JieBang Tools - MCP Server

A Model Context Protocol (MCP) Server providing 20+ online developer utilities, accessible via Streamable HTTP transport.

What is MCP?

The Model Context Protocol (MCP) is an open standard that enables AI models to securely interact with external tools and data sources. This project implements an MCP Server that exposes JieBang's developer tools as MCP tools, allowing any MCP-compatible AI client (Claude, Cursor, Windsurf, etc.) to directly use these utilities.

Quick Start

1. Register for an API Key

curl -X POST https://www.jiebang.site/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"email": "your@email.com", "password": "your-password"}'

Response:

{
  "api_key": "jb_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

2. Configure Your MCP Client

Add to your MCP client configuration (e.g., Claude Desktop, Cursor, Windsurf):

{
  "mcpServers": {
    "jiebang-tools": {
      "url": "https://www.jiebang.site/mcp",
      "headers": {
        "Authorization": "Bearer jb_your_api_key_here"
      }
    }
  }
}

3. Use the Tools

Once configured, your AI assistant can directly call any of the 20+ tools. For example:

• "Convert this JSON to YAML" → calls json-yaml
• "Generate a QR code for https://example.com" → calls qrcode
• "Check the SEO of example.com" → calls seo-check
• "What does the cron expression 0 9 * * 1-5 mean?" → calls cron-parse
