## 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

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

### tldraw SDK + MCP

1. Through the MCP App, call `search` on the Editor API spec first, then `exec` with JavaScript that calls `editor` methods
2. Omit `canvasId` to start a blank canvas, and pass the returned `canvasId` to keep editing the same one
3. Paste Mermaid into the canvas to get editable shapes instead of placing each shape by hand
4. Return `editor.getCurrentPageShapes()` from `exec` to check what was drawn
5. Read the release notes before a minor upgrade. Minor versions can break
