CastHub MCP Server

Model Context Protocol server for digital signage. Manage TV fleets, presentations, schedules, and emergency alerts from Claude, Cursor, ChatGPT, or any MCP client.

What this is

CastHub MCP Server lets AI assistants directly control digital signage networks. Instead of clicking through a dashboard, you tell Claude to update the lobby TV, push an emergency alert to all stores, or schedule next week's promotional content. The server exposes 30+ tools covering devices, presentations, schedules, alerts, and groups across the CastHub platform.

Why this exists

Digital signage management is repetitive, multi-step work that maps cleanly to natural language. Several signage platforms (Fugo, Revel Digital, Screenly) have shipped MCP support over the last year. CastHub MCP differentiates on hosted endpoint architecture (no local install required for the basic path), a governance layer with preview-confirm-rollback for safe agent use, and native Amazon Signage Stick integration.

Two ways to connect

Option A: Hosted endpoint (recommended)

No installation required. Add the CastHub MCP server to your Claude Desktop, Cursor, or other MCP client config:

{
  "mcpServers": {
    "casthub": {
      "url": "https://api.cast-hub.com/mcp",
      "auth": {
        "type": "bearer",
        "token": "YOUR_CASTHUB_API_KEY"
      }
    }
  }
}

Generate your API key at dashboard.cast-hub.com.

Option B: Install the SDK locally

For MCP clients that require a local stdio process:

npm install -g @cast-hub/mcp

Then configure your client:

{
  "mcpServers": {
    "casthub": {
      "command": "casthub-mcp",
      "env": {
        "CASTHUB_API_KEY": "your-api-key-here"
      }
    }
  }
}

The SDK forwards MCP protocol calls to the CastHub hosted endpoint. All tool execution happens server-side; the SDK is a transport shim.
