Go vs C¶
Both implementations expose identical MCP tools with identical behavior. Choose based on your environment.
Comparison¶
| Aspect | Go | C# Native AOT |
|---|---|---|
| Binary size | ~8-15 MB | ~20-40 MB |
| Startup time | ~10-50ms | ~50-100ms |
| Runtime dependency | None | None |
| Language | Go 1.26 | C# / .NET 10 |
| MCP SDK | Official go-sdk |
Official ModelContextProtocol |
| Cross-platform | Yes | Yes |
Both are compiled to native binaries with no external runtime dependency. Neither requires Go, .NET, Node.js, or Python to be installed.
Which Should I Choose?¶
Choose Go if: - You want the smallest binary (8-15 MB vs 20-40 MB) - You want fastest startup (useful if your AI tool spawns a new process per session) - You have no preference for a specific ecosystem
Choose C# if: - You're already in a .NET ecosystem and prefer C# tooling - You want to contribute to the codebase and prefer C# - You're evaluating Native AOT C# for your own projects
Both implementations pass the same tests and produce the same responses. The choice is purely a matter of preference and operational context.
