Think of `routing` and `postLayout` as **alternatives**: use `routing: \"libavoid\"` to keep your positions and only fix the wires, or `postLayout: \"elk\"` to re-lay-out the vertices — and note ELK already routes its edges decently, so when you use `postLayout` you normally should **not** also set `routing` (the combination is redundant in almost all cases).

There is no API or MCP server an outside agent can call today. The documented `mumble-mcp` has no public download, package or repository, and the app is reached only through an early-access waitlist.\n\n## Before you call either\n\n### draw.io + MCP\n\n1. Pass `mermaid` to `create_diagram` for any type on its Mermaid list. Use `xml` only for icons, mockups or hand-placed layouts\n2. Call `search_shapes` before writing XML with cloud or network icons, so the style strings are exact\n3. Set `postLayout: \"elk\"` for flowcharts or `routing: \"libavoid\"` for hand-placed diagrams, never both\n4. Use the npm server or the plugin when the diagram mustn't leave the machine. The hosted App sends it to draw.io's server\n5. Expect the tool list to cost about 13,000 tokens before the first call\n\n### Mumble\n\n1. Don't plan to call Mumble from another agent. Neither the app nor `mumble-mcp` can be obtained publicly, so hand the task to a person with early access\n2. Don't configure `/path/to/mumble-mcp` from the docs. It is a placeholder, and no binary is published\n3. If the person already has Mumble, read ~/Mumble/\u003ccapture\u003e/ directly, `capture.json` for the transcript and `diagram.canvas` for the map\n4. Keep canvas keys in schema order and never rename a node id, or the edges that name it are orphaned and the canvas is refused. Use git as the undo\n5. Don't write to a capture that is being recorded. The app doesn't merge the two versions\n\n## Questions\n\n### Which is better for AI agents, draw.io + MCP or Mumble?\n\ndraw.io + MCP scores 62.2 (B) on agent readiness against Mumble's 7.5 (F), and leads in every scored category.\n\n### Can an agent call draw.io + MCP and Mumble without installing anything?\n\ndraw.io + MCP has a hosted endpoint at https://mcp.draw.io/mcp.

It's graded the same way as every listing, by the same published checklist with the same readings, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed. letme never picks it.\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "attributionRequired": true, "credit": "CC BY 4.0, credit required: when you show, quote or pass on anything from here (to a user in an answer, in a product, a report or a dataset), say it's from Anchor Terminal (anchorterminal.com) and link the page or API address you took it from.
