WHAT IT DOES

What createState does on Spline MCP Server

AI agents use createState 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 createState is rated Medium

State creation in a 3D design tool is a reversible modification operation—new states can be deleted or modified without destroying the underlying scene. This is Write-level risk, not Execute, because it creates data structures rather than running arbitrary code. Severity is medium because misuse could create unwanted states, but effects are reversible and limited to the design project scope.

From the tool's definition Tool name is 'createState' with empty description; sibling tools show this is a Spline 3D design tool context where 'add' and 'apply' operations modify design state.

RECOMMENDED RULE

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

createState Rate-limited

createState 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Spline MCP Server, apply this rule, and every createState call is checked against it from then on.

FAQ

Questions about createState

What does the createState tool do? +

createState is a write tool on the Spline MCP Server MCP server. It is categorised as a Write tool in the Spline MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on createState? +

Register the Spline MCP Server MCP server in PolicyLayer and add a rule for createState: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Spline MCP Server. Nothing to install.

What risk level is createState? +

createState is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit createState? +

Yes. Add a rate_limit block to the createState rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block createState completely? +

Set action: deny in the PolicyLayer policy for createState. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides createState? +

createState is provided by the Spline MCP Server MCP server (aydinfer/spline-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
