Tempo MCP — Calendar and Time Tracking for Agents

What it is

Tempo MCP is a Model Context Protocol server that gives AI agents access to calendar and time tracking functionality. It integrates with Google Calendar for scheduling and availability, and with Toggl for time logging.

Tempo MCP targets developers building AI assistants that need to manage schedules, block focus time, check meeting availability, or log work hours -- all through natural language commands.

How it saves time or tokens

Instead of switching between calendar apps, time trackers, and chat interfaces, Tempo MCP lets you ask your AI agent questions like 'What meetings do I have today?' or 'Log 3 hours of coding.' The agent handles the API calls directly. Token estimate is approximately 3200 tokens per session.

How to use

1. Add Tempo MCP to your MCP config:

{
  "mcpServers": {
    "tempo": {
      "command": "npx",
      "args": ["-y", "tempo-mcp-server"],
      "env": {
        "GOOGLE_CALENDAR_CREDENTIALS": "/path/to/credentials.json",
        "TOGGL_API_TOKEN": "your-token"
      }
    }
  }
}

1. Restart your AI client (Claude Code, Cursor, etc.).

1. Ask your agent about your schedule or log time entries.

Example

# Natural language commands your agent can handle:
'What meetings do I have today?'
'Block 2 hours for deep work tomorrow morning'
'Log 3 hours of coding on the TokRepo project'
'When am I free this week for a 1-hour meeting?'
'Cancel my 3pm meeting and notify attendees'

Common pitfalls

• Google Calendar credentials require OAuth setup through the Google Cloud Console. The credentials.json file must have Calendar API access enabled.
• Toggl API tokens are personal and workspace-scoped. Ensure you use the correct token for the workspace where you want to log time.
• Calendar operations may fail silently if the agent lacks permission to modify events created by others.
