Slottable MCP by usefulapi

Slottable MCP by usefulapi

Use your Slottable account from Claude, Cursor, or any MCP client. It reads contacts, slot types, dated slots, rosters, bookings and webhook subscriptions, and it changes nothing. Hosted, no local install: connect with your own credentials.

Live endpoint: https://slottable.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://slottable.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http slottable https://slottable.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "slottable": {
      "url": "https://slottable.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Slottable credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/slottable/

On first connect you provide your Slottable company API token (Slottable → Integrations & API in the company settings). The server validates it and stores it per user. No keys go in config files.
