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.\n\n**Miro API + MCP.** REST creates shapes, connectors and frames, so flowcharts and architecture sketches can be drawn directly. Legacy MCP board tools were removed nine days after the deprecation notice.\n\n## Before you call either\n\n### Melius\n\n1. 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\n2. Over MCP, call `get_guide` first, `show_presence` before node changes and `canvas_plan_layout` before `bulk_create_nodes`\n3. 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\n4. Read credit costs from GET /generation/models?category=image before a bulk run. A 400 can mean the team is out of credits\n5. Downloads arrive as a ZIP from a signed URL. Fetch that URL without the `Authorization` header\n\n### Miro API + MCP\n\n1. Create shapes first, then connectors with `startItem` and `endItem` ids\n2. Put related items in a frame and set `parent` so they move together\n3. Watch `X-RateLimit-Remaining`. There's no `Retry-After`, so back off exponentially on 429\n4. Through MCP, call `canvas_read_as_svg` before `canvas_update_from_svg` so the model sees the current layout\n5. Don't call the legacy MCP board tools. They were removed on 17 September 2026\n\n## Questions\n\n### Which is better for AI agents, Melius or Miro API + MCP?\n\nMiro API + MCP scores 65 (B) on agent readiness against Melius's 54.1 (C), and leads in every scored category.\n\n### Do Melius and Miro API + MCP need an API key?\n\nMelius takes an API key or an OAuth sign-in. Miro API + MCP uses an OAuth sign-in.\n\n### Can an agent call Melius and Miro API + MCP without installing anything?\n\nYes.
