Which one, for what

Mumble F

Best for A person on a Mac with early access who wants a live, transcript-linked diagram of a call or workshop, kept as plain files in git, and who already pays for Claude Code or Codex.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

No API or MCP server an outside agent can call. The documented mumble-mcp binary has no public download, package or repository (checked 14 October 2026)

tldraw SDK + MCP C

Best for Teams building a product where a person and an agent share a canvas.

Verdicts

Mumble

Mumble keeps audio on the Mac and stores each conversation as plain files in ~/Mumble, with canvas JSON that diffs cleanly. 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.

tldraw SDK + MCP

Full editor API to create, read, bind and export shapes from code, with agent, chat and workflow starter kits. Source-available, and commercial prices aren't published.

Before you call either

Mumble

  1. 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
  2. Don't configure /path/to/mumble-mcp from the docs. It is a placeholder, and no binary is published
  3. If the person already has Mumble, read ~/Mumble/<capture>/ directly, capture.json for the transcript and diagram.canvas for the map
  4. 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
  5. Don't write to a capture that is being recorded. The app doesn't merge the two versions

tldraw SDK + MCP

  1. Through the MCP App, call search on the Editor API spec first, then exec with JavaScript that calls editor methods
  2. Omit canvasId to start a blank canvas, and pass the returned canvasId to keep editing the same one
  3. Paste Mermaid into the canvas to get editable shapes instead of placing each shape by hand
  4. Return editor.getCurrentPageShapes() from exec to check what was drawn
  5. Read the release notes before a minor upgrade. Minor versions can break

Disclosure

Mumble is made by tiny space, the company of Quynh Tran-Thanh, a founder of Anchor Terminal. 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.
