WHAT IT DOES

What curve_to_mesh does on Blender Copilot MCP Server

AI agents use curve_to_mesh 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 curve_to_mesh is rated Medium

This tool creates or modifies geometry in the Blender scene by converting curves to meshes. While it transforms existing data, the conversion is reversible (the original curve object typically remains or can be restored via undo), making it a Write operation rather than Destructive.

From the tool's definition Tool name 'curve_to_mesh' and description 'Convert a curve to mesh geometry' indicate a transformation operation that modifies the scene by converting one geometric type to another.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

curve_to_mesh Rate-limited

curve_to_mesh 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.
