DotNet Types Explorer MCP server

This is a helper for people who work with .NET code and want their AI assistant to actually understand it. It lets the AI look inside your project's compiled code and tell you what classes, methods, and packages are there. It is handy if you write or read .NET code and want fewer wrong guesses from your AI.

What this MCP server does

You point the helper at a .NET project on your computer. When you ask your AI something about that project, the AI sends the question to this helper. The helper opens the compiled code and reads the list of assemblies, namespaces, and types inside. It can also search nuget.org for packages and check their versions. Then it sends the details back, and your AI explains them to you in the chat.

What you can do with it

• List all the assemblies your .NET project uses
• Show every namespace inside a chosen assembly
• Describe the classes, methods, properties, and events in a namespace
• Search nuget.org for packages by name or keyword
• Check the version history and dependencies of a NuGet package
• Narrow results with filters and page through large lists

Try asking your AI

• “What assemblies does my project reference?”
• “Show me the namespaces inside the Newtonsoft.Json assembly.”
• “List the public methods of the types in the System.Text.Json.Serialization namespace.”
• “Search NuGet for a package called Serilog and show me its recent versions.”

What it gives back to you

You get back plain lists and descriptions in the chat: assembly names, namespace names, and details about types like their methods, properties, and constructors. NuGet searches come back as a list of matching packages with version details. Nothing in your code is changed; it only reads and reports.
