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
HTTP mode	Stateless	Stateless
Default listener	127.0.0.1:8080	127.0.0.1:8080
HTTP endpoints	/mcp, /health	/mcp, /health

Both are self-contained native binaries. Both implement the same shared HTTP contract, including Host and Origin validation. The only cosmetic difference is the disallowed-Host status code (403 for Go and 400 for C#).

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).
