What rhino_export_dxf does on Rhino
AI agents use rhino_export_dxf to create or update resources in Rhino, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rhino environment.
Why rhino_export_dxf is rated Medium
The tool exports geometry to a DXF file format, which is a reversible write operation—it creates new external data (the DXF file) but does not destructively alter or delete the original model. An AI agent misusing this could export sensitive geometry or create unintended files, but the impact is limited to file creation rather than data destruction or execution of arbitrary operations.
From the tool's definition Tool name 'rhino_export_dxf' and description 'Export to DXF' indicate creation/writing of file data in DXF format. The export operation creates a new file artifact without deleting or modifying the source geometry in Rhino.
Attacks that exploit this kind of access
The rule that runs rhino_export_dxf safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Rhino, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rhino_export_dxf, this is the rule to start with:
rhino_export_dxf 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 Rhino, apply this rule, and every rhino_export_dxf call is checked against it from then on.
Questions about rhino_export_dxf
Export to DXF (bridge required). It is categorised as a Write tool in the Rhino MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Rhino MCP server in PolicyLayer and add a rule for rhino_export_dxf: 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 Rhino. Nothing to install.
rhino_export_dxf 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 rhino_export_dxf 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 rhino_export_dxf. 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.
rhino_export_dxf is provided by the Rhino MCP server (easehee/rhino-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
