Go vs C

Both implementations expose identical MCP tools and accept the same credentials. Choose based on your environment and preferences.

Comparison

	Go	C# Native AOT
Binary size	~12 MB	~20 MB
Startup time	< 5 ms	~20 ms
Memory usage	Lower	Slightly higher
Platforms	All	All
Runtime required	None	None
Transports	stdio, HTTP	stdio, HTTP

Both are self-contained native binaries -- no Go toolchain, no .NET runtime, no Node.js, no Python required. Both support the same HTTP transport with an equivalent Host allow-list security default; the only cosmetic difference is the HTTP status code returned for a disallowed host (403 for Go, 400 for C#, since C# uses ASP.NET Core's built-in Host Filtering Middleware as-is rather than custom logic).

When to Choose Go

• You prefer smaller binary sizes.
• You're deploying on resource-constrained machines where startup time matters.
• You want to build from source using only the Go toolchain.

When to Choose C

• You're already in a .NET ecosystem and prefer to build from source with dotnet publish.
• Your organization has tooling that works better with .NET binaries.

Which Binary Is Right for Most Users?

For AI assistant integration (GitHub Copilot, Claude, Cursor), either works fine. The server starts once and stays running -- the ~15 ms startup difference is imperceptible. Pick whichever binary matches the platform you're on (see the Getting Started download table).
