Figma

MCP

Figma Dev Mode server — read components, variables, and layout; generate code from frames; create and update canvas content. Enable the desktop MCP server (Dev Mode) on port 3845.

Builds accessible, performant, maintainable UI components and frontend features.

Build, scaffold, refactor, and troubleshoot ChatGPT Apps SDK applications that combine an MCP server and widget UI. Use when Codex needs to design tools, register UI resources, wire the MCP Apps bridge or ChatGPT compatibility APIs, apply Apps SDK metadata or CSP or domain settings, or produce a docs-aligned project scaffold. Prefer a docs-first workflow by invoking the openai-docs skill or OpenAI developer docs MCP tools before generating code.

Design one-off HTML artifacts (landing, deck, prototype).

Debug Hermes TUI slash commands: Python, gateway, Ink UI.

Author/validate/export Google's DESIGN.md token spec files.

Translates Figma designs into production-ready application code with 1:1 visual fidelity. Use when implementing UI code from Figma files, when user mentions "implement design", "generate code", "implement component", provides Figma URLs, or asks to build components matching Figma specs. For Figma canvas writes via `use_figma`, use `figma-use`.

Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.

Builds production-quality UIs. Use when building or modifying user-facing interfaces. Use when creating components, implementing layouts, managing state, or when the output needs to look and feel production-quality rather than AI-generated.

Debug Node.js via --inspect + Chrome DevTools Protocol CLI.

Use when you need to generate UI designs, web/mobile mockups, presentations, dashboards, or documents from natural language. 31 composable skills across 129 design systems with image, video, and audio generation.

Use when the task requires automating a real browser from the terminal (navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging) via `playwright-cli` or the bundled wrapper script.

Persistent browser and Electron interaction through `js_repl` for fast iterative UI debugging.

Build a throwaway prototype to flesh out a design — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route.

Throwaway HTML mockups: 2-3 design variants to compare.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
