# Cal.com MCP server

> Manage Cal.com bookings, event types, schedules and availability from your AI assistant through the Cal.com API v2.

- Listing: https://mcp.tc/i/cal-com
- Connect: use the server's own URL `https://mcp.cal.com/mcp` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [Productivity & Projects](https://mcp.tc/c/productivity)
- Vendor: Cal.com
- Homepage: <https://cal.com/docs/mcp-server>

## About

Wraps the Cal.com API v2 so an assistant can work with scheduling data in natural language. The documentation lists tool groups for user profile, event types, bookings, schedules, availability and calendars, teams and memberships, organizations, and routing forms, plus an API catalog and documentation lookup.

The hosted server runs at https://mcp.cal.com/mcp over Streamable HTTP with OAuth 2.1. Your client starts a sign-in flow and you grant access to your Cal.com account, so no API key is needed. A self-hosted stdio option is also available through the @calcom/cal-mcp npm package with a CAL\_API\_KEY.

## What it can do

- Manage bookings on your Cal.com account
- Create and edit event types
- Work with schedules and availability
- Check calendars and connected calendar data
- Handle teams, memberships and organizations
- Work with routing forms
- Restrict tools per session using toolsets

## Example prompts

- "Show my upcoming Cal.com bookings for this week"
- "Create a 30 minute event type called Intro Call"
- "What availability do I have on Friday afternoon?"
- "List the members of my Cal.com team"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http cal-com https://mcp.cal.com/mcp
```

2. Start Claude Code, type `/mcp`, pick **cal-com** and choose **Authenticate**. A browser window opens for the Cal.com sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Cal.com** and paste this URL:

```url
https://mcp.cal.com/mcp
```

3. Click **Add**, then **Connect**, and sign in when Cal.com asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Cal.com&connectorUrl=https%3A%2F%2Fmcp.cal.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://mcp.cal.com/mcp` and click **Add**.

3. Click **Connect** and sign in when Cal.com asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://mcp.cal.com/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Cal.com to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=cal-com&config=eyJ1cmwiOiJodHRwczovL21jcC5jYWwuY29tL21jcCJ9>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "cal-com": {
      "url": "https://mcp.cal.com/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=cal-com&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.cal.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"cal-com","type":"http","url":"https://mcp.cal.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "cal-com": {
      "type": "http",
      "url": "https://mcp.cal.com/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "cal-com": {
      "serverUrl": "https://mcp.cal.com/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add cal-com --url https://mcp.cal.com/mcp
codex mcp login cal-com
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.cal-com]
url = "https://mcp.cal.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http cal-com https://mcp.cal.com/mcp
```

Then, inside Gemini CLI, run `/mcp auth cal-com` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "cal-com": {
      "type": "http",
      "url": "https://mcp.cal.com/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.cal.com/mcp`.
