MCPServer + CoinGecko Wrapper: A Comprehensive MCP Server Solution

Overview: What is MCPServer?

MCPServer is an essential component in the Model Context Protocol (MCP) infrastructure, designed to facilitate communication between various AI applications and data sources through a standardized protocol. It serves as the central hub for handling incoming requests from compatible AI clients, processing them accordingly, and delivering structured responses.

🔧 Core Features & MCP Capabilities

Key Components:

• mcpserver (PHP): The core server that manages all MCP interactions.

  • Core Directory (core/): Contains essential logic for reusability.
  • Capabilities File (capabilities.php): Defines which tools the server can utilize.
  • Webhook Endpoint (webhook.php): Serves as the primary entry point to receive and process MCP requests.

• mcp-coingecko-wrapper (Node.js + TypeScript): A tool that provides cryptocurrency data using CoinGecko's API.

  • Index File (src/index.ts): Houses the primary logic for exposing API endpoints.
  • Package Configuration (package.json): Manages dependencies and scripts.

Functionality:

• mcpserver (PHP)

  • Receives MCP requests in JSON format.
  • Routes requests based on tool_choice.
  • Interacts with specified tools, such as the CoinGecko wrapper.
  • Returns structured MCP responses for client processing.

• mcp-coingecko-wrapper (Node.js + TypeScript)

  • Exposes HTTP endpoints compatible with the MCP protocol.
  • Fetches and provides real-time cryptocurrency data from CoinGecko API.
  • Supports operations like obtaining current prices, general information, and historical price data.

⚙️ MCP Architecture & Protocol Implementation

Workflow:

1. AI Application Request: An AI application (e.g., Claude) sends an MCP request containing specific details such as tool_choice and input parameters.
2. MCPServer Reception: The webhook.php endpoint of MCPServer processes the incoming MVC request.
3. Tool Selection & Data Fetching: Based on tool_choice, MCPServer invokes the appropriate tool (e.g., mcp-coingecko-wrapper).
4. Response Sending: The requested data or action is performed, and an MCP-compliant response is sent back to the client.

🚀 Getting Started with Installation

Quickstart Guide:

1. Install Dependencies for the Wrapper:

   cd mcp-coingecko-wrapper
   npm install
   npm run build
   

2. Serve MCPServer Using a PHP Server (e.g., XAMPP, Apache):

💡 Key Use Cases in AI Workflows

Case 1: Real-Time Cryptocurrency Price Monitoring

• Scenario: An investment firm needs real-time cryptocurrency prices for trading decisions.
• Implementation: The firm integrates the MCPServer with its existing financial platform. Users send an MCP request to webhook.php specifying tool_choice: "coingecko" and input: { symbol: "bitcoin", operation: "price_now" }. Upon receiving a positive response, the firm updates their trading interface accordingly.

Case 2: Automated Data Collection for Research

• Scenario: A university research group requires frequent price data to analyze trends in cryptocurrency markets.
• Implementation: The researchers create an MCP client that periodically sends requests to the MCPServer. Using the mcp-coingecko-wrapper, they gather and store comprehensive price data over time, which is then analyzed for research purposes.
