What create_glass does on Blender Copilot MCP Server
AI agents use create_glass 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.
Why create_glass is rated Medium
This tool creates or modifies material attributes on a Blender object. While it alters the 3D scene state, the change is reversible (materials can be changed or removed), so it falls under Write rather than Destructive. The severity is medium because misuse could degrade a complex scene's appearance or apply unwanted materials to many objects, but the effect is easily undone.
From the tool's definition Tool name 'create_glass' and description 'Apply a glass/transparent material to an object' indicate the tool modifies object material properties in Blender, which is a reversible change to scene data.
Attacks that exploit this kind of access
The rule that runs create_glass 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_glass, this is the rule to start with:
create_glass 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_glass call is checked against it from then on.
Questions about create_glass
Apply a glass/transparent material to an object. It is categorised as a Write tool in the Blender Copilot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for create_glass: 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 Blender Copilot MCP Server. Nothing to install.
create_glass is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_glass 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.
Set action: deny in the PolicyLayer policy for create_glass. 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.
create_glass is provided by the Blender Copilot MCP Server MCP server (dwgx/blender-copilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
