Market Price Finder MCP Server written in TypeScript (Cloudflare Workers Deployment)

This project is a Model Context Protocol (MCP) server built on Cloudflare Workers that helps find and compare market prices for products. It provides tools for querying and analyzing product prices across different marketplaces.

An MCP server is a specialized server that implements the Model Context Protocol, allowing AI models to interact with external tools and services. In this case, our server provides tools for market price analysis.

Features

Query product prices from various marketplaces
Compare prices across different vendors
Real-time price updates
No authentication required for basic usage

Option 2: Local Development

To set up the project locally, follow these steps:

Create a new project using the template:

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

Install dependencies:

cd my-mcp-server npm install

Start the development server:

npm run dev

Customizing the Server

Adding New Tools

You can extend the server's functionality by adding your own tools:

Open src/index.ts
Locate the init() method
Add new tools using this.server.tool(...)

For more information about creating tools, check the MCP tools documentation.

Using the Server

Method 1: Cloudflare AI Playground

The easiest way to interact with your MCP server is through the Cloudflare AI Playground:

Visit Cloudflare AI Playground
In the connection settings, enter your server URL:
- For deployed server: remote-mcp-server-authless.<your-account>.workers.dev/sse
- For local development: http://localhost:8787/sse
Start using the market price finder tools through the playground interface

Method 2: Claude Desktop Integration

You can also use the server with Claude Desktop:

Install the MCP remote proxy:

npm install -g mcp-remote

Configure Claude Desktop:

Open Claude Desktop
Go to Settings > Developer > Edit Config
Update the configuration:

{ "mcpServers": { "market-finder": { "command": "npx", "args": [ "mcp-remote", "http://localhost:8787/sse" // Use your deployed URL for production ] } } }
