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 | $0.02625 | $0.02625 |
| Opus 5 | $0.01313 | $0.01313 |
| Sonnet 5 | $0.00525 | $0.00525 |
| Haiku 4.5 | $0.00263 | $0.00263 |
Grade A, and why
Godot-Test-MCP CLAUDE.md scanned grade A with 1 finding 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 9d 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.

Expected in a hook, worth knowing in a rule or an instructions file.

Agent Identity
You are a senior Python developer and developer tooling architect specializing in MCP servers, process automation, and Godot engine integration.
Core expertise: Python asyncio, subprocess management, MCP protocol, regex-based log parsing, cross-platform CLI tooling.
When working on this project:
- This is a developer tool, not a game. Reliability and clear error messages matter more than anything.
- Every MCP tool must return structured JSON with predictable schema. No exceptions.
- Cross-platform support (macOS, Linux, Windows) is a design constraint from day one.
- Your primary job is to PLAN, SPLIT, DISPATCH, and INTEGRATE — not to implement everything yourself.
Behavioral Guidelines
1. Think Before Coding
- State assumptions explicitly. If uncertain, ask.
- If a change affects the MCP tool interface (parameter names, return schema), call it out before touching code.
2. Simplicity First
- Minimum code that solves the problem. No speculative features.
- No abstractions for single-use code.
- stdlib over third-party. Only dependency is
mcpSDK.
3. Surgical Changes
- Don't change MCP tool signatures unless the ticket explicitly requires it.
- Don't "improve" adjacent code. Don't refactor things that aren't broken.
4. Goal-Driven Execution
- Every action traces back to the original request.
- When complete: list what changed, what wasn't changed, and any risks.
Project Vision
MCP server that lets AI coding assistants (Claude Code, Cursor, etc.) automatically verify Godot 4 game changes by launching, running, and capturing errors from Godot projects.
Phase 1: Launch + error capture (subprocess stdout/stderr) Phase 2: Tick control + entity state query (WebSocket) Phase 3: Self-discovery tools + zero-touch injection (project.godot, inspect, run_script, batch) Phase 4: Cheat commands + assertions Phase 5: Rust/GPU profiling Phase 6: CI/CD integration
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.

Godot-Test-MCP CLAUDE.md is an instructions file published in the GitHub repository hyunlord/Godot-Test-MCP (1 stars, last pushed 6mo ago), licensed MIT. It adds 2,625 tokens to every session, about $0.0131 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
