cursor-talk-to-figma-mcp AGENTS.md

Project instructions for an MCP server that connects coding assistants such as Cursor and Claude Code to Figma, a collaborative design tool.

In plain words
What is it for?
They help developers work on the server, start its WebSocket relay, configure assistant connections, and understand its tools for changing designs and exporting images.
Why use it?
They explain how to install, build, run, and configure the server, as well as how its assistant, relay, and Figma-plugin parts communicate.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cursor-talk-to-figma-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code agents (claude.ai/code) when working with code in this repository.

Project Overview

MCP (Model Context Protocol) server that bridges AI agents (Cursor, Claude Code) with Figma. Three components communicate in a pipeline:

Claude Code / Cursor ←(stdio)→ MCP Server ←(WebSocket)→ WebSocket Relay ←(WebSocket)→ Figma Plugin

Build & Development Commands

bun install              # Install dependencies
bun run build            # Build MCP server (tsup → dist/)
bun run dev              # Build in watch mode
bun socket               # Start WebSocket relay server (port 3055)
bun run start            # Run built MCP server
bun setup                # Full setup (install + write .cursor/mcp.json + .mcp.json)

There is no test suite or linter configured.

Architecture

MCP Server (src/talk_to_figma_mcp/server.ts)

The main server implementing the MCP protocol via @modelcontextprotocol/sdk. Exposes 50+ tools (create shapes, modify text, manage layouts, export images, etc.) and several AI prompts (design strategies). Communicates with the AI agent over stdio and with the WebSocket relay via ws. Each request gets a UUID, is tracked in a pendingRequests Map with timeout/promise callbacks, and resolves when the plugin responds.

WebSocket Relay (src/socket.ts)

Lightweight Bun WebSocket server on port 3055 (configurable via PORT env). Routes messages between MCP server and Figma plugin using channel-based isolation. Clients call join to enter a channel; messages broadcast only within the same channel.

Figma Plugin (src/cursor_mcp_plugin/)

Runs inside Figma. code.js is the plugin main thread handling 30+ commands via a dispatcher. ui.html is the plugin UI for WebSocket connection management. manifest.json declares permissions (dynamic-page access, localhost network). The plugin is not built/bundledcode.js is written directly as the runtime artifact.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
