WHAT IT DOES

What create_curve does on Blender Copilot MCP Server

AI agents use create_curve to create or update resources in Blender Copilot MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Blender Copilot MCP Server environment.

RISK

Why create_curve is rated Medium

This tool creates new 3D data (a curve object) in the Blender scene, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or have irreversible effects. The severity is medium because misuse could clutter a scene or create unwanted geometry, but the effects are easily undone in Blender (undo/delete).

From the tool's definition Tool name 'create_curve' and description 'Create a curve from a list of control points' indicates creation of new geometry/data in Blender scene.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_curve safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Blender Copilot MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_curve, this is the rule to start with:

create_curve Rate-limited

create_curve 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 Blender Copilot MCP Server, apply this rule, and every create_curve call is checked against it from then on.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Blender Copilot MCP Server. Nothing to install.

What risk level is create_curve? +

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

Can I rate-limit create_curve? +

Yes. Add a rate_limit block to the create_curve 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 create_curve completely? +

Set action: deny in the PolicyLayer policy for create_curve. 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 create_curve? +
