WHAT IT DOES

What createParametricObject does on Spline MCP Server

AI agents use createParametricObject 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.

RISK

Why createParametricObject is rated Medium

The 'create' verb combined with 'ParametricObject' suggests generating a new asset or design element in Spline, which is reversible (can be deleted/undone). This is a Write operation rather than Execute because it creates a discrete object rather than running arbitrary code.

From the tool's definition Tool name 'createParametricObject' indicates creation of a new object in the Spline 3D design environment.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs createParametricObject 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 createParametricObject, this is the rule to start with:

createParametricObject Rate-limited

createParametricObject 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.
