Hellocast in Claude

How to connect

In Claude, add Hellocast from the connector directory, or add a custom connector with the server URL https://hellocast.app/api/mcp. Then:

• Sign in to Hellocast in the browser window that opens (OAuth, no API key needed).
• Check the agent name and return address, choose the organization and approve access. Uncheck content editing if the agent should only read.
• Go back to Claude and ask it to list your screens.

What the agent can do

Eight tools: read the organization context, list screens, list playlists, read a playlist, create a playlist, add a text or visual-design slide, edit such a slide, and assign a playlist to a screen. Slides can have a schedule in your organization’s timezone.

• “List my screens and show which playlist each one plays.”
• “Show me the slides in the reception TV’s playlist.”
• “Add a text slide saying ‘Welcome to our office’ to the reception playlist, for 15 seconds.”

What it can’t do

The connection cannot delete content, manage your team or billing, pair new screens, upload files or use Hellocast’s AI slide design. A playlist change appears on every screen that uses that playlist.

Access, privacy and support

Each connection is limited to one organization and lasts up to 90 days. You can revoke it any time in Hellocast under Settings → Agent connections; owners can revoke any connection in their organization. The server only reads and writes your Hellocast content and never asks for your conversations. Data stays on our servers in the Netherlands, see the privacy policy. Questions: hello@hellocast.app.

Questions

Which agents work?

Any agent that supports remote MCP servers with browser sign-in (OAuth) and automatic client registration, such as Claude. Connections that only accept a static API key are not supported.

Do I need Pro?

No. The connector works on the free plan too.
