### Step 1: Create LINE Official Account
This MCP server utilizes a LINE Official Account. If you do not have one, please create it by following [this instructions](https://developers.line.biz/en/docs/messaging-api/getting-started/#create-oa).
If you have a LINE Official Account, enable the Messaging API for your LINE Official Account by following [this instructions](https://developers.line.biz/en/docs/messaging-api/getting-started/#using-oa-manager).
### Step 2: Configure AI Agent
Please add the following configuration for an AI Agent like Claude Desktop or Cline.
Set the environment variables or arguments as follows:
- `CHANNEL_ACCESS_TOKEN`: (required) 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).
- `DESTINATION_USER_ID`: (optional) The default user ID of the recipient. If the Tool's input does not include `user_id`, `DESTINATION_USER_ID` is required. You can confirm this by following [this instructions](https://developers.line.biz/en/docs/messaging-api/getting-user-ids/#get-own-user-id).

## Local Development with Inspector
You can use the MCP Inspector to test and debug the server locally.
### Prerequisites
1. Clone the repository:
```bash
git clone git@github.com:line/line-bot-mcp-server.git
cd line-bot-mcp-server
```
2. Install dependencies:
```bash
npm install
```
3. Build the project:
```bash
npm run build
```
### Run the Inspector
After building the project, you can start the MCP Inspector:
```bash
npx @modelcontextprotocol/inspector node dist/index.js
```
This will start the MCP Inspector interface where you can interact with the LINE Bot MCP Server tools and test their functionality.
