ASP.NET Core Debugging MCP Server
The cross-platform .NET debugging MCP — runs on Linux, macOS, and Windows.
An MIT-licensed MCP server that lets an AI agent (Claude, etc.) debug your .NET / ASP.NET Core app — netcoredbg bundled for every platform, nothing extra to install.
Instead of "I think the bug is around line 42, try this", the agent runs your code, pauses it, reads the actual runtime values, mutates state to test a fix, and answers grounded in what it actually saw.

Why is my EF Core query returning empty?
You
GET /users/activereturns[], but I know there are active users in the DB. What's the query actually doing?
