Roblox Studio MCP

\n

When to Load

\n

Load for Studio MCP work: scripts, scenes, assets, debugging, or playtesting. Skip for standalone code generation.

\n

Quick Reference

\n

Route by capability first. Two Studio MCP bridges exist: the official (built into Studio, closed-source) and chrrxs's (MIT). Route on tools/list (get_connected_instances/eval_*/multiplayer_* → chrrxs; list_roblox_studios + per-call studio_id → official) BEFORE bridge-specific bootstrap.

\n

Bootstrap before mutation

\n
    \n
  1. Identify the target via list_roblox_studios (official) or get_connected_instances (chrrxs).
    2. \n
  2. Pass the target's studio_id (official) or instance_id (chrrxs) on every tool call.
    3. \n
  3. get_studio_state and confirm Edit/Client/Server availability.
    4. \n
  4. Inspect the target tree and scripts before changing them.
    5. \n
\n

Execution contract

\n
discover → select Studio/context → inspect → mutate in bounded batches\n→ read back → start play → evaluate live → evidence → clean up\n
\n

Edit-time injection (multi_edit, Edit-context execute_luau) writes scripts; it never targets a running playtest. Live evaluation targets a running VM: start play, wait for the intended Client/Server VM, then evaluate there. A stopped VM is never a live-evaluation target. Pass datamodel_type only where the tool requires it; do not guess from a previous session.

\n

Capabilities

\n

Inspect (search_game_tree, inspect_instance, script_read, script_grep), edit/execute (multi_edit, execute_luau), assets (search_asset/insert_asset, generate_* with wait_job_finished, store_image/upload_image), play/evidence (start_stop_play, get_console_output, screen_capture, input simulation, subagent).
