Frequently asked questions
What is the Calendly MCP server and what can it do? +
The Calendly MCP server is hosted on Aerostack and exposes these tools to your AI agent: `_ping`, `get_current_user`, `get_organization`, `list_event_types`, `get_event_type`. You get one hosted URL — no self-hosting — that works from Claude, Cursor, ChatGPT, Gemini, VS Code, or any MCP-compatible client, and you can share it with your team or combine it with other MCP servers in a workspace.
Is the Calendly MCP server hosted, or do I have to run it myself? +
It's hosted on Aerostack's edge infrastructure — you don't deploy or maintain anything. Add it to a workspace and you get one authenticated URL, with secrets encrypted, that any AI agent or editor can connect to. Use it solo or share the same URL across your whole team.
Which AI agents and editors can use the Calendly MCP server? +
Any MCP client: Claude and Claude Code, Cursor, ChatGPT, Gemini, Windsurf, Cline, VS Code, and custom agents. Because it's one hosted URL, the same Calendly MCP server works everywhere — and you can compose it with other MCP servers, skills, and functions behind a single workspace URL.
How do I install the Calendly MCP server in Claude Desktop? +
Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-calendly": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-calendly"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.
How do I use the Calendly MCP server in Cursor? +
In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-calendly", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-calendly"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.
Does Calendly MCP require authentication? +
Yes. Calendly requires authentication. Check the MCP's documentation for the required credentials.
