Dotnetmetadatamcpserver MCP Server

Most developer tooling work still happens through a UI a human drives. Dotnetmetadatamcpserver MCP server moves it into the conversation instead. A Model Context Protocol (MCP) server that provides detailed type information from .NET projects for AI coding agents.

The short version

The .NET Types Explorer MCP Server is a powerful tool designed to help AI coding agents understand and work with .NET codebases. It provides a structured way to explore assemblies, namespaces, and types in .NET projects, making it easier for AI agents to generate accurate and context-aware code suggestions.

• Assembly Exploration — Retrieve a list of all assemblies referenced by a .NET project
• Namespace Exploration — Discover all namespaces within specified assemblies
• Type Exploration — Get detailed information about types within specified namespaces, including:
• Full type names with generic parameters
• Implemented interfaces
• Constructors with parameters

The tools it exposes

The server publishes 5 tools. What each one is for:

• ReferencedAssembliesExplorer — Retrieves referenced assemblies based on filters and pagination
• NamespacesExplorer — Retrieves namespaces from specified assemblies supporting filters and pagination
• NamespaceTypes — Retrieves types from specified namespaces supporting filters and pagination
• NuGetPackageSearch — Searches for NuGet packages on nuget.org with support for filtering and pagination
• NuGetPackageVersions — Retrieves version history and dependency information for a specific NuGet package

What it needs from you

• .NET 10.0 SDK or later - A .NET project that you want to explore

Getting it running

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

How it compares

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Dotnetmetadatamcpserver's toolset — ReferencedAssembliesExplorer, NamespacesExplorer, NamespaceTypes and 2 more — is a fair guide to whether it matches your workflow. It is maintained by v0v1kkk; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Things to watch

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
