Overview

AI-generated overview

Read-only remote MCP access to Slottable: contacts, bookable slot types, dated slots, rosters, bookings and webhooks.

What you can do
  • List and fetch contacts, including the most recent booking contacts with their details
  • List and fetch slot types with duration, price and booking rules
  • List and fetch dated slot instances with datetime, capacity, price and publish state
  • List the roster and the bookings of a given dated slot
  • List and fetch webhook subscriptions with target URL, model, events and filter
  • Check monthly usage, request a missing feature, upgrade or cancel the subscription
When to use it
Useful when you want an assistant to answer questions about a Slottable company's services, upcoming slots, who is registered, recent bookings and webhook setup, without opening the Slottable dashboard.
Requirements
Remote endpoint at slottable.usefulapi.io over streamable HTTP; no local install. Sign-in is via OAuth, and on first connect you supply your Slottable company API token from the company's Integrations & API settings. No API key or Authorization header goes in the client config.
Before you install
The server stores your Slottable company API token per user after validating it. Data tools are read-only, but the meta tools can start a paid Stripe Checkout subscription (Pro $9/month or $90/year, Pro+ $39/month or $390/year) and cancel Pro; the free plan is limited to 50 tool calls per month. Contact details and booking data are sent to the hosted service and to your AI client.

Installation

In SourceWeft

  1. Open Slottable MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fslottable/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

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:
json
{  "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.
