Add it

In Claude: Settings → Connectors → Add custom connector. Any client that speaks the Model Context Protocol (MCP) takes the same address.
You sign in with GitHub when you add it, which is what makes the widgets you build yours.
How a session goes
- Ask about whatever you are working through. It does not have to be something the library already covers.
- When a widget fits, it appears in the chat with its check, and the explanation is built around something you can move.
- When none fits, your assistant writes one — one claim, one interactive view, one check — and it runs in the conversation straight away.
- You publish it or discard it.
Why publish
Everything here was written by someone working through what you are working through. Publishing is free and reversible: the widget goes into the library under your name, and it is what the next person asking the same question gets instead of a fresh explanation that disappears.
The tools
find_widget- Searches by meaning; returns the closest widgets, or a brief for writing one.
get_widget- One widget with its check, lineage, related widgets and source.
submit_widget- Submits a new widget, or a new version of one of yours.
assent- Publishes or discards a draft you own.
What the connector stores is in the privacy page; you can revoke its access from your account.
