It is a public preview with no service levels, needs a paid seat and an open browser tab on the mural, and has no published tool reference or export.\n\n**Whimsical MCP.** OAuth 2.1 with PKCE and separate read and write scopes. No API keys, so it can't run headless or in CI.\n\n## Before you call either\n\n### Mural MCP\n\n1. Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool\n2. Work on one mural at a time and name it explicitly when switching\n3. Request only murals:read when the task only reads a board\n4. Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals\n5. If a tool is missing or renamed, reconnect the connector to refresh the cached tool list\n\n### Whimsical MCP\n\n1. Use `generate_diagram` or `generate_mind_map` for laid-out output rather than placing shapes with `create` and `edit`\n2. Call `how_to` for Whimsical's syntax before writing a large diagram\n3. Use `fetch` when you need a PNG snapshot of a board\n4. `delete` removes files or objects without asking. Confirm with the person first\n\n## Questions\n\n### Which is better for AI agents, Mural MCP or Whimsical MCP?\n\nWhimsical MCP scores 52.7 (D) on agent readiness against Mural MCP's 42 (E), and leads in 5 of 7 scored categories. Mural MCP leads on security \u0026 auth and maintenance \u0026 community.\n\n### Do Mural MCP and Whimsical MCP need an API key?\n\nBoth use an OAuth sign-in.\n\n### Can an agent call Mural MCP and Whimsical MCP without installing anything?\n\nYes.
