What is godot-mcp AGENTS.md?

A project instruction document for godot-mcp, a tool that lets an AI agent control the Godot 4 game engine through a connection. It describes important files, dependencies and conventions.

Use it when developing or maintaining godot-mcp, especially when working on its server, Godot bridge, game-building pipeline, fleet features, imports, playtesting or exports.

It gives coding agents the project context needed to change the right parts without guessing how the repository is organised.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00917	$0.00917
Opus 5.5	$0.00367	$0.00367
Sonnet 5.5	$0.00183	$0.00183
Haiku 4.5	$0.00092	$0.00092

Security

Grade A, and why

godot-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.

All tools register via src/godot_mcp/tools/__init__.py → register_all(mcp). Each module has a register(mcp) function. New modules MUST be added to the register_all imports and calls.

Key Dependencies

worldlabs-mcp (port 10865): Called via MCPBridgeClient from godot_mcp.mcp_bridge for Marble world generation
Godot 4.4 (port 9080): TCP bridge using mcp_bridge.gd autoload
Butler (BUTLER_API_KEY): itch.io CLI for shipping

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.
