AI agents call get_polyhaven_status to retrieve information from Blender without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about whether a feature is enabled. It performs a simple check and returns state information without modifying, executing, or deleting anything. The low severity reflects minimal blast radius if misused — an AI agent calling this repeatedly would only query status, not trigger actions or consume resources in a harmful way.
From the tool's definition Tool name is 'get_polyhaven_status' and description states it 'Check[s] if PolyHaven integration is enabled' — a purely informational query operation with no side effects.
Attacks that exploit this kind of access
Check if PolyHaven integration is enabled in Blender. It is categorised as a Read tool in the Blender MCP Server, which means it retrieves data without modifying state.
Register the Blender MCP server in PolicyLayer and add a rule for get_polyhaven_status: 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. Nothing to install.
get_polyhaven_status is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_polyhaven_status 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 get_polyhaven_status. 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.
get_polyhaven_status is provided by the Blender MCP server (silwings1986/blender-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
