toggl-mcp

A Model Context Protocol (MCP) server that gives Claude access to your Toggl Track time tracking data.

Ask Claude things like:

• "What am I tracking right now?"
• "How much time did I spend on each project this week?"
• "Start a timer for writing documentation on the Blog project"
• "Stop my timer"
• "What did I work on yesterday?"

Tools

| Tool | What it does | |------|-------------| | get_current_timer | Shows the currently running time entry | | get_recent_entries | Time entries for the past N days (default 7) | | get_projects | Lists all your projects | | get_summary | Total time by project for a date range | | start_timer | Starts a new time entry | | stop_timer | Stops the current timer | | get_profile | Your Toggl profile and workspaces |

Setup

1. Get your API token

1. Go to https://track.toggl.com/profile
2. Scroll to the bottom
3. Click "Click to reveal" under API Token
4. Copy the token

2. Install

npm install -g toggl-mcp

Find the installed path:

which toggl-mcp

3. Add to Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "toggl": {
      "command": "/path/from/which/toggl-mcp",
      "env": {
        "TOGGL_API_TOKEN": "your_token_here"
      }
    }
  }
}

Or if running from source:

{
  "mcpServers": {
    "toggl": {
      "command": "node",
      "args": ["/path/to/toggl-mcp/dist/index.js"],
      "env": {
        "TOGGL_API_TOKEN": "your_token_here"
      }
    }
  }
}

Restart Claude Desktop. You should see a green "running" badge in Settings → Developer.

Rate limits

Toggl's free plan allows 30 requests/hour per workspace. This MCP server batches calls where possible (e.g. fetching projects and entries in parallel) to stay well within limits for normal use.
