Roblox studio mcp

Roblox Studio MCP

When to Load

Load when working with Roblox Studio through its MCP server: inspecting or editing scripts, building maps and props, generating or inserting assets, debugging, or playtesting. Skip for standalone code generation with no Studio connection.

Quick Reference

Bootstrap before mutation

1. list_roblox_studios and identify the target.
2. set_active_studio with the returned ID when selection matters.
3. get_studio_state and confirm Edit/Client/Server availability.
4. Inspect the target tree and scripts before changing them.

Use the actual exposed schema. Pass datamodel_type only where the tool requires it: Edit for edit-time changes, Client or Server for runtime operations. Do not guess from a previous session.

Capabilities

• Inspect: search_game_tree, inspect_instance, script_search, script_read, script_grep
• Edit/execute: multi_edit, execute_luau
• Assets: search and insert existing assets; generate_mesh, generate_material, generate_procedural_model, wait_job_finished, store_image, upload_image
• Play/evidence: start_stop_play, get_console_output, screen_capture, character_navigation, user_keyboard_input, user_mouse_input, subagent

The docs use names such as search_asset and insert_asset; other bridges may expose aliases such as search_creator_store and insert_from_creator_store. Route by capability, then inspect the live schema.

Execution contract

discover → select Studio/context → inspect → mutate in bounded batches
→ read back → playtest when needed → inspect console/visual evidence
→ clean up or report the exact fallback

Reliability rules

• execute_luau is stateless. Re-acquire references every call.
• Read before write and read back after every script, asset, or geometry mutation.
• Generate or insert assets only after choosing between reuse, procedural generation, mesh/material generation, and native fallback.
• Treat generation as asynchronous when a generation ID is returned; call wait_job_finished with that generationId before dependent edits.
• Keep large scripts in multi_edit chunks, not one oversized execution payload.
• If MCP is absent or a capability is unavailable, provide complete offline Luau and state what was not verified.
