Legacy MCP board tools were removed nine days after the deprecation notice.\n\n**Subframe.** An agent can read and change pages, components, snippets and themes in a Subframe project through a hosted MCP server with OAuth, and Viewer accounts get a read-only server. The server lists 46 tools, and no status page, rate limits, changelog or security contact were found. Three tools were renamed in September 2026 with no notice found.\n\n## Before you call either\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### Subframe\n\n1. Connect with an MCP client that supports OAuth. The server rejects Subframe access tokens and static `Authorization` headers\n2. Pass `projectId` on every call. When it is omitted the server uses the first project the user can reach, which may be the wrong team's\n3. After `design_page`, `design_component` or `edit_component`, call `wait_for_jobs` with the `jobId` before reading the result. Earlier reads return stale content\n4. Ask the owner before any delete tool or a theme token deletion. A deleted token leaves every reference detached even after the token is restored\n5. For the CLI, set `SUBFRAME_AUTH_TOKEN` and `DO_NOT_TRACK=1`, and point `--dir` at a folder that holds only Subframe code, because a full sync removes other unprotected files\n\n## Questions\n\n### Which is better for AI agents, Miro API + MCP or Subframe?\n\nMiro API + MCP scores 65 (B) on agent readiness against Subframe's 39.7 (E), and leads in 6 of 7 scored categories.\n\n### Do Miro API + MCP and Subframe need an API key?\n\nMiro API + MCP uses an OAuth sign-in. Subframe takes an API key or an OAuth sign-in.\n\n### Can an agent call Miro API + MCP and Subframe without installing anything?\n\nYes.
