WHAT IT DOES

What vrc_decimate does on Blender Copilot MCP Server

AI agents invoke vrc_decimate 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.

RISK

Why vrc_decimate is rated High

Decimation in 3D modeling reduces polygon count, which is a mesh modification operation. Given the VRChat context and Blender environment, this likely modifies mesh geometry. With no description available, confidence is low. It could be Write (modifies mesh) or Execute (runs a processing operation).

From the tool's definition Tool name 'vrc_decimate' suggests a VRChat-related decimation operation (polygon reduction), but the description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

vrc_decimate Rate-limited

vrc_decimate 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 vrc_decimate call is checked against it from then on.

FAQ

Questions about vrc_decimate

What does the vrc_decimate tool do? +

vrc_decimate 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.

How do I enforce a policy on vrc_decimate? +

Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for vrc_decimate: 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.

What risk level is vrc_decimate? +

vrc_decimate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit vrc_decimate? +

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

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

vrc_decimate 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.
