Kalendis

What is Kalendis?

Kalendis is an MCP (Model Context Protocol) server and client generator that integrates the Kalendis scheduling API with AI agents like Claude and Cursor. It exposes scheduling API tools, generates TypeScript clients for backend and frontend applications, and creates API route handlers for popular frameworks.

How to use Kalendis?

Install via npm install @kalendis/mcp, then configure the MCP server in your IDE (e.g., Cursor) or manually in MCP settings. The generated tools (e.g., generate-backend-client, generate-api-routes) are then available for an AI agent to call. You need a free API key from kalendis.dev, but the MCP tool itself does not use the key — it only generates code that does.
