Verdicts

draw.io + MCP

Free, keyless and Apache 2.0, with a Docker image for self-hosting. Tool descriptions embed a 34.5 KB XML reference and a 14 KB Mermaid reference, roughly 13,000 tokens.

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.

Before you call either

draw.io + MCP

  1. Pass mermaid to create_diagram for any type on its Mermaid list. Use xml only for icons, mockups or hand-placed layouts
  2. Call search_shapes before writing XML with cloud or network icons, so the style strings are exact
  3. Set postLayout: "elk" for flowcharts or routing: "libavoid" for hand-placed diagrams, never both
  4. 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
  5. Expect the tool list to cost about 13,000 tokens before the first call

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
