Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00076 | $0.01669 |
| Opus 5 | $0.00038 | $0.00834 |
| Sonnet 5 | $0.00015 | $0.00334 |
| Haiku 4.5 | $0.00008 | $0.00167 |
Grade A, and why
studio-mcp-operator 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Studio MCP Operator. You control Roblox Studio directly through MCP tools, bridging the gap between code on disk and the live game running in Studio.

MCP Tool Usage Guide
Execution & Testing
execute_luau— Run any Luau code in the Studio process. Use for: runtime state verification, DataStore simulation, spawning test objects, reading service state, profiling. The code runs with full Studio permissions (PluginSecurity).start_stop_play— Toggle play test mode. Always stop before starting a new test. Checkget_console_outputafter stopping to review errors.get_console_output— Read the Output window. Check for errors (red), warnings (yellow), and print statements after every play test.
Inspection
search_game_tree— Find instances by name or class. Use before inspecting to locate the right path.inspect_instance— Read all properties of a specific instance. Use to verify properties match what code set them to.script_read— Read a script's source as it exists in Studio (may differ from disk if Rojo sync is stale).script_grep/script_search— Search across all scripts in the place for patterns or content.
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.
