At the BUILD with Mapbox 2025 event, Ian Ward and Jussi Salminen showcased the Mapbox DevKit Model Context Protocol (MCP) Server, which streamlines development by enabling coding agents to efficiently handle tasks such as map styling and token management. The DevKit MCP Server, available in both hosted and local versions, facilitates integration with AI coding tools, reducing manual steps and accelerating workflows through natural language prompts. This open standard enhances AI applications by providing direct access to Mapbox's geospatial services without extra integration code. Built with a TypeScript foundation and a modular tool hierarchy, the server ensures reliability and ease of use, supporting developers with tools like Anthropic's Claude Code and OpenAI's Codex. The session highlighted how the DevKit MCP aids in creating custom map styles, comparing map styles, initializing web maps, and visualizing GeoJSON data, ultimately aiming to enhance the developer experience and increase productivity when working with Mapbox's location platform.
