What is Calendly Universal MCP Server?

The Calendly Universal MCP Server is an implementation of a Universal MCP (Model Context Protocol) server designed to provide a standardized interface for interacting with Calendly's tools and services through a unified API. It allows for managing events and scheduling via Calendly, ensuring compatibility with other MCP-compliant services and tools.

How to use Calendly Universal MCP Server?

There are two primary ways to use the Calendly Universal MCP Server:

• Through agentr.dev: You can directly use Calendly by visiting agentr.dev and enabling Calendly from agentr.dev/apps. If you are new to Universal MCP, follow the setup instructions at agentr.dev/quickstart.
• Local Development: For local development, you need Python 3.11+ and uv. After installing uv, sync project dependencies with uv sync, activate the virtual environment, start the MCP Inspector with mcp dev src/universal_mcp_calendly/server.py, and then install the application with mcp install src/universal_mcp_calendly/server.py.

Local Development

📋 Prerequisites

Ensure you have the following before you begin:

• Python 3.11+ (recommended)
• uv (install globally with pip install uv)

🛠️ Setup Instructions

Follow the steps below to set up your development environment:

1. Sync Project Dependencies

   uv sync
   

   This installs all dependencies from pyproject.toml into a local virtual environment (.venv).

2. Activate the Virtual Environment

   For Linux/macOS:

   source .venv/bin/activate
   

   For Windows (PowerShell):

   .venv\Scripts\Activate
   

3. Start the MCP Inspector

   mcp dev src/universal_mcp_calendly/server.py
   

   This will start the MCP inspector. Make note of the address and port shown in the console output.

4. Install the Application

   mcp install src/universal_mcp_calendly/server.py
