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.\n\n**Structurizr + MCP.** One model can generate several C4 architecture views. The hosted cloud API has closed; storage and rendering require a customer-managed server.\n\n## Before you call either\n\n### Mural MCP\n\n1. Ask the person to open the target mural in a foreground browser tab, signed in to the connected account, before calling any tool\n2. Work on one mural at a time and name it explicitly when switching\n3. Request only murals:read when the task only reads a board\n4. Deletes go through without a server-side prompt. Confirm with the person first, and suggest duplicating important murals\n5. If a tool is missing or renamed, reconnect the connector to refresh the cached tool list\n\n### Structurizr + MCP\n\n1. Call `validate` and then `inspect` on the DSL before pushing a workspace\n2. Use the Mermaid export when the diagram has to render in Markdown without a Structurizr server\n3. Export needs a view key. Parse the DSL first to list the views\n4. 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\n5. The workspace API returns JSON, never images. PNG and SVG come from the separate export command\n\n## Questions\n\n### Which is better for AI agents, Mural MCP or Structurizr + MCP?\n\nStructurizr + MCP scores 60.2 (C) on agent readiness against Mural MCP's 42 (E), and leads in 5 of 7 scored categories. Mural MCP leads on security \u0026 auth and maintenance \u0026 community.\n\n### Do Mural MCP and Structurizr + MCP need an API key?\n\nMural MCP uses an OAuth sign-in. Structurizr + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Mural MCP and Structurizr + MCP without installing anything?\n\nYes. Mural MCP has a hosted endpoint at https://mcp-canvas.mural.co/mcp and Structurizr + MCP at https://mcp.structurizr.com/mcp.\n\n### Are Mural MCP and Structurizr + MCP open source?\n\nNo open-source release is listed for Mural MCP. Structurizr + MCP is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/mural-mcp-vs-structurizr.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mural-mcp-vs-structurizr.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mural-mcp\", \"b\": \"structurizr\"}`.
