Figma Model Context Protocol Orchestrator

An integrated framework engineered for programmatic manipulation and creation of interfaces within Figma, driven entirely by natural language directives processed through the Cursor Agent leveraging the Model Context Protocol specification.

System Synopsis

This architecture empowers AI-driven visual construction inside Figma based on vernacular instructions submitted via the Cursor Agent interface. The solution is bifurcated into two principal modules:

1. MCP Communication Hub: A TypeScript-based service running on the Bun runtime, responsible for adhering to the MCP specification and relaying commands to the Figma extension over persistent WebSocket connections.
2. Figma Execution Agent: A specialized plugin residing within the Figma environment, tasked with interpreting and rendering the design modifications dictated by the server.

This interconnected system grants users the ability to generate or revise visuals using plain text instructions, enabling: - Instantiation of rudimentary graphical primitives (e.g., shapes, text blocks). - Development of comprehensive page structures incorporating multiple distinct sections. - Targeted modification of pre-existing design artifacts.

Project Directory Layout

• mcp-backend-service/: Contains the core MCP server logic.
• figma-interaction-plugin/: Houses the necessary code for the Figma environment client.

Initial Setup Protocol

Phase 1: Backend Service Deployment

bash cd mcp-backend-service cp environment_defaults.env .env # Configure necessary credentials, including Figma authorization key bun install bun start:dev

Phase 2: Frontend Plugin Installation

bash cd figma-interaction-plugin npm install npm run package

Subsequent import into Figma: 1. Launch Figma application. 2. Navigate to Plugins -> Development -> Import plugin from manifest. 3. Point to the figma-interaction-plugin/manifest.json file.

Phase 3: Agent Connectivity Configuration

Within the Cursor application settings: 1. Access Settings > Agent > Managed MCP Endpoints. 2. Register a new server endpoint pointing to: http://localhost:3000/api/mcp/schema

Illustrative Command Example

Once the pipeline is fully operational, Cursor Agent can process sophisticated requests such as:

Construct a primary marketing landing page layout featuring a top navigation bar, a central promotional block displaying the headline "Revolutionary Tools" and descriptive text "Driving efficiency across all operational domains", three distinct feature showcases, and a closing informational footer.

Operational Flow Diagram

1. Cursor Agent interprets the user's natural language input.
2. A formally structured request adhering to the MCP schema is dispatched to the designated MCP server.
3. The backend service parses the directive and relays execution commands to the Figma extension via the established WebSocket link.
4. The Figma extension accurately executes the requested geometry and style transformations within the active canvas.
