What addHanaElement does on Spline MCP Server
AI agents use addHanaElement to create or update resources in Spline MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Spline MCP Server environment.
Why addHanaElement is rated Medium
The 'add' prefix and contextual similarity to sibling tools that create/modify 3D scene components (cameras, lights, materials, UI objects) indicates this tool creates or adds new elements to a Spline design. This is a Write operation—reversible creation/modification of scene data. Severity is medium because misuse could create unwanted scene elements, but changes are undoable in a design tool.
From the tool's definition Tool name 'addHanaElement' with sibling tools like 'addCamera', 'addDirectionalLight', 'addMaterialLayer', and 'addObjectToUILayout' all prefixed with 'add', indicating creation of scene elements. Description is empty, limiting certainty.
Attacks that exploit this kind of access
The rule that runs addHanaElement safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Spline MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For addHanaElement, this is the rule to start with:
addHanaElement stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Spline MCP Server, apply this rule, and every addHanaElement call is checked against it from then on.
