What is an MCP server?
MCP (Model Context Protocol) is an open standard from Anthropic that connects AI assistants to external tools and data sources. An MCP server exposes capabilities - reading databases, creating records, calling APIs - that AI models use during conversations.
How it works in online booking
Calendesk built an open-source MCP server for appointment booking with 41 tools. An AI assistant like Claude checks available time slots, creates bookings, pulls client details, and runs analytics - all through natural conversation. You ask "Which Saturday next month has the most open slots?" and get a real answer from live booking data. The MCP server works alongside other AI-powered integrations in the Calendesk ecosystem.
Benefits
- 41 ready-to-use tools covering bookings, clients, services, and analytics via AI chat
- Open source on GitHub - inspect the code, extend it, or run it on your own server
- Compatible with Claude, ChatGPT, and any AI assistant supporting the MCP protocol
Frequently Asked Questions
What can you do with the Calendesk MCP server?
It exposes 41 tools for bookings, clients, employees, services, availability, analytics, and notifications. Ask an AI assistant to "book a consultation for next Thursday at 2 PM" or "show revenue for Q1" and it runs the action through the MCP server in real time.
Does the MCP server require technical setup?
About 10 minutes of work. Clone the repository from GitHub, add your Calendesk API key to the config file, and connect it to your AI assistant (like Claude Desktop). Step-by-step docs are included. After that initial setup, you interact with your booking system entirely through natural language.
