I want to set up the eBay MCP Server for my AI assistant. Please help me:

1. Install the eBay MCP server:
   npm install -g ebay-mcp

2. I need to configure it for [Claude Desktop / Cursor / Cline / Zed / Continue.dev / Windsurf / Claude Code CLI / Amazon Q] (choose one)

3. My eBay credentials are:
   - Client ID: [YOUR_CLIENT_ID]
   - Client Secret: [YOUR_CLIENT_SECRET]
   - Environment: [sandbox / production]
   - Redirect URI (RuName): [YOUR_REDIRECT_URI]

Please:
- Create the appropriate config file for my MCP client
- Set up the environment variables
- Help me complete the OAuth flow to get a refresh token for higher rate limits
- Test that the connection works

If I don't have eBay credentials yet, guide me through creating a developer account at https://developer.ebay.com/

Visual Setup Guide

The setup wizard (npm run setup) handles OAuth authentication automatically. Here's where to find your credentials in the eBay Developer Portal:

Finding Your Credentials

Step 1: Navigate to eBay Developer Portal and copy your App ID (Client ID) and Cert ID (Client Secret):

Step 2: In your app's User Tokens settings, copy the RuName (eBay Redirect URL):

Running the Setup Wizard

Run npm run setup and enter your credentials when prompted. The wizard will:

1. Open your browser for OAuth login automatically
2. Guide you through the eBay sign-in process

3. Ask you to paste the authorization code from the callback URL

4. Exchange the code for tokens and save them automatically
5. Configure your MCP client (Claude Desktop, etc.)

Success! You now have user token authentication with 10k-50k requests/day instead of the default 1k/day.

4. Use

Restart your MCP client (Claude Desktop, etc.) and start using eBay tools through your AI assistant.
