Trade Me MCP Server

A simple Model Context Protocol (MCP) server for integrating with Trade Me APIs through an external SDK.

Overview

This MCP server provides tools for interacting with Trade Me APIs. It's designed to work with Claude Code and other MCP-compatible applications.

Features

• Hello World: Basic connectivity test
• Server Info: Get information about the MCP server
• SDK Connection Test: Verify connection to Trade Me SDK wrapper
• Extensible: Ready for integration with your Trade Me API SDK

Prerequisites

This MCP server depends on a separate Trade Me SDK project that must be installed alongside it.

Required Project Structure

Both projects should be located in the same parent directory:

parent-folder/
├── trademe-sdk/          # Trade Me SDK project (required dependency)
└── trademe-tinymcp/      # This MCP server project

Installation

1. Ensure you have the Trade Me SDK project:

   • Clone the trademe-sdk project from: https://github.com/nzduck/trademe-sdk
   • Place it in the same parent directory as this project

2. Navigate to the project directory:

   cd trademe-tinymcp
   

3. Install dependencies using uv (recommended):

   uv sync
   

   Or using pip:

   pip install -e .
   

4. Install the Trade Me SDK dependency:

   pip install -e ../trademe-sdk
   

5. Install development dependencies (optional):

   uv sync --group dev
   

Quick Setup Script

For development, you can use the provided script to install both the SDK and MCP server:

bash src/scripts/update-sdk-mcp.sh

This script will:

• Activate the virtual environment
• Install the Trade Me SDK in editable mode from the sibling directory
• Install this MCP server in editable mode

Usage

Running the Server

Run the MCP server using the command-line interface:

python -m trademe_mcp.server

Or using the installed script:

trademe-mcp

Testing the Server

Test that the server is working correctly:

# Test basic functionality
python -c "
import asyncio
from trademe_mcp.server import mcp

async def test():
    # This would typically be done by an MCP client
    print('Server initialized successfully')

asyncio.run(test())
"

Integration with Claude Code

To use this MCP server with Claude Code, add it to your Claude Code configuration:

{
  "mcpServers": {
    "trademe": {
      "command": "python",
      "args": ["-m", "trademe_mcp.server"],
      "env": {}
    }
  }
}

Development

Project Structure

trademe-tinymcp/
├── src/trademe_mcp/
│   ├── __init__.py
│   ├── server.py          # Main MCP server implementation
│   └── sdk_wrapper.py     # Trade Me SDK wrapper (placeholder)
├── pyproject.toml         # Project configuration
├── README.md              # This file
└── .gitignore            # Git ignore rules

Available Tools

• hello_world(): Returns a simple greeting
• get_server_info(): Returns server metadata and available tools
• test_sdk_connection(): Tests the connection to the Trade Me SDK wrapper

Extending the Server

1. Replace the SDK wrapper: Update src/trademe_mcp/sdk_wrapper.py with your actual Trade Me SDK integration
2. Add new tools: Create new @mcp.tool() decorated functions in server.py
3. Add resources: Use @mcp.resource() decorators for data endpoints

Development Tools

Run linting and formatting:

# Format code
uv run black src/

# Lint code  
uv run ruff src/

# Run tests
uv run pytest

Troubleshooting

Common Setup Issues

1. "No module named 'trademe_sdk'" error:

   • Ensure the trademe-sdk project is in the correct location (sibling directory)
   • If missing, clone it from: https://github.com/nzduck/trademe-sdk
   • Install the SDK in editable mode: pip install -e ../trademe-sdk
   • Run the update script: bash src/scripts/update-sdk-mcp.sh

2. Script fails with path errors:

   • Verify the project structure matches the expected layout
   • Ensure both projects are in the same parent directory
   • Check that the virtual environment is activated

3. Claude Code integration issues:

   • Remember to start Claude Code from the virtual environment
   • Restart Claude Code after making changes to see updates

Requirements

• Python 3.10 or higher
• MCP SDK 1.2.0 or higher
• Trade Me SDK project (must be in sibling directory)
