Sneaking past Figma’s six-requests-a-month API limit

What it does

Figma MCP Bridge pairs a browser plugin with an MCP server to let AI agents read and edit Figma files without touching Figma’s REST API. Instead of burning through the free tier’s six monthly requests, the plugin opens a WebSocket backchannel that streams document trees, selections, styles, and screenshots directly to your local AI tool. It also carries an opt-in set of write tools for safe, agent-driven edits like tweaking text, fills, auto-layout, and geometry.

The interesting bit

The server maintains a registry of WebSocket connections keyed by file key, so you can open the plugin in multiple Figma files at once and let the agent target any of them. There is even leader election and follower proxying in the server architecture, which is more distributed-systems ceremony than you expect from a design-to-code bridge.

Key highlights

• Bypasses Figma’s REST API entirely, eliminating the free-tier six-requests-per-month bottleneck.
• Supports multiple simultaneous file connections; the agent routes calls by fileKey.
• Read tools cover document trees, nodes, design tokens, styles, and base64-encoded screenshots.
• Write tools allow creating frames, text, and shapes, plus patching layout, colors, strokes, and effects.
• No local binary installation required.

Caveats

• Write tools only work in Figma’s design editor; Dev Mode is read-only and returns a clear error if you try to edit.
• The write surface is intentionally limited: no components, instances, variable authoring, per-segment text styling, or vector boolean operations yet.
• Deleting nodes requires an explicit confirm: true flag, which is sensible but adds friction.

Verdict

Worth a look if you’re a free-tier Figma user trying to wire designs into Cursor or Claude without hitting the API wall. Pass if you need deep component-system automation or heavy design-token authoring — the write tools are still basic.
