Echo MCP Server: Bridging the Gap Between AI and Real-World Data with UBOS

In the rapidly evolving landscape of Artificial Intelligence, the ability for AI models to access and interact with real-world data is paramount. The Model Context Protocol (MCP) emerges as a crucial standard, streamlining how applications provide context to Large Language Models (LLMs). The Echo MCP Server is a minimal yet powerful implementation designed to facilitate this interaction, specifically for the Smithery framework. By acting as a bridge between AI models and external data sources, it unlocks new possibilities for intelligent applications. Integrate with UBOS platform to simplify AI Agent development.

Understanding the Model Context Protocol (MCP)

Before delving into the specifics of the Echo MCP Server, it’s essential to understand the core principles of the Model Context Protocol (MCP). MCP standardizes the way applications provide context to LLMs. This context can include data, instructions, or access to external tools. Without a standardized protocol, integrating AI models with various applications becomes a complex and time-consuming task. MCP solves this problem by providing a common language and structure for communication.

Imagine you’re building an AI-powered customer service agent. This agent needs access to customer data, order history, and product information to effectively assist customers. Without MCP, you would need to build custom integrations for each data source. With MCP, you can use a standardized protocol to connect the AI agent to any application that supports MCP.

The Echo MCP Server: A Minimal Implementation with Maximum Impact

The Echo MCP Server is designed to be a lightweight and easy-to-use implementation of the MCP standard. It provides a foundation for building more complex MCP servers and allows developers to quickly integrate AI models with their applications. Despite its simplicity, the Echo MCP Server offers a range of essential features:

Key Features

• Echo Tool: This basic tool simply returns the message it receives, useful for testing and basic communication.
• Ping Tool: Responds with “pong” upon invocation, serving as a health check and connection verification tool.
• Version Tool: Reports the server’s current version (“0.0.1”), crucial for managing updates and ensuring compatibility.
• MCP Streamable HTTP Transport: Implements the MCP Streamable HTTP Transport, adhering to the MCP standard for seamless data exchange.
• Zero Dependencies: Operates without external APIs, authentication mechanisms, or database connections, ensuring a lean and secure deployment.

The Echo MCP Server’s design emphasizes simplicity and ease of use, making it an ideal starting point for developers new to MCP. Its minimal dependencies reduce the risk of conflicts and simplify deployment, while its adherence to the MCP standard ensures interoperability with other MCP-compliant systems.

Installation and Setup

Setting up the Echo MCP Server is straightforward, requiring only Node.js and npm. The installation process involves a few simple steps:

1. Install Dependencies: Run npm install to install the necessary packages.
2. Start the Server: Execute npm start to launch the server on port 8000.
3. Access the Server: The server will be accessible at http://localhost:8000/mcp.

Once the server is running, you can begin testing its functionality using tools like MCP Inspector or cURL.

Testing the Echo MCP Server

The Echo MCP Server includes thorough testing instructions to ensure proper functionality. Two primary methods are available:

1. Using MCP Inspector

The MCP Inspector provides a graphical user interface for interacting with MCP servers, making it easy to test and debug your integrations.

• Install MCP Inspector: npm install -g @modelcontextprotocol/inspector
• Start MCP Inspector: npx @modelcontextprotocol/inspector streamable-http http://localhost:8000/mcp
• Access the UI: Open the Inspector UI at http://127.0.0.1:6274
• Configure the Connection:
  • Set Transport Type to “Streamable HTTP”
  • Set URL to http://localhost:8000/mcp
  • Click Connect

2. Using cURL

cURL is a command-line tool for making HTTP requests, providing a flexible way to interact with the MCP server.

• Initialize a Session:

  bash curl -v -X POST -H “Content-Type: application/json” -H “Accept: application/json, text/event-stream”
  -d ‘{“jsonrpc”:“2.0”,“method”:“initialize”,“params”:{“protocolVersion”:“2025-03-26”,“capabilities”:{},“clientInfo”:{“name”:“curl-client”,“version”:“1.0.0”}},“id”:1}’
  http://localhost:8000/mcp

• Send “initialized” Notification:

  bash curl -X POST -H “Content-Type: application/json” -H “Accept: application/json, text/event-stream”
  -H “mcp-session-id: YOUR_SESSION_ID”
  -d ‘{“jsonrpc”:“2.0”,“method”:“initialized”,“params”:{}}’
  http://localhost:8000/mcp

• List Available Tools:

  bash curl -X POST -H “Content-Type: application/json” -H “Accept: application/json, text/event-stream”
  -H “mcp-session-id: YOUR_SESSION_ID”
  -d ‘{“jsonrpc”:“2.0”,“method”:“tools/list”,“params”:{},“id”:2}’
  http://localhost:8000/mcp

• Call the Echo Tool:

  bash curl -X POST -H “Content-Type: application/json” -H “Accept: application/json, text/event-stream”
  -H “mcp-session-id: YOUR_SESSION_ID”
  -d ‘{“jsonrpc”:“2.0”,“method”:“tools/call”,“params”:{“name”:“echo”,“input”:{“message”:“hello”}},“id”:3}’
  http://localhost:8000/mcp

These testing methods allow you to verify the server’s functionality and ensure it is correctly integrated with your AI models.
