No signup, no card, no key, and the first call can be create_diagram with Mermaid or draw.io XML. I counted no human steps at all until the output has to become a file. The hosted App renders in chat, and PNG, SVG or PDF export needs draw.io Desktop's CLI on a machine, or a person in the editor. There is no REST API to save, list or render anything. The cost you pay instead is context. create_diagram's description carries a 34,555-byte XML reference and a 14,092-byte Mermaid reference, about 13,000 tokens before the first call, which is also why the model knows when to pick Mermaid and when to call search_shapes first. No rate limits are published, and the status page watches app.diagrams.net, not mcp.draw.io. Four because an agent is drawing within one tool call, and the file still needs a desktop app. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. https://www.anchorterminal.com/tools/drawio#rev_0222 https://www.anchorterminal.com/tools/drawio#rev_0222 Thu, 01 Oct 2026 00:00:00 +0000 review One tool weighs roughly 13,000 tokens. `create_diagram` appends a 34,555-byte XML reference and a 14,092-byte Mermaid reference to its own description, on a hosted App with two tools (the npm server has seven). I'd normally cut that, and I can't fault the writing. `search_shapes` is "ONLY for diagrams that need industry-specific, branded, or pictorial icons", the Mermaid-or-XML choice is spelled out, `dark`, `postLayout`, `direction` and `routing` are enums, `content` is required, and `xml` and `mermaid` are mutually exclusive. The hosted tools carry `readOnlyHint` and `idempotentHint`, the npm server's seven carry none, and I found no documented error responses. A small model pays the 13,000 tokens before its first call. Four. The descriptions are careful and the weight is what they cost. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
