GitHub - amornpan/py-mcp-line: python mcp LINE

A Model Context Protocol server implementation in Python that provides access to LINE Bot messages. This server enables Language Models to read and analyze LINE conversations through a standardized interface.

• Asynchronous operation using Python's asyncio
• Environment-based configuration using python-dotenv
• Comprehensive logging system
• LINE Bot webhook event handling
• Message storage in JSON format
• FastAPI integration for API endpoints
• Pydantic models for data validation
• Support for text, sticker, and image messages

• Python 3.8+
• Required Python packages:
  • fastapi
  • pydantic
  • python-dotenv
  • mcp-server
  • line-bot-sdk
  • uvicorn

Create a .env file in the project root:

LINE_CHANNEL_SECRET=your_channel_secret
LINE_ACCESS_TOKEN=your_access_token
SERVER_PORT=8000
MESSAGES_FILE=data/messages.json

@app.list_resources()
async def list_resources() -> list[Resource]

• Lists available message types from the LINE Bot
• Returns resources with URIs in the format line://<message_type>/data
• Includes resource descriptions and MIME types

@app.read_resource()
async def read_resource(uri: AnyUrl) -> str

• Reads messages of the specified type
• Accepts URIs in the format line://<message_type>/data
• Returns messages in JSON format
• Supports filtering by date, user, or content

Add to your Claude Desktop configuration:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "line": {
      "command": "python",
      "args": [
        "server.py"
      ],
      "env": {
        "LINE_CHANNEL_SECRET": "your_channel_secret",
        "LINE_ACCESS_TOKEN": "your_access_token",
        "SERVER_PORT": "8000",
        "MESSAGES_FILE": "data/messages.json"
      }
    }
  }
}

The server implements comprehensive error handling for:

• Webhook validation failures
• Message storage errors
• Resource access errors
• URI validation
• LINE API response errors

All errors are logged and returned with appropriate error messages.

• Environment variable based configuration
• LINE message signature validation
• Proper error handling
• Input validation through Pydantic
