## Which one, for what

### Mural MCP (E)

Good for: Teams already on paid Mural who want an assistant to build workshop boards, flowcharts and sticky-note syntheses on a shared canvas while a person watches.

Ahead on:
- Security & auth, 72 against 58
- Maintenance & community, 75 against 56

Watch for: Public preview, with Mural's service levels and support obligations excluded

### Whimsical MCP (D)

Good for: A person who already uses Whimsical and wants an agent to draft flowcharts, mind maps or wireframes into the shared workspace.

Ahead on:
- Reliability, 60 against 35
- Schema & documentation, 54 against 30
- Agent ergonomics, 46 against 26
- Payments & pricing, 25 against 10
- Transparency & trust, 72 against 63

Watch for: No API keys, so it can't run headless or in CI

## 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
