What sculpt_brush_stroke does on Blender Copilot MCP Server
AI agents invoke sculpt_brush_stroke to trigger actions in Blender Copilot MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why sculpt_brush_stroke is rated High
Based on the name, this tool likely executes a sculpt brush stroke operation in Blender, which modifies 3D mesh geometry. This is an Execute-level action (triggering an external operation in Blender). Since the description is empty, confidence is reduced. It could also be Write since it modifies mesh data reversibly, but brush strokes in sculpting are typically executed as operations rather than simple data writes.
From the tool's definition Tool name 'sculpt_brush_stroke' on a Blender MCP server; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs sculpt_brush_stroke 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 sculpt_brush_stroke, this is the rule to start with:
sculpt_brush_stroke stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 sculpt_brush_stroke call is checked against it from then on.
Questions about sculpt_brush_stroke
sculpt_brush_stroke is a execute tool on the Blender Copilot MCP Server MCP server. It is categorised as a Execute tool in the Blender Copilot MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for sculpt_brush_stroke: 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.
sculpt_brush_stroke is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the sculpt_brush_stroke 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 sculpt_brush_stroke. 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.
sculpt_brush_stroke 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.
