⚙️ MCP Architecture & Protocol Implementation

Model Context Protocol (MCP) Overview

Model Context Protocol is a standardized communication protocol that allows AI applications and services to interact with specific data sources and tools. This server implements key aspects of the MCP, including command execution, environment setup, and interaction protocols for GitHub repositories.

Protocol Implementation Details

The protocol flow can be understood through the following simplified diagram:

    A[AI Application] -->|MCP Client| B[MCP Protocol]
    B --> C[MCP Server]
    C --> D[GitHub API/Repository]

This diagram illustrates how AI applications pass requests via MCP clients, which then interact with the Model Context Protocol to perform operations on GitHub repositories.
