Go vs C

Both the Go and C# implementations expose identical MCP tools with identical behavior and response formats. Pick based on your preferences.

Comparison

Aspect Go C# Native AOT
Binary size ~10--15 MB ~25--40 MB
Startup time ~10--50ms ~50--100ms
Runtime dependency None None
Language Go 1.26 C# / .NET 10
MCP SDK Official modelcontextprotocol/go-sdk Official ModelContextProtocol (.NET)
Auth implementation golang.org/x/oauth2/google Native RSA + HttpClient
AOT compiled Yes Yes (Native AOT)

Both binaries are fully self-contained. No Go toolchain, .NET runtime, Node.js, or Python is needed to run them.

Recommendation

Both work great. Pick Go for a smaller binary size. Pick C# if you're more comfortable with the .NET ecosystem or want to inspect/modify the source.

Naming Convention

Binary names follow this pattern:

gsc-mcp-{go|csharp}-{os}-{arch}[.exe]

Examples:

  • gsc-mcp-go-linux-amd64 -- Go, Linux x64
  • gsc-mcp-csharp-win-x64.exe -- C#, Windows x64
  • gsc-mcp-go-darwin-arm64 -- Go, macOS Apple Silicon

Tool Parity

If a feature is added to one implementation, it's added to both. The Go and C# versions are kept in sync. If you discover a behavioral difference between the two, please open an issue.
