WebMCP in the editor
WebMCP will let an AI agent in your browser read and edit an open Womp project. Not open to all accounts yet.Use this when: you use a browser agent that supports WebMCP and want it to work in a Womp project.
Don't use this for: reading the docs. Use llms.txt and the Markdown pages.
WebMCP is a proposed web API (a W3C community group draft) that lets a page give tools to an AI agent running in the browser. In Womp it is not open to all accounts yet; this page describes it ahead of release. The Womp editor registers its tools when you open a project you can edit, while you are signed in and the 3D view is connected. They are not available in print mode.
Tools
| Tool | What it does |
|---|---|
set_scene_view | Frames the scene in the viewport |
get_scene_edit_prompt | Reads how to edit a Womp scene. Read only |
execute_javascript | Edits the scene by running code in the page |
execute_javascript runs in the page with your permissions. Only use agents you trust with your projects.
The tools are available only while you are signed in and can edit the project.
Use instead
- Wrong move: giving an untrusted agent access to a project with WebMCP. Why:
execute_javascriptis not sandboxed from the page. Right move: use Spark (Womp AI), which edits your scene inside Womp.
