toggl-track-mcp-server

toggl-track-mcp-server

TypeScript MCP server (stdio) exposing tools to fetch Toggl Track v9 time entries.

Features

• Single‑day time entry fetch using Toggl v9 (/api/v9/me/time_entries).
• Timezone aware via Temporal polyfill (@js-temporal/polyfill):
  • Accepts any IANA timezone (e.g. Asia/Tokyo, America/New_York).
  • If timezone is omitted, uses your Toggl account timezone (fetched via /api/v9/me), with fallback to UTC.

Directory Layout

• src/index.ts – MCP server bootstrap (registers tools)
• src/tools/ – Tool implementations
  • ping.ts
  • get_time_entries_for_date.ts
  • check_auth.ts
• src/toggl/ – Toggl API client
  • get.ts (fetchTimeEntriesForDateV9, fetchMe)
• src/utils/ – Utilities
  • config.ts (env loader)
  • date.ts (Temporal‑based dayRange)
• src/schemas/ – Zod and shared types
  • date.ts, toggl.ts, tools.ts

Environment

1. Copy .env.template to .env and set values:

cp .env.template .env

Required

• TOGGL_API_TOKEN

Notes

• .env is auto‑loaded via dotenv/config.
• You can also pass the token via MCP client env.

Build

npm i
npm run build

Run (stdio)

node dist/index.js --transport stdio

Use with Claude Desktop

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

{
  "mcpServers": {
    "toggl-track": {
      "command": "/opt/homebrew/bin/node",
      "args": [
        "--enable-source-maps",
        "/Users/yourname/path/to/toggl-track-mcp-server/dist/index.js",
        "--transport",
        "stdio"
      ],
      "env": {
        "TOGGL_API_TOKEN": "YOUR_TOKEN",
        "TZ": "Asia/Tokyo"
      }
    }
  }
}

Use with MCP Inspector

npx @modelcontextprotocol/inspector

• Add Server → Stdio
  • Command: node (or absolute node path)
  • Args: /path/to/dist/index.js --transport stdio
  • Env: TOGGL_API_TOKEN=..., TZ=Asia/Tokyo

Tools

• ping

  • Returns ok.

• check_auth

  • Verifies token via /api/v9/me and returns a masked summary.
  • Params: none (uses TOGGL_API_TOKEN from env).

• get_time_entries_for_date

  • Fetches v9 time entries for a single date.
  • Params (JSON):
    • date (string, optional; accepts YYYY-MM-DD, YYYY/MM/DD, 今日, 昨日, 一昨日; omitted means today)
    • timezone (string, IANA; optional → uses account timezone; fallback UTC)
    • apiToken (string; optional override for env)
  • Returns (JSON):
    • { meta: { source: 'v9', date, timezone, startUTC, endUTC, count }, entries: [...] }

Notes

• This project uses Node ESM with module: nodenext. Write relative imports with .js extensions in source.
• Timezone math uses Temporal via @js-temporal/polyfill.
