godot-mcp: Instructions file for Claude Code

CLAUDE.md

godot-mcp CLAUDE.md is an instructions file for Claude Code from jamesdowzard/godot-mcp. It costs 502 tokens per session, scanned A, original, MIT.

A set of Claude Code instructions for developing a Godot 4 MCP server fork with Android export validation. Godot is a game engine, and Android export validation checks that Android build settings are present and valid.

In plain words
What is it for?
Use it when working on this Godot MCP server, especially its Android build checks or AI tooling.
Why use it?
It explains the fork's purpose, development commands, project layout, and rules so changes follow the repository's conventions.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is jamesdowzard/godot-mcp's own configuration. It tells Claude Code how to work on godot-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 godot-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

godot-mcp CLAUDE.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 2mo 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.

godot-mcp

MCP server for Godot 4 with Android export validator support. Fork of Coding-Solo/godot-mcp at commit 1209744 (MIT licence); maintained independently by @jamesdowzard. Fork relationship is severed at the git level; attribution preserved per MIT.

Published npm: @jamesdowzard/godot-mcp.

Why the fork exists

Upstream does not cover Android export validation. James's Godot work (piano-xr, vr-player, others) needs automated checks that Android export presets are present and valid before a CI/local build. This fork adds that validator and other AI-friendly tooling.

Do not submit changes here upstream unless you are sure they belong there — the fork's direction is AI tooling + Android pipeline, which may diverge from upstream's scope.

Run / dev

bun install             # or npm i
bun run build
bun run dev             # local stdio server for Claude Code

Register in ~/.claude.json MCP servers block (stdio transport) — see README.md for the exact snippet.

Layout

Top-level directories, as harness-docs-drift reads them against git ls-files. Only depth-0 rows are parsed — keep this flat.

└── src/
Path Purpose
src/ TypeScript MCP server — tool handlers, Godot CLI wrapper
build/ compiled JS (committed for quick npm install)
scripts/ dev helpers

House rules

  • Feature branches only. No direct commits to main.
  • Keep Android export validator and other added tools cleanly separated from upstream modules so a future upstream rebase stays tractable.
  • MIT notices must stay intact — do not remove the upstream attribution header in README.md.
  • Reference: reference_godot_mcp_fork.md in auto-memory.
  • Apps using it: piano-xr, vr-player, unity-quest-base-adjacent work.
  • Claude Code dossier: dossiers/claude-stack/ covers the MCP server inventory.

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.
