Add the Cal.com MCP server to VS Code

Config last verified Jun 1, 2026

The exact config to run Cal.com in VS Code — paste it in, restart, and the tools load.

Prerequisites

VS Code installed.
CAL_API_KEY — Cal.com API key for the local stdio server (the remote endpoint uses OAuth instead).

Setup

1. Open `.vscode/mcp.json`

2. Add this configuration

Add to .vscode/mcp.json

.vscode/mcp.json

json

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

3. Restart VS Code and confirm the Cal.com tools load.

Gotchas

VS Code is the exception to every other client: its top-level key is "servers", not "mcpServers", and each entry needs an explicit "type" (for example "http" or "stdio"). Secrets are not inlined; instead you declare an "inputs" array and reference each value as ${input:id}, so VS Code prompts for it once and never writes it to disk. Remote servers connect natively with OAuth.
