Go Runtime FAQs

Question 1

What is Go Runtime and how does it help Go developers?

Accepted Answer

Go Runtime (go-runtime-mcp) is an MCP server that empowers AI agents (like Claude) to inspect and diagnose live Go application runtime metrics, including goroutines, heap memory, and garbage collection behavior, directly from its built-in debug endpoint. It translates complex runtime data into plain English diagnoses, automating troubleshooting.

Question 2

How does Go Runtime integrate with AI agents?

Accepted Answer

It integrates with MCP Hosts like Claude Desktop, Claude Code, or Cursor. These LLM environments communicate with the Go Runtime server via JSON-RPC over stdio. The AI agent calls specific tools within Go Runtime, which then fetches data from your Go app's debug endpoint, processes it, and returns structured JSON output with both machine-readable fields and human-readable diagnoses for the LLM to interpret.

Question 3

What problem does Go Runtime solve compared to manual debugging?

Accepted Answer

Traditionally, diagnosing Go runtime issues involves SSHing into a server, manually hitting `/debug/pprof`, parsing raw output, and forming hypotheses. Go Runtime automates this by allowing an AI agent to perform these steps, interpret the output, and provide a diagnosis in plain English, significantly streamlining the debugging process for memory growth, goroutine leaks, or GC pauses.

Question 4

What specific Go metrics can Go Runtime analyze?

Accepted Answer

Go Runtime can inspect the current goroutine count and detect potential leaks, analyze detailed heap memory statistics (Alloc, TotalAlloc, HeapInuse) for growth investigations, monitor garbage collection (GC) behavior (frequency, timestamps), and retrieve full goroutine stack traces with optional keyword filtering for deep analysis.

Question 5

Is it safe to use Go Runtime with a production Go application?

Accepted Answer

Yes, but with a critical security note: always bind your Go application's debug endpoint (`/debug/pprof`) to `localhost` (e.g., `localhost:6060`), not `0.0.0.0`. This endpoint has no authentication and exposes sensitive internal memory layout. Go Runtime operates locally by communicating with this localhost endpoint.
