What is figma-plugin-api?

Instructions and code patterns for using the Figma Plugin API through figma_exec, which runs code inside the Figma plugin environment.

Use them to find frames, inspect selected objects, read node properties, and export a selected node as a PNG.

They explain the API's access limits and show safe ways to inspect Figma nodes and export images.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add shinjiyu/figma_mcp --skill figma-plugin-api

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.00395
Opus 5	$0.00017	$0.00198
Sonnet 5	$0.00007	$0.00079
Haiku 4.5	$0.00003	$0.00040

Security

Grade A, and why

figma-plugin-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

figma_exec (Plugin API)

Code runs in the plugin main thread with global figma.

Do

return plain objects / arrays / numbers / strings
await figma.getNodeByIdAsync(id) under documentAccess: dynamic-page
Map nodes yourself:

return figma.currentPage.selection.map((n) => ({
  id: n.id,
  name: n.name,
  type: n.type,
  x: n.x,
  y: n.y,
  width: n.width,
  height: n.height,
}));

Don't

Rely on REST / Personal Access Tokens (not used by this MCP)
Return giant binary / image bytes unless asked
Expect the plugin panel to stay connected if the user closed it

Useful snippets

Find frames by name

const hits = figma.currentPage.findAll(
  (n) => n.type === "FRAME" && n.name.includes("主界面")
);
return hits.map((n) => ({
  id: n.id,
  name: n.name,
  w: n.width,
  h: n.height,
}));

Export PNG (base64) for one node

const node = figma.currentPage.selection[0];
if (!node) return { ok: false, error: "no selection" };
const bytes = await node.exportAsync({ format: "PNG", constraint: { type: "SCALE", value: 1 } });
// Return length only by default — full base64 can be huge.
return { id: node.id, name: node.name, byteLength: bytes.byteLength };

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

figma-plugin-api is a skill published in the GitHub repository shinjiyu/figma_mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 395 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
