Debugs and tests C# Model Context Protocol (MCP) servers locally using IDEs, MCP Inspector, and GitHub Copilot.

This skill provides a comprehensive workflow for developers building AI agents with .NET, focusing on the local execution and troubleshooting of Model Context Protocol (MCP) servers. It guides users through configuring VS Code and Visual Studio for breakpoint debugging, using the MCP Inspector for protocol-level testing, and verifying tool discovery within GitHub Copilot Agent Mode. By emphasizing correct logging practices and configuration of stdio and HTTP transports, it helps developers quickly resolve common JSON-RPC communication errors and registration issues.
