## Installation
### Step 1: Install line-bot-mcp-server
requirements:
- Node.js v20 or later
Clone this repository:
```
git clone git@github.com/line/line-bot-mcp-server.git
```
Install the necessary dependencies and build line-bot-mcp-server when using Node.js. This step is not required when using Docker:
```
cd line-bot-mcp-server && npm install && npm run build
```
### Step 2: Get a channel access token
This MCP server utilizes a LINE Official Account. If you do not have one, please create it by following [this instructions](https://www.linebiz.com/jp-en/manual/OfficialAccountManager/new_account/).
To connect to the Messaging API, you need to have a channel access token. You can confirm this by following [this instructions](https://developers.line.biz/en/docs/basics/channel-access-token/#long-lived-channel-access-token).
Additionally, you will need the user ID of the recipient user for messages. You can confirm this by following [this instructions](https://developers.line.biz/en/docs/messaging-api/getting-user-ids/#get-own-user-id).
### Step 3: Configure AI Agent
Please add the following configuration for an AI Agent like Claude Desktop or Cline.
Insert the channel access token and user ID you obtained earlier into `CHANNEL_ACCESS_TOKEN` and `DESTINATION_USER_ID`, respectively.
Additionally, update the path to `line-bot-mcp-server` in `mcpServers.args`.
