Full-featured MCP server for LINE WORKS (NAVER WORKS). CLI + MCP server — 26 tools covering messages, calendar, drive, mail, tasks, and boards.

Quickstart

npm install -g nworks
nworks login --user
nworks calendar list

AI Agents Actually Use It Like This

User: Show me today's schedule

Claude → nworks_calendar_list
  → 3 events: Standup (10:00), Lunch meeting (12:00), Code review (15:00)

User: Send a deploy complete message to the team channel

Claude → nworks_message_send
  { "channel": "C001", "text": "v1.2.0 deploy complete" }
  → Message sent

User: Check my unread emails and summarize them

Claude → nworks_mail_list (unread)
  → 3 unread emails
Claude → nworks_mail_read (each)
  → "3 unread: 1) Deploy approval from CTO, 2) Meeting invite for Friday, 3) Weekly report reminder"

Install

npx nworks             # Run directly
npm install -g nworks  # Global install

Login

# User OAuth (calendar, drive, mail, tasks, boards)
nworks login --user --scope "calendar calendar.read file file.read mail mail.read task task.read board board.read user.read"

# Bot messaging (Service Account)
nworks login

# Check auth status
nworks whoami

# Logout
nworks logout

> nworks login --user only requires CLIENTID + CLIENTSECRET. Values already set via environment variables or existing config won't be asked again.

> Developer Console: To use User OAuth, register http://localhost:9876/callback as a Redirect URL in the Developer Console.

AI Agent Integration (MCP Server)

Works with Claude Desktop, Cursor, and other MCP-compatible clients.

Setup

Login first:

nworks login --user --scope "calendar calendar.read file file.read mail mail.read task task.read board board.read user.read"

Then add to your MCP config (~/.config/claude/claude_desktop_config.json):

{
  "mcpServers": {
    "nworks": {
      "command": "nworks",
      "args": ["mcp"]
    }
  }
}

One login enables all 26 tools. No extra env setup needed.

> Without CLI login, an AI agent can call nworks_setup → nworks_login_user to authenticate via browser directly. Client Secret and Private Key path must be pre-configured via MCP config env field or system environment variables.

Environment Variables

Set environment variables to use nworks without nworks login (useful for CI/agents).

# Required
NWORKS_CLIENT_ID=
NWORKS_CLIENT_SECRET=

# Bot messaging only (not needed for User OAuth)
NWORKS_SERVICE_ACCOUNT=
NWORKS_PRIVATE_KEY_PATH=
NWORKS_BOT_ID=

# Optional
NWORKS_DOMAIN_ID=
NWORKS_SCOPE=              # default: bot bot.read user.read

MCP Server with Environment Variables

Sensitive values (Client Secret, Private Key path) must be set via MCP config env field. Non-sensitive values like Client ID can be configured by the AI agent through the nworks_setup tool.

{
  "mcpServers": {
    "nworks": {
      "command": "npx",
      "args": ["-y", "nworks", "mcp"],
      "env": {
        "NWORKS_CLIENT_SECRET": "",

    }
  }
