Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@lists Create a list called Groceries and add bananas and coffee."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Lists with items — create a list, add to it, check things off, delete them.
One SQLite store and one HTTP service, shared by three surfaces: a web app, an iOS app, and the MCP tools. Every write goes through the service, so the three cannot disagree about what a save means.

pnpm test # store + service
pnpm typecheckThe service requires BARRY_SECRET: Authorization: Bearer <secret> (or
x-barry-secret) on every /api/ route, whatever address the request comes
from, since every hosting provider connects from loopback. /health never
takes auth, so a probe can tell "server down" from "wrong secret". It refuses
to start without a secret.

barry ios build lists --deviceOn a device it reaches the service through whatever your installation's
hosting.yaml exposes it on (a private tunnel, say); the address and the
secret are both editable in Settings. How the service is reached from off this
Mac is installation policy, not this bag's: see barry hosting status lists.web.
A public route to it must be gated, since the origin's only auth is the secret.
