Sketch integrated a built-in MCP (Model Context Protocol) server into its Mac app, allowing users to connect external AI coding agents — such as Claude Code, Cursor, or Codex — directly to their open design documents to automate tasks like exporting assets, renaming layers, swapping symbols, and generating placeholder content.

Released in October 2025 with Sketch version 2025.2.4, the MCP server exposes two core tools: get_selection_as_image, which captures a screenshot of the user's current canvas selection and returns it to the AI client for analysis, and run_code, which lets the AI write and execute SketchAPI scripts to manipulate design files programmatically. The server is local-only, off by default, and cannot be accessed remotely — all processing happens on the user's machine. Users must actively start the server from the Command Bar. Sketch also published a skills repository, including the 'sketch-implement-design' skill, which guides compatible AI agents through a structured workflow to convert Sketch frames into working frontend code.
