What it does

Reads and writes Google Calendar events, including multi-calendar availability. The valuable part is the read path — answering 'when are we all free' without a scheduling thread. Writes need OAuth against your own account, so an agent can book over your evening if it misreads a timezone.

Install

Terminal

npx -y @cocal/google-calendar-mcp

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

mcp.json

{
  "mcpServers": {
    "google-calendar": {
      "command": "npx",
      "args": [
        "-y",
        "@cocal/google-calendar-mcp"
      ]
    }
  }
}

Use it for

Checking availability and creating events from a conversation

Skip it if

Editing other people's calendars without saying so

When to use it

Reach for this when the task needs calendar inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.
