Loom MCP

Figma to React code converter via compact DSL. Available as an MCP server and CLI.

Converts Figma design JSON into React components using a hybrid approach (programmatic + LLM). A custom DSL intermediate representation achieves 96.6% token reduction compared to raw Figma JSON.

MCP Server

Setup (Claude Code)

claude mcp add loom --scope user -- npx @keisuke-na/loom-mcp

Or manually add to your MCP config (.mcp.json for per-project, ~/.claude/settings.json for global):

{
  "mcpServers": {
    "loom": {
      "command": "npx",
      "args": ["@keisuke-na/loom-mcp"]
    }
  }
}

Requires FIGMA_PERSONAL_ACCESS_TOKEN environment variable.

Tools

Tool	Description
generate-dsl	Convert a Figma component URL to compact DSL
generate-react	Convert annotated semantic DSL to React components
list-components	List cached component names
get-component	Retrieve a specific component's code

Workflow

1. generate-dsl with a Figma URL — returns DSL body
2. LLM annotates the DSL with .as(), .tag(), .repeat()
3. generate-react with annotated DSL — generates and caches React components
4. get-component to retrieve individual components as needed

CLI

# React code generation
npx @keisuke-na/loom-mcp <input.json> [--file-key=FILE_KEY]

# DSL generation
npx @keisuke-na/loom-mcp <input.json> --format=dsl

# DSL body only (for LLM input)
npx @keisuke-na/loom-mcp <input.json> --format=dsl --body-only

# Semantic DSL to React
npx @keisuke-na/loom-mcp <semantic.dsl> --format=semantic-react --vars=<vars.dsl>

How It Works

Figma REST API (JSON)
    |
[Stage 1]   JSON -> pixel-perfect React code
[Stage 1.5] JSON -> compact DSL (96.6% token reduction)
[Stage 2]   LLM annotates DSL with .as, .tag, .repeat
[Stage 2.5] Semantic DSL + variables -> componentized React code
