Echo Server: Integrating Voice-to-Text Conversion via MCP Protocol

Overview: What is Echo Server?

The Echo Server is an MCP-based tool designed to enable seamless voice-to-text conversion and data retrieval from YouTube videos using advanced AI capabilities. By leveraging the Model Context Protocol (MCP), this server provides a standardized interface for integrating various AI applications, ensuring robust compatibility across different workflows.

🔧 Core Features & MCP Capabilities

The Echo Server offers several critical features that enhance its usability as an MCP client:

• Voice-to-Text Conversion: Real-time transcription of audio content.
• YouTube Video Transcripts: Accurate retrieval and management of video transcripts.
• Standardized Protocol: Adherence to the MCP protocol ensures seamless communication across different AI applications.

Implementation Details

The Echo Server integrates directly with the Model Context Protocol by implementing key functions such as:

• Command Execution: Runs commands using npx for server deployment and configuration.
• Environment Variables: Sets necessary environment variables like API_KEY, crucial for correct functioning within an MCP ecosystem.

⚙️ MCP Architecture & Protocol Implementation

The Echo Server's architecture is built upon a robust MCP framework, ensuring seamless integration with other applications. The primary components include:
