## About

A local MCP server for NuGet, the package manager for .NET. It is published by the NuGet team and lives in the mcp folder of the NuGet Home repository, so an assistant can help with NuGet package tasks in .NET development.

It runs locally over stdio from the NuGet.Mcp.Server package (version 1.4.16) and is launched with dnx, which needs a recent .NET SDK. The registry lists no environment variables or remote endpoint, and no sign-in details are documented.

## What it can do

- Runs locally as a stdio MCP server
- Connects an assistant to NuGet package management
- Distributed as the NuGet.Mcp.Server package

## Example prompts

- "Help me manage NuGet packages in my .NET project"
- "Which NuGet package should I use for JSON handling in .NET?"
- "Check whether my project's NuGet dependencies can be updated"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport stdio microsoft-nuget -- dnx NuGet.Mcp.Server --yes
```

2. Start Claude Code and type `/mcp`. **microsoft-nuget** should show as connected.

Add `--scope user` to make it available in every project.

### Claude Desktop

1. Open **Settings → Developer → Edit Config**. It opens `claude_desktop_config.json`. Add:

`claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "microsoft-nuget": {
      "command": "dnx",
      "args": [
        "NuGet.Mcp.Server",
        "--yes"
      ]
    }
  }
}
```

2. Save the file and restart Claude Desktop.

Needs .NET 10 on your computer. The file lives in `~/Library/Application Support/Claude/` on macOS and `%APPDATA%\Claude\` on Windows.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=microsoft-nuget&config=eyJjb21tYW5kIjoiZG54IiwiYXJncyI6WyJOdUdldC5NY3AuU2VydmVyIiwiLS15ZXMiXX0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "microsoft-nuget": {
      "command": "dnx",
      "args": [
        "NuGet.Mcp.Server",
        "--yes"
      ]
    }
  }
}
```

Needs .NET 10 on your computer.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=microsoft-nuget&config=%7B%22type%22%3A%22stdio%22%2C%22command%22%3A%22dnx%22%2C%22args%22%3A%5B%22NuGet.Mcp.Server%22%2C%22--yes%22%5D%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"microsoft-nuget","type":"stdio","command":"dnx","args":["NuGet.Mcp.Server","--yes"]}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "microsoft-nuget": {
      "type": "stdio",
      "command": "dnx",
      "args": [
        "NuGet.Mcp.Server",
        "--yes"
      ]
    }
  }
}
```

Needs .NET 10 on your computer.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "microsoft-nuget": {
      "command": "dnx",
      "args": [
        "NuGet.Mcp.Server",
        "--yes"
      ]
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf.

### Codex

```bash
codex mcp add microsoft-nuget -- dnx NuGet.Mcp.Server --yes
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.microsoft-nuget]
command = "dnx"
args = ["NuGet.Mcp.Server", "--yes"]
```

Needs .NET 10 on your computer.

### Gemini CLI

```bash
gemini mcp add microsoft-nuget dnx -- NuGet.Mcp.Server --yes
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients that start local servers accept this shape:

```json
{
  "mcpServers": {
    "microsoft-nuget": {
      "command": "dnx",
      "args": [
        "NuGet.Mcp.Server",
        "--yes"
      ]
    }
  }
}
```

Zed puts servers under `context_servers` in its settings, with the same `command`, `args` and `env` fields.
