LINE Bot MCP Server

Connects an AI agent to a LINE Official Account using the LINE Messaging API.

Model Context Protocol (MCP)server implementation that integrates the LINE Messaging API to connect an AI Agent to the LINE Official Account.

[!NOTE] This repository is aforkof the officialLINE Bot MCP Serverwithadditional SSE (Server-Sent Events) transport support. The original repository only supports stdio transport.

- Original Repository:line/line-bot-mcp-server
- Fork Enhancement: Added SSE transport support for web-based integrations
- Docker Image: Available on Docker Hub asacquojp/line-bot-mcp-server-sse:latest

[!NOTE] This repository is provided as a preview version. While we offer it for experimental purposes, please be aware that it may not include complete functionality or comprehensive support.

This MCP server supports multiple transport protocols:

- stdio(default): Standard input/output for local integrations
- SSE: Server-Sent Events over HTTP for web-based integrations
- push_text_message

- Push a simple text message to a user via LINE.
- Inputs:

- user_id(string?): The user ID to receive a message. Defaults to DESTINATION_USER_ID. Eitheruser_idorDESTINATION_USER_IDmust be set.
- message.text(string): The plain text content to send to the user.

- Push a highly customizable flex message to a user via LINE.
- Inputs:

- user_id(string?): The user ID to receive a message. Defaults to DESTINATION_USER_ID. Eitheruser_idorDESTINATION_USER_IDmust be set.
- message.altText(string): Alternative text shown when flex message cannot be displayed.
- message.content(any): The content of the flex message. This is a JSON object that defines the layout and components of the message.
- message.contents.type(enum): Type of the container. 'bubble' for single container, 'carousel' for multiple swipeable bubbles.

- Broadcast a simple text message via LINE to all users who have followed your LINE Official Account.
- Inputs:

- message.text(string): The plain text content to send to the users.

- Broadcast a highly customizable flex message via LINE to all users who have added your LINE Official Account.
- Inputs:

- message.altText(string): Alternative text shown when flex message cannot be displayed.
- message.content(any): The content of the flex message. This is a JSON object that defines the layout and components of the message.
- message.contents.type(enum): Type of the container. 'bubble' for single container, 'carousel' for multiple swipeable bubbles.

- Get detailed profile information of a LINE user including display name, profile picture URL, status message and language.
- Inputs:

- user_id(string?): The ID of the user whose profile you want to retrieve. Defaults to DESTINATION_USER_ID.

- Get the message quota and consumption of the LINE Official Account. This shows the monthly message limit and current usage.
- Inputs:

- None

- Get the list of rich menus associated with your LINE Official Account.
- Inputs:

- None

- Delete a rich menu from your LINE Official Account.
- Inputs:

This MCP server utilizes a LINE Official Account. If you do not have one, please create it by followingthis instructions.

If you have a LINE Official Account, enable the Messaging API for your LINE Official Account by followingthis instructions.

- CHANNEL_ACCESS_TOKEN: (required) Channel Access Token. You can confirm this by followingthis instructions.
- DESTINATION_USER_ID: (optional) The default user ID of the recipient. If the Tool's input does not includeuser_id,DESTINATION_USER_IDis required. You can confirm this by followingthis instructions.
- MCP_TRANSPORT: (optional) Transport protocol to use. Options:stdio(default),sse
- MCP_PORT: (optional) Port for SSE transport. Default:3000

{ "mcpServers": { "line-bot": { "command": "npx", "args": [ "@line/line-bot-mcp-server" ], "env": { "CHANNEL_ACCESS_TOKEN" : "FILL_HERE", "DESTINATION_USER_ID" : "FILL_HERE" } } } }

{ "mcpServers": { "line-bot": { "command": "npx", "args": [ "@line/line-bot-mcp-server" ], "env": { "CHANNEL_ACCESS_TOKEN" : "FILL_HERE", "DESTINATION_USER_ID" : "FILL_HERE", "MCP_TRANSPORT" : "sse", "MCP_PORT" : "3000" } } } }

For SSE transport, the server will start an HTTP server with the following endpoints:

- GET /sse- Establish SSE connection
- POST /messages- Send messages to the server
- GET /health- Health check endpoint

Option A: Use Pre-built Docker Image (Recommended)

You can use the pre-built Docker image from Docker Hub without building locally:

# Pull the latest image docker pull acquojp/line-bot-mcp-server-sse:latest # Run directly docker run --rm -p 3000:3000 \ -e CHANNEL_ACCESS_TOKEN="your_token" \ -e DESTINATION_USER_ID="your_user_id" \ acquojp/line-bot-mcp-server-sse:latest

This MCP server utilizes a LINE Official Account. If you do not have one, please create it by followingthis instructions.

If you have a LINE Official Account, enable the Messaging API for your LINE Official Account by followingthis instructions.

git clone https://github.com/your-username/line-bot-mcp-server.git

docker build -t line-bot-mcp-server-sse .

- mcpServers.args: (required) The path toline-bot-mcp-server.
- CHANNEL_ACCESS_TOKEN: (required) Channel Access Token. You can confirm this by followingthis instructions.
- DESTINATION_USER_ID: (optional) The default user ID of the recipient. If the Tool's input does not includeuser_id,DESTINATION_USER_IDis required. You can confirm this by followingthis instructions.
- MCP_TRANSPORT: (optional) Transport protocol to use. Options:stdio(default),sse
- MCP_PORT: (optional) Port for SSE transport. Default:3000
