    How to connect

    How to connect opointo to Claude

    The server address to paste into Claude settings:

    https://opointo.com/api/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect opointo to ChatGPT

    The server address to paste into ChatGPT settings:

    https://opointo.com/api/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    Authorization

    Server tool list (11)

    Raw names from tools/list. Only developers need these.

    find_componentFinds the component for a UI need described in plain words, ranked, and says when this catalog ships nothing on purpose because the phone's own control is the right choice. Omit `need` to list every component with its purpose and whether it renders the real system control.
    get_componentEverything needed to write a correct call site for one component: props with types, defaults and allowed values, what draws on iOS and on Android, the providers it needs at the app root, its dependencies, and the runtime rules that stop it rendering blank.
    check_snippetScans TSX that uses these components for the mistakes that render nothing with no error: animated opacity on glass, the flex: 1 collapse, a clipped lens, a conditionally mounted surface. A read-only text scan, not a guarantee; verify_app checks a whole emitted project.
    get_app_setupHow an app is set up so these components work and follow its theme, one topic at a time: the app-root providers in the order that works, the theme hooks and token scales, or the rules that hold across the whole catalog. An app built by emit_app already has all three wired.
    emit_appNeeds a subscription. Turns a design from the Designer into a working Expo app: navigation, providers, tab bar, screens and the components they use. Returns a recipe for the current project: every file with its target path, one install line and ordered steps with a check each. Pass `step` for one step in full, which does not count against the daily allowance.
    add_screenNeeds a subscription. Adds one screen designed in the Designer to a project. With the project's .opointo/files.json it returns the screen file, the route that mounts it and the one line to register it, and never rewrites existing files. Without it, a self-contained screen file for any Expo app.
    install_componentNeeds a subscription, except for the free foundation components. Adds one component to an existing project: the files it and its dependencies need in install order with exact target paths, the single expo install line, the providers it needs and its runtime rules. A backend recipe's id, such as "supabase", adds that integration: its files and the per-app wiring an export writes.
    update_componentsNeeds a subscription. Reads the project's .opointo/files.json and returns only the opointo-supplied files that changed since export, so it works months later with no share code. Never touches the customer's own screens, and flags the rare change that needs a code edit rather than a copy.
    verify_appNeeds a subscription. Checks an emitted app before it is built: missing files, altered verbatim files, absent packages, the expo-router config merge, whether the installed Xcode can build it, and whether a change needs a new native build.
    propose_appYour agent can design an app with you: send an app in opointo's design format (the AppSpec emit_app builds from) and get back a link that opens it in the Designer as a new, unsaved design. The person sees every screen, changes what they like, and hands it back for emit_app. into: the code in the person's line; it lands in their open design. dryRun checks without making a link; format: true returns the format and every block, "photos" the sample photos, or with app: { version: 1 } a short plan's.
    propose_screenYour agent can design a single screen with you: send one screen in opointo's design format (the Composition add_screen builds from) and get back a link that opens it in the Designer as a new, unsaved design the person can change. into: as propose_app's. dryRun checks without making a link; format: true returns the format. For a whole app, use propose_app.
