Vision Roblox MCP
Automates Roblox Studio tasks via MCP by combining multiple backends for scene editing, script management, asset insertion, and playtesting with safety features like undo recordings and task leasing.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
vision_statusGet live health and capability status for the Vision API, Studio plugin, Roblox native MCP, Rojo, and task queue.
vision_search_instancesSearch the latest Studio snapshot by name, path, class, service, tag, attribute, or common property.
vision_inspect_instanceInspect one instance from Vision's latest Studio snapshot, including properties, attributes, tags, and children.
vision_read_scriptRead a synced Roblox LuaSourceContainer by full Studio path.
vision_list_tasksList queued, leased, successful, failed, or cancelled Studio tasks and their result history.
vision_queue_taskQueue one validated modular Studio task. Destructive, code, and asset operations are blocked unless enabled in Vision settings.
vision_queue_batchQueue an ordered group of validated tasks that Studio applies as one undo recording.
vision_create_build_planCreate an approval-ready spatial plan from the latest Studio snapshot without applying it.
vision_accept_build_planAccept a reviewed Vision plan and queue its grouped Studio tasks.
vision_retry_taskReset a failed or cancelled Studio task to queued state.
vision_cancel_taskCancel a queued or leased Studio task before it is applied.
vision_native_mcp_callCall an available tool from Roblox Studio's built-in MCP. Mutating tools require approved=true and the corresponding Vision safety setting.
vision_rojoInspect, start, stop, build, or generate a sourcemap for a Rojo project inside the Vision workspace.

ROBLOX_CREATOR_IDROBLOX_CREATOR_TYPEROBLOX_OPEN_CLOUD_API_KEYROJO_PATHVISION_API_PORTVISION_API_URLVISION_PROVIDER_API_KEYVISION_PROVIDER_BASE_URLVISION_PROVIDER_MODELAll four hints declared on every tool
13/13 tools missing one or more hints — vision_status (missing: destructiveHint, idempotentHint); vision_search_instances (missing: destructiveHint, idempotentHint); vision_inspect_instance (missing: destructiveHint, idempotentHint), +10 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
openWorldHint matches behaviour
13 tools claim openWorldHint=false but make outbound HTTP — vision_status → dynamic (line 239); vision_search_instances → dynamic (line 239); vision_inspect_instance → dynamic (line 239)
Either flip openWorldHint to true (acknowledging external reach) or refactor the handler to avoid outbound HTTP. If the only network calls are to a known fixed endpoint that you consider part of the tool itself, document that and keep openWorldHint=false; otherwise true is honest.
Tool inputs are validated
12/13 tool handlers declare input schemas (92%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/13 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/13 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 2 high severity in production deps — vite@6.0.7 (high), vite@6.0.7 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
