NugetMcpServer

NugetMcpServer is an MCP server that helps you find and inspect NuGet packages. It gives you accurate information about interfaces, classes, enums, and other types directly from the packages. This helps AI assistants provide better code suggestions and avoid making up non-existent APIs.

Certified by MCPHub.

Overview

This server connects your AI assistant (like Claude or Copilot) to the real NuGet ecosystem. Instead of guessing, the AI can look up the exact methods and types available in a specific version of a package.

You can use it to:

• Find the right package for your task.
• See the exact interface definitions.
• Check for breaking changes between versions.
• Get correct code examples based on real metadata.

It works with any client that supports the Model Context Protocol (MCP), such as VS Code (with Copilot), Claude Desktop, or OllamaChat.

Supported Clients

• VS Code: Integrate through MCP server configuration
• OllamaChat: My experimental C# AI playground built on Semantic Kernel. It features RAG, image analysis support, multi-agent chat (e.g., philosophers debating), and MCP server support with automatic function selection via vector indexes. Check it out at OllamaChat.
• GitHub Copilot: Use as an MCP server to get accurate package information
• Other MCP Clients: Any tool that supports the Model Context Protocol

Quick Start

Option 1: Docker (Recommended)

Prerequisite: Docker installed and running.

Click to Install in VS Code (Docker)

Option 2: .NET Tool (Native)

Prerequisite: .NET 9.0 SDK installed.

1. Install the tool globally:

   dotnet tool install -g DimonSmart.NugetMcpServer
   

2. Click to Install in VS Code (Local)

Option 3: Claude Desktop

Run this command to install automatically via Smithery:

npx -y @smithery/cli install @dimonsmart/nugetmcpserver --client claude

Option 4: Manual Configuration

If you prefer to configure manually:

Docker Configuration

{
  "mcpServers": {
    "nuget": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "ghcr.io/dimonsmart/nugetmcpserver:latest"]
    }
  }
}

.NET Tool Configuration

{
  "mcpServers": {
    "nuget": {
      "command": "NugetMcpServer",
      "args": []
    }
  }
}

Private & Local NuGet Sources

You can point the server at private feeds (Azure Artifacts, Artifactory, ProGet, Nexus) and local folders.

Source resolution order (highest priority first):

1. --source / --sources command-line args
2. NUGET_SOURCES + NUGET_CONFIG environment variables
3. NuGet:Sources + NuGet:ConfigPath in appsettings.json (or client env binding)
4. Default NuGet con
