Exposing a Go App as Claude MCP Tools

Fri, 22 May 2026 00:00:00 +0000

The Model Context Protocol (MCP) lets Claude call external tools defined by your application. Instead of pasting data into a chat window or writing one-off scripts to query your system, you define tools with typed schemas, start an MCP server, and Claude can call them directly — in Claude Code, Claude Desktop, or any MCP-compatible client.

The Trader project uses this to expose its Forex trading engine as Claude tools: query your OANDA account, review open trades, run a backtest against historical data, and — when explicitly enabled — place or close orders.

Why Choose Go for Your Project?

Older project note. Kept for historical context; some implementation details may no longer reflect my current recommendations.

Go is simple

Go is easy to learn to program with and it is free! Go is much easier to maintain and deploy than Java.

Go does not have weird virtual environments of Python or npm, gulp, grunt, yarn, webpack (what’s next?) convoluted and complex build environments.

Go is Fast

It smokes most other languages, except the grand mother of Unix programming C. The Go programming language is almost as fast (performant geeky folks like to say) as C.
