WHAT IT DOES

What export_step does on FreeCAD Robust MCP Server

AI agents use export_step to create or update resources in FreeCAD Robust MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FreeCAD Robust MCP Server environment.

RISK

Why export_step is rated Medium

Export operations write/serialize data to external files. While export itself does not modify the original model (reversible via re-import), it creates new persistent files and could expose sensitive design data. This fits Write category rather than Read because it generates and commits data to storage, distinct from merely querying.

From the tool's definition Tool name is 'export_step' which exports 3D model data to STEP format; sibling tools are all 3D modeling operations (sketches, workbenches, constraints), indicating this server manages CAD design files.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs export_step safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FreeCAD Robust MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For export_step, this is the rule to start with:

export_step Rate-limited

export_step 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 FreeCAD Robust MCP Server, apply this rule, and every export_step call is checked against it from then on.

FAQ

Questions about export_step

What does the export_step tool do? +

export_step is a write tool on the FreeCAD Robust MCP Server MCP server. It is categorised as a Write tool in the FreeCAD Robust 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 export_step? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for export_step: 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 FreeCAD Robust MCP Server. Nothing to install.

What risk level is export_step? +

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

Can I rate-limit export_step? +

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

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

export_step is provided by the FreeCAD Robust MCP Server MCP server (spkane/freecad-addon-robust-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
