Local MCP Server

The Local MCP Server is Figma desktop's built in implementation of the Model Context Protocol that Anthropic first released in late 2024. Flip the single toggle labeled Enable local MCP server inside Figma Preferences under the Dev Mode tab and your machine starts serving Figma file data over HTTP on port 3845. AI coding agents that support MCP such as Claude Code from Anthropic and Cursor can then connect with one command and pull structured information directly from your designs. This includes the complete hierarchy of frames layers and groups with their unique IDs, all auto layout settings with exact values for gaps padding and alignment, every reference to design tokens for colors spacing and text styles, full details on component instances including overrides applied to each one, the actual text strings and their typography styles, and URLs for any image fills. Figma shipped the official server in 2025 turning what used to be screenshot only integrations into direct data access. The five minute process of enabling the toggle and running the add server command in your terminal eliminates the guesswork that has plagued design to code handoffs for years. Agents stop inventing new colors and start using the exact variables you defined. They stop approximating your button and start importing the real one from your library.

This Local MCP Server is not hosted in the cloud by Figma or any AI company. It runs entirely on your laptop which keeps sensitive files under your control but requires Figma desktop to stay running. It is not a blanket permission for AI to browse your whole team space or read comments and version history. Access stays strictly scoped to the files whose URLs you provide in each prompt. The server does not transmit prototype interactions animation settings or conditional variant logic so those elements remain outside its capabilities. It cannot peek inside plugin generated layers to understand their source data or regeneration rules. Image fills come as references only so complex photographic compositions still benefit from supplemental screenshots. Most of all it is not a cure for an immature design system. If your file relies on random pixel values instead of tokens or breaks auto layout best practices the server will report that reality accurately and the resulting code will reflect it.

Watch the Local MCP Server deliver results at real companies throughout 2026. At Vercel a product designer updating the deployment dashboard enabled the server and connected Claude Code with the terminal command claude mcp add figma http://127.0.0.1:3845/mcp --transport http. The previous screenshot based prompt produced code full of arbitrary values like p-[14px] and a custom button with made up hover states. The MCP connected prompt read the real spacing-6 token mapped to 24 pixels the surface-tertiary variable for background and the production Button component with its ghost variant already configured. The output required almost no cleanup and integrated immediately with their existing codebase. The Linear team took it further by using the server for Code Connect validation. When generating new elements for their command palette the agent cross checked against registered Code Connect mappings and avoided creating duplicate implementations of their core input components. This saved multiple engineering hours per week. At Ramp the finance platform the design ops lead ran regular token compliance checks by pointing Claude Code at batches of Figma frames. One prompt surfaced every outdated color token still lingering in checkout and settings pages weeks after the official update. These workflows turned what felt like constant alignment tax into automated accuracy. A freelance designer rebuilding Notion-style database views in mid 2026 used the same setup in Cursor to generate a responsive table that imported the exact Row and Cell components from the client's library instead of creating new div hell with guessed margins.

Fire up the Local MCP Server when you have a solid design system built with variables and components and you want AI to respect it without deviation. It pays off immediately in design to code tasks at teams using modern tools like Claude Code and Cursor. Leverage it for design QA by comparing live sites against Figma sources of truth. Activate it to speed up variable audits after system updates. It pairs perfectly with Figma Code Connect to prevent redundant code. Connect it across multiple AI applications at the same time since the local server supports concurrent access. Keep it turned off when your files are loose early concepts without proper structure because the bad input produces bad output faster. Avoid it for work covered by strict NDAs that prohibit any external model context even local ones. Do not count on it alone for projects where motion design and prototypes form the core experience since that data never reaches the agent. Stay away if you have not yet adopted auto layout across your frames or if you work primarily in Figma web where the server toggle does not exist.

Local MCP Server replaces the screenshot and hope method with direct access to your real design system making AI output useful instead of approximate on the first try.
