figma design data extraction with css translation
Fetches raw Figma file and node data via the Figma REST API, then applies a multi-stage extraction and transformation pipeline that filters metadata, converts Figma auto-layout concepts to CSS flexbox properties, translates effect objects to box-shadow CSS, and generates CSS-compatible color values. The extraction system (src/extractors) isolates layout and styling information while the transformer layer (src/transformers) performs semantic translation from Figma's design model to web-implementable CSS, outputting simplified JSON or YAML optimized for LLM consumption.
Unique: Implements a two-stage extraction-transformation pipeline (src/extractors + src/transformers) that not only filters Figma's verbose API responses but semantically translates Figma design concepts (auto-layout, effects, colors) into CSS equivalents, rather than passing raw design data to the LLM. This reduces token overhead and improves code generation accuracy by pre-normalizing design semantics.
vs alternatives: Unlike screenshot-based design handoff or raw Figma API responses, this capability delivers structured, CSS-normalized design data that LLMs can directly implement without interpretation overhead, improving one-shot accuracy significantly.
mcp protocol-based tool exposure for ai agents
Implements the Model Context Protocol (MCP) server specification using @modelcontextprotocol/sdk v1.10.2, exposing Figma capabilities as standardized MCP tools (get_figma_data, download_figma_images) that AI agents like Cursor can discover and invoke via a schema-based function registry. The MCP layer (src/mcp.ts) handles protocol serialization, request routing, and response formatting, allowing any MCP-compatible client to call Figma operations without custom integration code.
Unique: Implements full MCP server specification with multiple transport layers (StdioServerTransport, SSEServerTransport, StreamableHTTPServerTransport in src/server.ts), allowing the same Figma capability to be exposed via stdio (for local agents), HTTP (for remote agents), or SSE (for browser-based clients). This multi-transport approach is more flexible than single-protocol implementations.
vs alternatives: Provides standardized MCP protocol integration vs. custom REST APIs or plugin systems, enabling Figma access across any MCP-compatible AI tool without per-tool integration work.
batch asset retrieval and optimization
Provides batch operations for downloading multiple assets from a Figma file in a single request, with optional image optimization (compression, format conversion). The batch retrieval system (src/index.ts image processing) collects asset node IDs, fetches them in parallel from Figma's CDN, and optionally applies optimization (e.g., SVG minification, PNG compression) before delivery. This reduces latency and network overhead compared to fetching assets individually.
Unique: Implements batch asset retrieval with optional optimization in a single operation, reducing latency and network overhead compared to individual asset fetches. The batch system understands Figma asset types and applies appropriate optimization (SVG minification vs. PNG compression) automatically.
vs alternatives: Provides efficient batch asset retrieval with automatic optimization vs. individual asset downloads or manual export, reducing latency and improving workflow efficiency for asset-heavy designs.
real-time figma file monitoring and change detection
Implements optional polling-based change detection that periodically fetches Figma file metadata and compares against cached state to identify design updates. The monitoring system (if implemented in src/services/figma.ts) tracks file modification timestamps and node-level changes, allowing the MCP server to notify clients when designs have been updated. This enables AI agents to work with fresh design data without manual refresh.
Unique: Implements optional polling-based change detection that tracks Figma file modifications and notifies clients of updates, enabling reactive design-to-code workflows. This is distinct from passive design fetching because it proactively monitors for changes and triggers updates.
vs alternatives: Provides automatic change detection vs. manual refresh or static design snapshots, enabling continuous design-to-code workflows where AI agents automatically regenerate code when designs update.
figma asset download with format conversion
Implements the download_figma_images MCP tool that retrieves SVG and PNG assets directly from Figma designs, handling format conversion and optimization. The image processing pipeline (src/index.ts image processing section) manages asset fetching from Figma's CDN, format selection based on design node type, and optional image optimization before delivery to the AI agent. Supports both vector (SVG) and raster (PNG) formats with automatic selection based on node properties.
Unique: Integrates Figma's native asset export API with format-aware selection logic, automatically choosing SVG for vector nodes and PNG for raster content, then delivering assets in formats optimized for AI consumption (data URIs, base64) rather than raw file downloads. This eliminates the need for separate image processing steps in the AI agent.
vs alternatives: Provides direct asset retrieval from Figma's API vs. manual export or screenshot-based asset extraction, with automatic format selection and optimization for code generation workflows.
multi-transport mcp server deployment
Provides three transport layer implementations (src/server.ts) for deploying the MCP server: StdioServerTransport for local CLI integration, SSEServerTransport for HTTP long-polling, and StreamableHTTPServerTransport for REST-based MCP communication. The transport abstraction allows the same MCP server logic to run in different deployment contexts (local CLI, HTTP server on port 3333, or embedded in Node.js applications) without code changes. Server orchestration (src/server.ts) selects transport based on environment or CLI arguments.
Unique: Implements transport abstraction layer that decouples MCP protocol logic from transport mechanism, allowing the same server to operate via stdio (for Cursor), HTTP (for remote agents), or SSE (for browser clients) by swapping transport implementations. This is more flexible than single-transport MCP servers that lock users into one deployment model.
vs alternatives: Supports multiple deployment patterns (local CLI, HTTP server, embedded) from a single codebase vs. separate implementations for each transport, reducing maintenance burden and enabling teams to scale from local development to shared infrastructure.
configuration management with environment and cli argument support
Implements a configuration system (src/config.ts) that reads Figma API credentials and server settings from multiple sources with a priority hierarchy: CLI arguments override environment variables, which override defaults. Supports both Personal Access Token and OAuth Bearer Token authentication methods, allowing flexible credential management across local development, CI/CD, and production deployments. Configuration is validated at startup to fail fast if required credentials are missing.
Unique: Implements a priority-based configuration resolver that merges CLI arguments, environment variables, and defaults in a single pass, with explicit support for both Personal Access Token and OAuth Bearer Token methods. This allows the same server code to work across local development (env vars), CI/CD (secrets), and production (OAuth) without configuration changes.
vs alternatives: Provides flexible multi-source configuration with explicit token type support vs. single-method credential systems, enabling teams to use different authentication strategies across environments without code changes.
figma api client with request handling and error recovery
Implements a Figma API client (src/services/figma.ts) that wraps the Figma REST API with authentication, request construction, and error handling. The client manages API calls to fetch file data, node information, and asset URLs, handling Figma's pagination for large files and implementing exponential backoff for rate-limit recovery. Abstracts Figma API specifics (authentication headers, endpoint construction, response parsing) from the extraction and transformation layers, providing a clean interface for design data retrieval.
Unique: Wraps Figma's REST API with a dedicated service layer (src/services/figma.ts) that handles authentication, pagination, and exponential backoff for rate limiting, isolating API complexity from extraction logic. This allows extraction and transformation layers to focus on design semantics rather than HTTP concerns.
vs alternatives: Provides a managed Figma API client with built-in error recovery vs. raw HTTP calls or third-party SDKs, reducing boilerplate and improving reliability in production deployments.
