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 |
Both are self-contained native binaries -- no Go toolchain, no .NET runtime, no Node.js, no Python required.
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).
