WHAT IT DOES

What io_export_stl does on Blender Copilot MCP Server

AI agents use io_export_stl 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 io_export_stl is rated Medium

This tool creates and writes 3D model data to a file in STL format. It does not execute arbitrary code, delete data irreversibly, move money, or retrieve data without side effects. The export operation is reversible (the file can be deleted or overwritten), making it a Write operation.

From the tool's definition Tool name 'io_export_stl' and description 'Export to STL format (3D printing)' indicate file creation/writing. STL is a standard 3D model file format.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

io_export_stl Rate-limited

io_export_stl 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 io_export_stl call is checked against it from then on.

Questions about io_export_stl

What does the io_export_stl tool do? +

Export to STL format (3D printing). 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 io_export_stl? +

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

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

Can I rate-limit io_export_stl? +

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

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