Raiqub.NuScope 1.4.7

NuScope

MCP server for exploring NuGet packages, metadata, and source code.

Configure in AI tools

NuScope runs as a stdio MCP server and can be started directly from NuGet with dnx. dnx is included with the .NET 10 SDK.

Use the NuGet package ID (Raiqub.NuScope) in the command arguments:

{
  "servers": {
    "nuscope": {
      "type": "stdio",
      "command": "dnx",
      "args": ["Raiqub.NuScope"]
    }
  }
}

For prerelease versions, add --prerelease. To pin a version, use Raiqub.NuScope@x.y.z.

Development

dotnet tool restore
dotnet restore --locked-mode
dotnet csharpier check .
dotnet build --configuration Release --no-restore
dotnet test --configuration Release --no-build --no-restore

Run the skeleton MCP server over stdio:

dotnet run --project src/NuScope.Server/NuScope.Server.csproj --no-build

Run the Aspire AppHost to launch MCP Inspector for the local server:

dotnet run --project src/NuScope.AppHost/NuScope.AppHost.csproj

Open the mcp-inspector endpoint from the Aspire dashboard.

NuScope remains a stdio-only MCP server. The AppHost starts MCP Inspector with:

npx -y @modelcontextprotocol/inspector dotnet run --project src/NuScope.Server/NuScope.Server.csproj

Open the mcp-inspector client endpoint from the Aspire dashboard, or browse to:

http://localhost:6284/?MCP_PROXY_PORT=6287&MCP_PROXY_AUTH_TOKEN=<token>

The AppHost uses ports 6284 and 6287 to avoid stale MCP Inspector browser storage from the default localhost:6274 origin. The Aspire dashboard client link includes a per-run proxy authentication token.
