WHAT IT DOES

What origin_set does on Blender Copilot MCP Server

AI agents use origin_set 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 origin_set is rated Medium

This tool modifies object metadata (origin/pivot point) reversibly within a Blender scene. It is a Write operation because it changes object state but does not delete data or execute arbitrary code. The severity is medium because incorrect origin placement could disrupt modeling workflows, rigging, or animation, but the change is fully reversible via undo or re-execution.

From the tool's definition Tool name 'origin_set' and description 'Set the origin point of an object' indicate modification of object properties in Blender.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

origin_set Rate-limited

origin_set 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 origin_set call is checked against it from then on.

FAQ

Questions about origin_set

What does the origin_set tool do? +

Set the origin point of 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.

How do I enforce a policy on origin_set? +

Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for origin_set: 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 origin_set? +

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

Can I rate-limit origin_set? +

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

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

origin_set 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.
