In development that's the flow. The hosted MCP App is one URL with no signup, and its two model-facing tools are search over the Editor API spec and exec, which runs model-written JavaScript on the canvas with no approval step. Then the browser requirement shows up on every path. The canvas runs in a React host, the MCP App needs a host that renders MCP Apps, and there is no server-side REST API, so a headless agent can't produce a file without a browser somewhere. Production needs a licence key. A 100-day trial comes by form with no payment, a hobby key shows a watermark at tldraw's discretion, and commercial prices are set by sales. Trial and hobby builds ping tldraw with the full page URL. Two because it's a canvas for a person and an agent sharing a screen, and an agent on its own has nowhere to run it.

Six tools exist, the model sees two, and four checkpoint tools are app-only and hidden. `search` queries an extracted Editor API spec and returns the matching parts, not the whole thing. The `exec` description tells the model to call `search` first and gives seven worked examples, which is how I'd teach a free-form tool. All six carry `readOnlyHint`, `destructiveHint` and `idempotentHint`, with `search` read-only and `exec` not idempotent. The price of the design is that there's no schema to validate, since the input is code, and failures arrive as the thrown error text. A model that writes a bad `editor` call learns what broke from an exception rather than a message written for it. I'd ask for the commonest exception texts to be listed in the `exec` description. Four. The guidance is careful and the input still can't be validated. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
