Which integrations are available for this server?

Provides tools for interacting with the LINE Messaging API, enabling AI agents to send messages (text, image, sticker, flex, video, audio, location), manage groups and rooms, configure rich menus, and query analytics such as follower counts and message statistics.

How do I use @zients/line-mcp-server?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@@zients/line-mcp-server Broadcast a text message to all followers" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Prerequisites

Node.js >= 22
A LINE Official Account with Messaging API enabled
Channel Access Token

Create a LINE Official Account

Go to LINE Official Account Manager and create an account
Go to LINE Developers Console and log in
Create a Provider (or select an existing one)
Under the Provider, create a Messaging API Channel linked to your Official Account
Go back to LINE Developers Console, select your Provider and Channel
In the Basic settings tab, find Your user ID (U...) — for testing push messages to yourself
Go to the Messaging API tab, scroll to the bottom, and click Issue under Channel access token (long-lived) to generate your token

Enable Group/Room Features (Optional)

To use group/room tools or send messages to groups and rooms:

In LINE Official Account Manager → Settings → Account settings → enable Allow bot to join groups
In LINE Official Account Manager → Settings → Response settings → enable Webhook
In LINE Developers Console → your Channel → Messaging API tab → set your Webhook URL
Invite the bot to a group or room in the LINE app (search by the bot's Basic ID @xxx shown in LINE Developers Console → Basic settings)
To get the ID, receive the join event or any message event via Webhook — it will contain source.groupId (for groups) or source.roomId (for rooms)

Setup (npx — recommended)

No installation needed — just configure your MCP client.

DEFAULT_UID is optional. Set it when you want single-target messaging tools to use a default LINE User ID, so calls like push_text_message can omit to.

Codex CLI

codex mcp add @zients/line-mcp-server \
  --env CHANNEL_ACCESS_TOKEN=<your-token> \
  --env DEFAULT_UID=U... \
  -- npx -y @zients/line-mcp-server

Start a new Codex session after adding the MCP server so Codex loads the new tools.

Claude Code

claude mcp add @zients/line-mcp-server -t stdio \
  -e CHANNEL_ACCESS_TOKEN=<your-token> \
  -e DEFAULT_UID=U... \
  -- npx -y @zients/line-mcp-server

OpenClaw (mcporter)

mcporter config add @zients/line-mcp-server \
  --command npx \
  --arg -y --arg @zients/line-mcp-server \
  --env CHANNEL_ACCESS_TOKEN=<your-token> \
  --env DEFAULT_UID=U... \
  --description "LINE Messaging API tools"

Other MCP clients

Add the following to your MCP client configuration:

{
  "mcpServers": {
    "@zients/line-mcp-server": {
      "command": "npx",
      "args": ["-y", "@zients/line-mcp-server"],
      "env": {
        "CHANNEL_ACCESS_TOKEN": "<your-token>",
        "DEFAULT_UID": "U..."
      }
    }
  }
}

Setup (build from source)

git clone https://github.com/zients/line-mcp-server.git
cd line-mcp-server
npm install
npm run build   # compiles TypeScript to dist/

Codex CLI

codex mcp add @zients/line-mcp-server \
  --env CHANNEL_ACCESS_TOKEN=<your-token> \
  --env DEFAULT_UID=U... \
  -- node /path/to/line-mcp-server/dist/index.js

Claude Code

claude mcp add @zients/line-mcp-server -t stdio \
  -e CHANNEL_ACCESS_TOKEN=<your-token> \
  -e DEFAULT_UID=U... \
  -- node /path/to/line-mcp-server/dist/index.js

OpenClaw (mcporter)

mcporter config add @zients/line-mcp-server \
  --command node \
  --arg /path/to/line-mcp-server/dist/index.js \
  --env CHANNEL_ACCESS_TOKEN=<your-token> \
  --env DEFAULT_UID=U... \
  --description "LINE Messaging API tools"

Verify & call tools (mcporter)

mcporter list @zients/line-mcp-server --schema
mcporter call @zients/line-mcp-server.push_text_message to=U... text="Hello"
mcporter call @zients/line-mcp-server.push_text_message text="Hello from DEFAULT_UID"
mcporter call @zients/line-mcp-server.get_user_profile userId=U...
mcporter call @zients/line-mcp-server.get_bot_info

After registration, Claude can call LINE tools directly:

"Send 'Hello' to my LINE group C1234567890"

Environment Variables

Variable	Required	Description
`CHANNEL_ACCESS_TOKEN`	Yes	LINE Messaging API channel access token
`DEFAULT_UID`	No	Default recipient User ID (must start with `U`). When set, the single-target messaging tools (`push_text_message`, `push_image_message`, `push_sticker_message`, `push_flex_message`, `push_video_message`, `push_audio_message`, `push_location_message`, `show_loading_indicator`) may omit `to`/`chatId` and send to this user by default. An explicit `to` (User/Group/Room) always overrides it. If set to a value that does not start with `U`, the server exits on startup.

TDQS

A3.6/5.0

Scored 2026-09-04 10:30 across 44 tools

Disambiguation5/5

Every tool has a clearly distinct purpose, with clear prefixes for messaging (push, broadcast, multicast), retrieval (get), and management (create, delete, set, etc.). The target audience (user, group, room) is specified in descriptions, eliminating confusion. Parallel tools for groups and rooms are distinct by entity type.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern in snake_case, using predictable prefixes like push_, get_, create_, list_, delete_, set_, cancel_, link_, unlink_, leave_, and show_. This uniformity makes the toolset easy to navigate and understand.

Tool Count4/5

With 44 tools, the server is on the heavier side, but the breadth of LINE Official Account functionality (messaging, rich menus, group/room management, analytics) justifies the count. Each tool serves a distinct purpose, and the structure is logical, so it does not feel excessive for the domain.

Completeness4/5

The toolset covers core messaging (push, broadcast, multicast), rich menu CRUD, group/room info, and analytics. However, there are notable gaps: reply messages are missing, and broadcast/multicast are only available for text and flex, not for image/video/audio/location/sticker. These are missing but workable around, so overall completeness is strong but not perfect.
