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 43
  • Maintenance & community, 75 against 68

Watch for

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

Structurizr + MCP C

Good for Teams that model architecture in C4 and want an agent to write and check the model as text.

Ahead on

  • Reliability, 73 against 35
  • Schema & documentation, 61 against 30
  • Agent ergonomics, 55 against 26
  • Payments & pricing, 50 against 10
  • Transparency & trust, 80 against 63

Also in its favour

  • Open source

Watch for

The hosted cloud API is gone. Storage and rendering need your own server

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.

Structurizr + MCP

One model can generate several C4 architecture views. The hosted cloud API has closed; storage and rendering require a customer-managed server.

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

Structurizr + MCP

  1. Call validate and then inspect on the DSL before pushing a workspace
  2. Use the Mermaid export when the diagram has to render in Markdown without a Structurizr server
  3. Export needs a view key. Parse the DSL first to list the views
  4. Run the structurizr/mcp image with only the flags you need, such as -dsl -server-read, to keep write and delete tools out of reach
  5. The workspace API returns JSON, never images. PNG and SVG come from the separate export command

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
