How does assembly resolution work?

Assemblies can be resolved from the build output directory, the NuGet global packages cache, or automatically try both modes.

Can I configure multiple NuGet package sources?

Yes, you can configure multiple enabled NuGet v3 sources in appsettings.json, which are queried in parallel with priority-based deduplication.

Is a full project build required to explore assemblies?

Not necessarily; using the NuGetCache mode allows exploring assemblies from the NuGet cache without a full build, only requiring 'dotnet restore'.

How does the server handle duplicate packages from multiple sources?

It uses the order of sources in configuration as priority, with the first source taking precedence for metadata and deduplication.

Overview

This MCP server enables AI agents to explore .NET projects by extracting detailed type metadata from compiled assemblies using reflection. It supports browsing assemblies, namespaces, and types including methods, properties, fields, and events. Additionally, it integrates with NuGet to search packages, retrieve version histories, and resolve dependencies. Use it to provide AI coding assistants with structured .NET API context for code generation or analysis.
