LINE and this assistant

The same counter, on your own official account

This page shows the part of a broadcast channel that is actually difficult: an assistant that knows exactly which notices exist, changes only the one named, and reads a signed-in follower's own subscriptions back instead of asking which list they think they are on.

1. Point the assistant at your site so your own notices, rhythms and membership levels become the answers it gives, as published content rather than a re-typed copy. 2. Expose the follower list as a small MCP server: the notices that exist, a lookup by reference and email, and a read that only answers for the signed-in person. 3. Give the subscription tool an action card, so a change is one tap on the right notice instead of a sentence somebody has to interpret. 4. Put the consent rules in the assistant's own instructions rather than in a policy page — never adding an unasked notice is a behaviour, not a paragraph. 5. Link the official account last. The add-as-friend step is cheap; being worth keeping after it is the part that takes the work above.

What runs on this page

The assistant in the thread is a live Busymate AI assistant, grounded in this site's own published pages.
The notice list, the membership levels and the subscription states come from this demo's own MCP server — real tool calls, not pasted text.
The page registers its own actions over WebMCP, so an agent can highlight a notice or open the subscription form.
Signing in as the demo follower is a real identity hand-off: the assistant receives a name and an email address it never asked for.

What is seeded rather than connected

There is no LINE official account behind this page. Nothing here is broadcast, nothing is added to anybody's friend list, and no LINE service is contacted at any point.
Tsukumo Camera is an invented shop. The address, the telephone number, the email, the staff, the stock, the prices and the subscriptions are all fictional — nothing here dials or reaches anybody.
Subscription changes made here live in memory until this demo restarts. No list is written to and nobody is sent anything.
