AGENTS.md

gke-mcp AGENTS.md is an instructions file for Codex, OpenCode from GoogleCloudPlatform/gke-mcp. It costs 837 tokens per session, scanned A, original, Apache-2.0.

A repository-specific instruction guide for GoogleCloudPlatform/gke-mcp, a Go server with a web interface. It explains the project layout, development commands, generated files, and checks to run before submission.

In plain words
What is it for?
Building and testing the Go server, installing and building the web interface, running lint and formatting tasks, checking generated UI bundles, and running presubmit checks.
Why use it?
It reduces mistakes caused by using the wrong build, test, formatting, or UI-generation command in an unfamiliar codebase.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Gemini CLI.

This is GoogleCloudPlatform/gke-mcp's own configuration. It tells Codex and OpenCode how to work on gke-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything gke-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gke-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This repository contains the GKE MCP server and Gemini CLI extension. The main server is written in Go. Web UI assets live under ui/ and are built into checked-in single-file HTML bundles under ui/dist/apps/.

Repository Layout

  • cmd/, pkg/: Go source for the MCP server, tools, config, and agents.
  • ui/: Vite/React TypeScript apps and shared UI code.
  • ui/apps/*/index.html: source app HTML entrypoints.
  • ui/dist/apps/*/index.html: generated, checked-in UI bundles embedded by Go.
  • dev/tasks/: local maintenance tasks that may update files.
  • dev/ci/presubmits/: CI-equivalent verification scripts.

Development Commands

  • Build everything: make build
  • Build Go only: go build -v ./...
  • Run Go tests: go test -v ./...
  • Run Go vet: go vet ./...
  • Install UI dependencies: npm --prefix ui install
  • Build UI bundles: npm --prefix ui run build
  • Run UI tests: npm --prefix ui run test
  • Run UI lint: npm --prefix ui run lint
  • Format all supported files: ./dev/tasks/format.sh
  • Format Markdown files after editing: npx prettier --write <files>
  • Run local presubmit: ./dev/tasks/presubmit.sh or make presubmit

Run the smallest relevant check for the files you changed. For broad changes, prefer make presubmit when feasible.

Generated Files

The files under ui/dist/apps/ are generated but checked in because Go embeds them. Do not edit them by hand. Change source files under ui/apps/, ui/shared/, or UI build configuration, then regenerate with:

npm --prefix ui run build

To verify generated UI bundles are current, run:

./dev/ci/presubmits/verify-ui.sh

If verify-ui.sh reports changes after an intentional UI update, include the updated ui/dist/apps/*/index.html files in the same change.

Go Guidelines

  • Keep Go code formatted with gofmt.
  • If dependencies change, run go mod tidy or ./dev/tasks/gomod.sh.
  • Add or update focused tests near changed behavior.
  • Prefer existing package patterns in pkg/tools, pkg/config, and pkg/agents before adding new abstractions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
