magna-nz/aspnetcore-debugger-mcp

Overview

An MCP server that enables AI agents like Claude and Cursor to debug .NET and ASP.NET Core applications. It provides a bridge between AI tools and the .NET debugger, allowing agents to inspect state, set breakpoints, and step through code.

Best for

Best for
.NET developers who want to debug applications using AI agents like Claude or Cursor

Use cases

Use cases

• Debugging .NET applications via natural language commands in Claude or Cursor
• Inspecting variable values and call stacks during AI-assisted development
• Automating breakpoint management and step-through debugging in CI workflows

Pros

• Integrates AI agents directly with .NET debugging workflows
• Open source with a permissive license for customization
• Lightweight C# implementation with minimal dependencies

Cons

• Requires running an MCP-compatible AI agent (Claude, Cursor) to function
• Limited to .NET / ASP.NET Core applications only
• Small community and limited documentation due to low star count
