What vrc_physbone_config does on Blender Copilot MCP Server
AI agents use vrc_physbone_config 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 vrc_physbone_config is rated Medium
Configuring physics bone parameters is a reversible modification operation (Write category). It doesn't delete data (not Destructive), doesn't execute arbitrary code (not Execute), and doesn't involve financial transactions (not Financial). Severity is medium because misconfiguration could affect avatar functionality in VRChat, but changes are reversible.
From the tool's definition Tool name 'vrc_physbone_config' suggests configuration of VRChat physics bone properties. VRChat physbones are parameters that control avatar physics behavior in the VRChat platform.
Attacks that exploit this kind of access
The rule that runs vrc_physbone_config 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_physbone_config, this is the rule to start with:
vrc_physbone_config 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 vrc_physbone_config call is checked against it from then on.
Questions about vrc_physbone_config
vrc_physbone_config is a write tool on the Blender Copilot MCP Server MCP server. 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 vrc_physbone_config: 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.
vrc_physbone_config 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 vrc_physbone_config 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 vrc_physbone_config. 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.
vrc_physbone_config 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.
