Verdicts

Mural MCP

Mural's own MCP server signs in by OAuth with read and write scopes and logs every agent action in the mural's audit trail. 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.

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.

Before you call either

Mural MCP

  1. Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool
  2. Work on one mural at a time and name it explicitly when switching
  3. Request only murals:read when the task only reads a board
  4. Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals
  5. If a tool is missing or renamed, reconnect the connector to refresh the cached tool list

Whimsical MCP

  1. Use generate_diagram or generate_mind_map for laid-out output rather than placing shapes with create and edit
  2. Call how_to for Whimsical's syntax before writing a large diagram
  3. Use fetch when you need a PNG snapshot of a board
  4. delete removes files or objects without asking. Confirm with the person first
