Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Roblox Studio MCP
When to Load
Load when working with Roblox Studio via its built-in MCP server — script editing, scene building, playtesting, or debugging. Provides direct access to the data model, Luau execution, asset generation, and player simulation tools. Skip if generating standalone scripts without a Studio connection.
Quick Reference
Tools by category:
- Scripts:
script_read,multi_edit,script_search,script_grep - Data model:
search_game_tree,inspect_instance,explore_subagent - Execute:
execute_luau(stateless — re-acquire refs every call) - Playtest:
start_stop_play,console_output,screen_capture,playtest_subagent - Input sim:
character_navigation,keyboard_input,mouse_input - Assets:
generate_mesh,generate_material,generate_procedural_model,insert_from_creator_store - Session:
list_roblox_studios,set_active_studio
Critical reliability patterns:
execute_luauis stateless — re-acquire all references every call- Silent failures — verify after creation (
FindFirstChildcheck) - Script truncation — chunk writes for >300 lines; read back to verify
- Batching — 10-20 parts/call safe, one script/call, verify after batches
- Ground truth — never guess coords/sizes; always READ current state
Core workflows:
- Script dev:
search_game_tree→script_read→multi_edit→script_read(verify) →start_stop_play+console_output - Build geometry:
search_game_tree→execute_luau(create) →execute_luau(verify count) →screen_capture - Debug:
start_stop_play→console_output→inspect_instance→multi_edit→start_stop_play - Playtest:
start_stop_play→character_navigation→keyboard_input/mouse_input→console_output+screen_capture
MCP mode detection:
- Official (built-in): full tool set including
execute_luau,multi_edit,search_game_tree - Community (Chrrxs):
execute_luau,get_file_tree,grep_scripts,create_build - No MCP: pure code generation — provide copy-paste-ready scripts
