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.
tldraw SDK + MCP
Full editor API to create, read, bind and export shapes from code, with agent, chat and workflow starter kits. Source-available, and commercial prices aren't published.
Before you call either
Mural MCP
- Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool
- Work on one mural at a time and name it explicitly when switching
- Request only murals:read when the task only reads a board
- Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals
- If a tool is missing or renamed, reconnect the connector to refresh the cached tool list
tldraw SDK + MCP
- Through the MCP App, call
searchon the Editor API spec first, thenexecwith JavaScript that callseditormethods - Omit
canvasIdto start a blank canvas, and pass the returnedcanvasIdto keep editing the same one - Paste Mermaid into the canvas to get editable shapes instead of placing each shape by hand
- Return
editor.getCurrentPageShapes()fromexecto check what was drawn - Read the release notes before a minor upgrade. Minor versions can break
