cursor-talk-to-figma-mcp
Provides an MCP server (plus a companion WebSocket + Figma plugin) that lets an AI agent read Figma/FigJam documents and programmatically modify design elements (e.g., text, layout, styling, components/overrides, connections, annotations) via MCP tools.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No authentication/authorization is described in the provided README for MCP/WebSocket usage. WebSocket hostname change for Windows/WSL suggests network exposure can be configured; without auth this increases risk if reachable beyond localhost. TLS enforcement and secret handling practices are not documented. Dependencies listed are general libraries; no vulnerability posture is described in the provided materials.
⚡ Reliability
Best When
You have an interactive agent workflow (Cursor/Claude Code) connected to a developer-run local WebSocket + MCP server and you want structured, tool-based access to Figma for iterative design automation.
Avoid When
You need network-accessible, internet-facing endpoints or strong access control without adding your own authentication/authorization layer around the WebSocket/MCP server.
Use Cases
- • Read document/selection info from Figma for agent-driven edits
- • Batch replace or re-chunk text nodes and update multiple nodes efficiently
- • Apply auto-layout properties (layout mode, padding, spacing, sizing, alignment)
- • Modify styling (fill/stroke/corner radius) and reposition/resize/clone/delete nodes
- • Work with component instances by extracting and setting instance overrides
- • Convert prototype reactions into FigJam connector lines and flows
- • Create/update native annotations and batch annotation operations
- • Scan nodes by types to find targets for downstream edits
Not For
- • Security-critical automation without additional hardening (no explicit auth shown in docs)
- • Operations requiring fine-grained permissions/auditing per user/project out of the box
- • Production deployments needing documented operational guarantees (SLA, uptime, incident handling)
- • High-reliability bulk edits without validating idempotency and failure modes
Interface
Authentication
README describes joining a channel and running a local WebSocket server but does not document authentication, authorization, or per-user permissions for the MCP/WebSocket endpoints.
Pricing
Pricing not mentioned; npm package and developer-run Figma interactions imply costs are primarily your infrastructure/agent usage.
Agent Metadata
Known Gotchas
- ⚠ Must join a channel before sending commands (ordering dependency)
- ⚠ Bulk/scan operations on large designs may require chunking parameters (agent must pass/choose them)
- ⚠ Some operations are not fully supported (e.g., export returning base64 as text is noted as limited)
- ⚠ Failure modes for destructive operations (delete) and repeated runs are not described; agent should verify node existence/state before/after edits
