About
Figwright connects an MCP server to a Figma plugin over a local WebSocket relay, so an AI agent (Claude Code, Cursor, Codex, or any other MCP client) can work with Figma instead of just looking at it.
It works in both directions:
Read: turn a Figma selection into framework-aware code, grounded on faithful, de-duplicated design context (layout, typography, variables, components).
Write: author and edit the canvas directly, from frames and text to auto-layout, styles, variables, components, whole screens.
Everything runs on your machine: the server, the relay, and the plugin. Your designs are never sent anywhere.
Why Figwright
- Not gated: the official Dev Mode MCP is behind a paid Dev Mode seat. Figwright runs on the free tier.
- Bidirectional: not read-only. 113 tools span reading and writing the canvas, so an agent can both implement designs and build them.
- Provider-first codegen: Figwright detects your real stack (framework + styling system) and reuses your existing components, tokens, and icons, instead of emitting generic markup you have to rewrite.
- Open & extensible: the read/write workflows ship as installable skills you can adopt or fork.
Setup
You need an MCP client (Claude Code, Cursor, …), Node.js 20.19+ or 22.12+, and Figma. The free Figma tier is enough, though the desktop app is needed to import the plugin. The server runs via npx as its own process, so its Node version is independent of the one your project builds with; Node 18/21 and 22.0–22.11 are not supported.
1. Add the server to your MCP client
For Claude Code, add this to your .mcp.json (other clients use the same shape):
npx fetches and runs the published server, so no global install is needed.
2. Install the Figma plugin
The plugin isn't on the Figma Community marketplace yet, so install it from the latest release:
- Download the plugin zip from the latest GitHub Release and unzip it.
- In the Figma desktop app: Menu → Plugins → Development → Import plugin from manifest… and pick the unzipped
manifest.json.
3. Connect
Open the Figwright plugin in Figma (Plugins → Development → Figwright). It connects to the local server automatically and shows Connected. Ask your agent to run ping to confirm the link.
4. (Optional) Install the skills
The skills make agents reach for Figwright at the right moment and follow the grounded workflows:
5. Try it
With a frame selected in Figma, prompt your agent:
Code this Figma selection as a React component.
or, the other direction:
Build a pricing section in Figma from this spec.
Skills
Agent skills orchestrate Figwright's tools. They are model-invoked: your agent loads one automatically when the task matches its description.
| Skill | What it does |
|---|---|
figma‑codegen | Turn a Figma selection into framework-aware code, grounded on your stack and existing components. |
figma‑build | Build a Figma design from code or a description, reusing the file's existing components and styles. |
Install across any supported agent with the skills CLI:
[!NOTE] Skills need the
@figwright/mcpserver connected. On their own they have no tools to drive.
Tools
Figwright exposes 113 MCP tools in three groups:
- Read: selection, document and node inspection, styles, variables, components, fonts, reactions, motion (animation) state, screenshots, original image-fill assets, PDF export, and video export of animated frames (MP4 / GIF / WebM); plus
list_files/use_filefor working across more than one open Figma file at once. - Write: create and edit frames, text, shapes, auto-layout, effects, styles, variables, components (including authoring their boolean/text/instance-swap properties), pages, reactions, and Motion animations (keyframes, animation-style presets, timelines); plus a
batchtool to apply many edits at once. - Grounding:
get_design_contextfor faithful, de-duplicated design context, andcomponent_map/token_map/icon_map, which join Figma data to your codebase so codegen reuses what you already have; plusdesign_diff, which reports what changed in a design against a saved baseline so you update only the affected code.
[!TIP] Your MCP client lists every tool at connect time, which is always the authoritative, up-to-date catalog.
Plugin
The Figma-side plugin isn't a black box. It shows every call as it happens, lets you inspect the exact payload sent to the model, and surfaces its own connection health.
Activity: every call, with timing and a jump to the nodes it touched · Payload: exactly what the model received · Debug: health, versions, and a one-click diagnostic bundle
And it follows your Figma theme, light or dark.
The window is yours to arrange. Drag the bottom-right corner to resize it. A taller panel keeps more of the log in view, and the size is remembered next time you open it. Or send it to the background: the panel gets out of your way while the connection stays live, so a long-running agent keeps working.
Resize: drag the corner, the size sticks · Background: the panel hides, the relay stays connected
How it works
Your MCP client talks to the @figwright/mcp server over stdio; the server relays to the Figma plugin over a local WebSocket. Several clients can share one plugin (they elect a leader that owns the connection), and the transport is built to ride out dropped sockets:
By design Figwright is provider-first: rather than a fixed compiler pipeline, the tools surface honest design context and let the model generate code that matches your codebase. The figma-codegen skill encodes this approach.
Security
Figwright runs entirely on your machine: your client launches the server over stdio, the server relays to the plugin over a WebSocket on 127.0.0.1:3055, and nothing is sent anywhere else. The plugin uses only Figma's public Plugin API, so it reaches the file you have open and nothing beyond it.
Loopback is not on its own a boundary, since a web page you visit can still reach a local port, so the relay gates every request on two headers a page cannot forge: Host, which must name loopback (this is what stops DNS rebinding), and Origin, which admits the plugin's sandboxed handshake and refuses browsers everywhere else. The leader's HTTP endpoints additionally require a media type that cannot be sent without a CORS preflight. See MCP Security Best Practices for the wider picture, and SECURITY.md for Figwright's threat model, what is in and out of scope, and how to report a vulnerability privately.
Figwright is not a substitute for reviewing what your agent does. Its write tools change your Figma file and its export tools write files to paths the agent chooses; an agent acting on a malicious design or a prompt-injected instruction can misuse both. Your MCP client's tool-approval controls are the boundary that matters.
FAQ
The server won't start: command not found, or it fails / disconnects with -32000 ("Connection closed").
Both come down to how your MCP client launches the server: it spawns the command directly, not through your interactive shell, so it inherits none of what your shell sets up. That bites hardest when Node is managed by a version manager (fnm, nvm, asdf, volta, mise), since those configure PATH and npm from shell hooks that only run in a real terminal. It is not specific to Figwright; it affects any npx-launched MCP server. There are two symptoms, with two different fixes.
command not found: the client can't find npx / node on its PATH.
-
Use an absolute path. In a normal terminal run
which npx(orwhich node) and use that full path ascommand: -
Or pass
PATHthroughenv. If your client supports a per-serverenv, add your version manager'sbindirectory toenv.PATH.
-32000 / "Connection closed" / it just never connects: npx runs, but the server exits before the handshake.
npx … @latest re-resolves the package from the registry on every launch. In a directly-spawned environment that step can fail or stall (empty or different npm config, a corporate proxy or private registry that is not configured there, or no network), so the process dies before MCP connects and the client reports the connection as closed. (A missing node for the binary's shebang lands here too.)
The fix is to install the package so launch needs no registry fetch:
-
As a project dependency, the quickest unblock. Install it, then drop
@latestfrom your config. The@latesttag is what forces the registry round-trip; without it,npxuses the copy already innode_modules(a project-scoped config like Claude Code's.mcp.jsonruns from your project root): -
Or globally, pinned to the binary. Install once, then point
commandstraight at it, with nonpxand no per-launch resolution. Use the absolute path fromwhich figwright-mcp:
The plugin stays on "Waiting" and never connects.
The server is launched by your MCP client, so it only runs while that client is open. Check that:
- your MCP client is running and has Figwright configured (try a
ping); - the plugin is open in the same Figma app on the same machine (the relay is local-only,
127.0.0.1); - nothing is blocking local loopback connections (some firewall / security tools do).
Do I need a paid Figma plan or Dev Mode?
No. Figwright talks to Figma through a plugin, so the free tier is enough. No Dev Mode seat or paid tier required.
Does it work in Dev Mode and FigJam?
It runs in both, with less available than in Figma Design, because those editors give plugins less rather than because Figwright holds anything back.
- Figma Design: everything.
- Dev Mode (Inspect panel): reads and exports only. Figma makes plugins read-only there, so screenshots, PDF export and every inspection tool work, while every write fails: nodes, pages, variables and styles alike. That suits the codegen direction; use Design mode to build.
- FigJam: frames, sections, shapes and text work; components, variables, styles and Motion don't exist in that editor, so the tools for them don't apply.
get_metadata reports the editor (editorType / mode), and any tool that fails because of the editor says so in its error, so an agent can re-plan rather than retry.
Can more than one agent use the same plugin at once?
Yes. Several MCP servers can share a single plugin via leader/follower election: one leads, the others follow, with a graceful handoff if the leader goes away.
Can two agents work on two different Figma files at the same time?
Yes, once each agent claims its file.
By default calls follow whichever file you last touched, so switching tabs switches what the agent sees — the right behaviour for one agent, and the wrong one for two, since the agent whose file isn't in front would silently get the other file's nodes. Whenever more than one file is open and an agent hasn't claimed one, every result it gets says so, so it can claim one before building anything on the wrong file.
list_files shows every file that currently has the plugin open, and use_file claims one for that agent:
The claim belongs to that agent's own server process, so it never affects the other agent, it survives closing and reopening the plugin panel, and calls keep reaching the file even while its tab sits in the background. If two open files share a name (x and a second x), use_file refuses the name and asks for the sessionId that list_files prints, rather than guessing. Release it with use_file({ release: true }) to go back to following the foreground file.

What's in the name
figwright follows the -wright tradition, an old English word for a maker or craftsman: a playwright writes plays, a shipwright builds ships, a wheelwright, wheels. The name is a nod to Playwright, which automates the browser. Where Playwright drives the browser, Figwright drives Figma, a maker of designs that both reads the canvas and crafts work back onto it.
