layer-type-mapping - Mapping of Mapbox Streets v8 source layers to compatible GL JS layer types, with common usage patterns

Example prompts:

• "What fields are available for the landuse layer?"
• "Show me the token scopes reference"
• "What layer type should I use for roads?"
• "Get the Streets v8 fields reference"
• "What scopes do I need to display a map?"

Local Processing Tools

GeoJSON Preview tool (Beta)

Generate a geojson.io URL to visualize GeoJSON data. This tool:

• Validates GeoJSON format (Point, LineString, Polygon, Feature, FeatureCollection, etc.)

design-data-driven-style

Create a map style with data-driven properties that respond dynamically to feature data using expressions.

Arguments:

• style_name (required): Name for the data-driven style
• data_description (required): Description of the data (e.g., "population by city", "earthquake magnitudes")
• property_name (required): Name of the data property to visualize (e.g., "population", "magnitude")
• visualization_type (optional): How to visualize: "color", "size", "both", "heatmap" (default: "color")
• color_scheme (optional): Color scheme: "sequential", "diverging", "categorical" (default: "sequential")

What it does:

1. Explains data-driven styling concepts and expressions
2. Provides appropriate expression templates for your use case
3. Offers color scales and size ranges based on visualization type
4. Creates the style with data-driven layers
5. Includes advanced expression examples (zoom-based, conditional)
6. Provides best practices for accessibility and performance

Example usage:

Use prompt: design-data-driven-style
Arguments:
  style_name: "Population Density Map"
  data_description: "City population data"
  property_name: "population"
  visualization_type: "both"
  color_scheme: "sequential"

prepare-style-for-production

Comprehensive quality validation workflow for Mapbox styles before production deployment.

Arguments:

• style_id_or_json (required): Either a Mapbox style ID or complete style JSON
• skip_optimization (optional): Set to "true" to skip style optimization (default: false)
• wcag_level (optional): WCAG compliance level: "AA" or "AAA" (default: "AA")

What it does:

1. Loads the style (retrieves from Mapbox or parses JSON)
2. Validates all expressions (filters, paint properties, layout properties)
3. Validates GeoJSON sources for coordinate and structure errors
4. Checks color contrast for text layers (WCAG compliance)
5. Optimizes the style (removes redundancies, simplifies expressions)
6. Generates a comprehensive quality report with deployment readiness assessment

Example usage:

Use prompt: prepare-style-for-production
Arguments:
  style_id_or_json: "username/my-style-id"
  wcag_level: "AA"
  skip_optimization: "false"

Resources

This server exposes static reference documentation as MCP Resources. MCP clients that support the resources protocol can access them directly.

Available Resources:

1. Mapbox Style Specification Guide (resource://mapbox-style-layers)

   • Complete reference for Mapbox GL JS layer types and properties
   • Covers fill, line, symbol, circle, and fill-extrusion layers
   • Includes paint and layout properties for each layer type

2. Mapbox Streets v8 Fields Reference (resource://mapbox-streets-v8-fields)

   • Field definitions for all Streets v8 source layers
   • Enumerated values for filterable fields
   • Essential for building accurate style filters
   • Example: landuse layer has class field with values like park, cemetery, hospital, etc.

3. Mapbox Token Scopes Reference (resource://mapbox-token-scopes)

   • Comprehensive documentation of token scopes
   • Explains public vs. secret token scopes
   • Common scope combinations for different use cases
   • Best practices for token management

4. Mapbox Layer Type Mapping (resource://mapbox-layer-type-mapping)

   • Maps Streets v8 source layers to compatible GL JS layer types
   • Organized by geometry type (polygon, line, point)
   • Includes common usage patterns and examples
   • Helps avoid incompatible layer type/source layer combinations

Note: Resources provide static reference data that doesn't change frequently, while tools provide dynamic, user-specific data (like listing your styles or tokens) and perform actions (like creating styles or tokens).

Observability & Tracing

This server includes comprehensive distributed tracing using OpenTelemetry (OTEL) for production-ready observability.

Features

• Opt-in Configuration: Tracing is disabled by default, enabling it requires only setting an OTLP endpoint
• Tool Execution Tracing: Automatic instrumentation of all tool executions with timing, success/failure status, and error details
• HTTP Request Instrumentation: Complete request/response tracing for Mapbox API calls with CloudFront correlation IDs
• Configuration Tracing: Startup configuration loading with error tracking
• Security: Input/output sizes logged but content is protected
• Low Overhead: <1% CPU impact, ~10MB memory for trace buffers

Quick Start with Jaeger

# 1. Start Jaeger (Docker required)
npm run tracing:jaeger:start

# 2. Configure environment
cp .env.example .env
# Edit .env to add MAPBOX_ACCESS_TOKEN
# OTEL_EXPORTER_OTLP_ENDPOINT is already set to http://localhost:4318

# 3. Run the server
npm run inspect:build

# 4. View traces at http://localhost:16686

# 5. Stop Jaeger when done
npm run tracing:jaeger:stop
