eBay MCP server

This MCP server provides a simple way to fetch auctions from eBay.com through the Model Context Protocol. It allows natural language queries to search for eBay listings and returns structured results from eBay's REST API.

Installation

Prerequisites

The server requires UV, a fast Python package and project manager.

If UV isn't already installed on your system, you can install it with:

# Using Homebrew on macOS
brew install uv

Or alternatively:

# On macOS and Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# On Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Installing the MCP Server

Once UV is installed, you can install the eBay MCP server directly from the source repository:

uv pip install git+https://github.com/CooKey-Monster/EbayMcpServer.git

Required Environment Variables

Before using the server, you need to set up the following environment variables:

• CLIENT_ID: Your eBay client ID
• CLIENT_SECRET: Your eBay client secret

You can obtain these credentials from the eBay developer portal.

Usage

Available Tools

The server provides a single tool:

• list_auction: Scans eBay for auctions based on a search query

Tool Parameters

• query (required): The search query string (e.g., "batman comics")
• ammount (optional): Number of results to return (defaults to 0)

Example Queries

You can use natural language prompts to search for eBay auctions, such as:

• "Find me 10 auctions for batman comics"
• "Search for vintage cameras on eBay"
• "List the top auctions for Nintendo Switch games"

The server will process these requests using the eBay REST API and return the auction listings in a structured format.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
