Band MCP Server

This project aims to build a Model Context Protocol (MCP) server that integrates with the Band API. The server will allow users to fetch posts from their Band groups and perform read/write operations on Band data using the Band API. The server will be implemented in TypeScript and deployed using Docker.

Objectives

1. OAuth 2.0 Authentication: Use the Band API's OAuth 2.0 flow to authenticate users and obtain access tokens.
2. Fetch Posts: Provide an MCP resource to fetch posts from a user's Band groups.
3. Read/Write Operations: Implement MCP tools to read and write data to Band groups using the Band API.
4. MCP Integration: Expose Band API functionality through MCP primitives such as resources and tools.
5. Docker Deployment: Package the MCP server into a Docker container for easy deployment.

Features

• OAuth 2.0 Authorization: Securely authenticate users and manage access tokens.
• MCP Resources: Fetch and expose Band posts as MCP resources.
• MCP Tools: Enable read/write operations on Band data via MCP tools.
• TypeScript Implementation: Leverage TypeScript for type safety and maintainability.
• Dockerized Deployment: Simplify deployment with a Docker container.

Quick Start

Prerequisites

• Node.js 18+ installed
• TypeScript knowledge
• Understanding of OAuth 2.0 authorization flows
• Basic knowledge of Docker and containerization
• Access to the Band API and developer credentials

Installation

# Clone the repository
git clone <repository-url>
cd band-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

# Start the server
npm start

Testing

# Run unit tests
npm test

# Test the MCP server manually
node dist/index.js

Architecture

The Band MCP Server consists of several key components:

• MCP Server Core: Handles MCP protocol communication
• OAuth 2.0 Module: Manages user authentication and token handling
• Band API Client: Interfaces with the Band API
• Resource Handlers: Exposes Band data as MCP resources
• Tool Handlers: Implements read/write operations as MCP tools

Configuration

Create a .env file in the project root:

BAND_CLIENT_ID=your_band_client_id
BAND_CLIENT_SECRET=your_band_client_secret
BAND_REDIRECT_URI=http://localhost:3000/callback

Usage

The server exposes the following MCP capabilities:

Resources

• band://posts/{group_id} - Fetch posts from a specific Band group
• band://groups - List user's Band groups

Tools

• create_post - Create a new post in a Band group
• update_post - Update an existing post
• delete_post - Delete a post
• get_group_info - Get information about a Band group

Docker Deployment

# Build the Docker image
docker build -t band-mcp-server .

# Run the container
docker run -p 3000:3000 --env-file .env band-mcp-server
