Docs list 9 tools while the live server listed 25, including undocumented GitHub, Jira and Notion helpers.\n\n## Before you call either\n\n### Cloudviz API\n\n1. Call `GET /aws/accounts/` first to get the Cloudviz account ID, then request `/aws/accounts/{account-id}/{region}/{format}`\n2. On a 202, wait and repeat the same GET until the diagram is ready\n3. Ask for `jsonSnapshot` or `jsonDiagram` (there is no plain `json` format) when the agent has to reason over resources\n4. Use a read-only key unless the agent has to add, change or delete AWS accounts\n\n### Mermaid Chart MCP\n\n1. Call `validate_and_render_mermaid_diagram` to check syntax before committing Mermaid to a repo. It needs no token\n2. Only add the token if you need to save into Mermaid Chart projects. It reaches every project on the account\n3. If you only need a picture, the open-source mermaid-cli renders locally with no network call\n4. Use mcp.mermaid.ai. The registry still lists the older mcp.mermaidchart.com host\n\n## Other comparisons with Cloudviz API or Mermaid Chart MCP\n\n- [Cloudviz API vs Diagrams.so API + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-diagrams-so.md)\n- [Cloudviz API vs draw.io + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-drawio.md)\n- [Cloudviz API vs Eraser API + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-eraser.md)\n- [Cloudviz API vs Lucid API + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-lucid.md)\n- [Cloudviz API vs Structurizr + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-structurizr.md)\n- [Cloudviz API vs tldraw SDK + MCP](https://www.anchorterminal.com/compare/cloudviz-vs-tldraw.md)\n- [Cloudviz API vs Whimsical MCP](https://www.anchorterminal.com/compare/cloudviz-vs-whimsical.md)\n- [Diagrams.so API + MCP vs Mermaid Chart MCP](https://www.anchorterminal.com/compare/diagrams-so-vs-mermaid-chart.md)\n- [draw.io + MCP vs Mermaid Chart MCP](https://www.anchorterminal.com/compare/drawio-vs-mermaid-chart.md)\n- [Eraser API + MCP vs Mermaid Chart MCP](https://www.anchorterminal.com/compare/eraser-vs-mermaid-chart.md)\n- [Lucid API + MCP vs Mermaid Chart MCP](https://www.anchorterminal.com/compare/lucid-vs-mermaid-chart.md)\n- [Mermaid Chart MCP vs Structurizr + MCP](https://www.anchorterminal.com/compare/mermaid-chart-vs-structurizr.md)\n- [Mermaid Chart MCP vs tldraw SDK + MCP](https://www.anchorterminal.com/compare/mermaid-chart-vs-tldraw.md)\n- [Mermaid Chart MCP vs Whimsical MCP](https://www.anchorterminal.com/compare/mermaid-chart-vs-whimsical.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-04", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Cloudviz API vs Mermaid Chart MCP", "url": "" } ], "description": "Cloudviz API has a score of 37.9 (F) against Mermaid Chart MCP's 31.7 (F).
