ASP.NET Core Debugger — MCP Server For AI Agents
Give your coding agent interactive breakpoints, stacks, and variable inspection for .NET and ASP.NET Core apps.
Overview
ASP.NET Core Debugger MCP Server is a MCP server for the Build phase that lets AI agents debug .NET and ASP.NET Core applications interactively via netcoredbg and DAP.
What is this MCP server?
- Interactive .NET / ASP.NET Core debugging exposed as MCP tools
- Uses netcoredbg with Debug Adapter Protocol (DAP)
- NuGet package AspNetCoreDebuggerMcp 1.0.0 with dnx runtimeHint
- stdio transport for agent-driven debug sessions
- Open-source repo magna-nz/aspnetcore-debugger-mcp on GitHub
- Version 1.0.0 on NuGet registry api.nuget.org
- stdio transport with dnx runtimeHint
- GitHub repository: magna-nz/aspnetcore-debugger-mcp
Community signal: 7 GitHub stars.
What problem does it solve?
Agents frequently misdiagnose ASP.NET Core bugs because they cannot attach a real debugger or inspect runtime state.
Who is it for?
.NET solo devs using AI agents who need interactive debugging on ASP.NET Core APIs or web apps during implementation.
Skip if: JavaScript-only stacks, production-only observability needs, or teams unwilling to run netcoredbg locally.
What do I get? / Deliverables
After registration, your agent can drive DAP-backed debug sessions—breakpoints, stepping, and inspection—against your .NET host process.
- Agent-controlled interactive debug session against a .NET process
- DAP-backed inspection workflow integrated into agent tooling

How it compares
Runtime debugger MCP over DAP, not a static analyzer or Azure-hosted remote debug portal.
Common Questions / FAQ
Who is io.github.magna-nz/aspnetcore-debugger-mcp for?
Indie and small-team .NET developers who want Claude Code or Cursor to debug ASP.NET Core with real breakpoints and DAP.
When should I use io.github.magna-nz/aspnetcore-debugger-mcp?
Use it while building or fixing backend .NET services when logs and tests are not enough and you need live inspection.
How do I add io.github.magna-nz/aspnetcore-debugger-mcp to my agent?
Add the stdio MCP server using the NuGet identifier AspNetCoreDebuggerMcp via dnx and point your client at the published 1.0.0 package.
