Microsoft NuGet MCP Server

com.microsoft/nuget

Bring NuGet package management into AI agent workflows via MCP.

What is the Microsoft NuGet MCP server?

Microsoft NuGet MCP server is a Model Context Protocol server, distributed as the NuGet.Mcp.Server package, that exposes NuGet package manager functionality to AI agents. It is part of the NuGet Home project maintained by the .NET Foundation, which provides the NuGet client tools and NuGet.org package repository for the Microsoft/.NET development platform. The README provided is primarily the general NuGet Home project overview rather than detailed MCP tool documentation.

The Microsoft NuGet MCP server connects AI coding assistants to NuGet, the package manager for .NET and the Microsoft development platform. It is installed via the NuGet.Mcp.Server NuGet package. The provided README documents the broader NuGet Home repository (docs, design proposals, contributing guidelines, and related repos like NuGet.Client and NuGetGallery) rather than the specific MCP tool set, so concrete tool capabilities are not detailed here.
