Verdicts

Figma API + MCP

OpenAPI spec, TypeScript types and an llms.txt index for the REST API. View and Collab seats get 6 MCP calls a month on paid plans.

Melius

One backend serves a 59-operation REST API with a public OpenAPI spec, a hosted MCP server with OAuth sign-in and a JSON-only CLI, and the status page shows no incidents since July 2026. API keys carry no scopes and work with their creator's role, and no rate-limit numbers, changelog or per-model credit prices are published.

Before you call either

Figma API + MCP

  1. Pass ids= and depth= to GET /v1/files/:key. A whole file is large
  2. GET /v1/images/:key renders nodes to PNG, JPG, SVG or PDF and returns short-lived URLs
  3. On 429 read Retry-After. Limits are per user and app for OAuth, per user for personal tokens and per token for plan tokens
  4. Use the v2 folders endpoints. The v1 projects endpoints were deprecated on 10 August 2026
  5. Confirm the credit cost with the user when weave_run_tool returns cost_confirmation_required

Melius

  1. Generate by creating a node on a canvas, starting a run with POST /nodes/{nodeId}/runs, then polling GET /node-runs/{nodeRunId} until status is finished or failed
  2. Over MCP, call get_guide first, show_presence before node changes and canvas_plan_layout before bulk_create_nodes
  3. On 429 wait Retry-After seconds. After a timeout or 5xx on a write, read the canvas or run state before resubmitting, because there are no idempotency keys
  4. Read credit costs from GET /generation/models?category=image before a bulk run. A 400 can mean the team is out of credits
  5. Downloads arrive as a ZIP from a signed URL. Fetch that URL without the Authorization header

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
