WHAT IT DOES

What add_rigid_body does on Blender Copilot MCP Server

AI agents use add_rigid_body 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 add_rigid_body is rated Medium

This tool adds a rigid body physics component to a Blender object, which is a reversible modification (the physics can be removed). It falls under Write as it modifies object properties without executing code or causing irreversible destruction. Misuse could alter scene physics unexpectedly but is recoverable.

From the tool's definition 'Add rigid body physics to an object. Types: ACTIVE (affected by gravity)' — creates/modifies physics properties on an object

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_rigid_body Rate-limited

add_rigid_body 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 add_rigid_body call is checked against it from then on.

FAQ

Questions about add_rigid_body

What does the add_rigid_body tool do? +

Add rigid body physics to an object. Types: ACTIVE (affected by gravity),. 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 add_rigid_body? +

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

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

Can I rate-limit add_rigid_body? +

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

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

add_rigid_body 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.
