Check if PrusaSlicer is available and report version.
AI agents call slicer_status to retrieve information from FreeCAD MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the availability and version of PrusaSlicer, a pure information retrieval operation with no side effects. It does not execute slicing, create files, modify configurations, or trigger external processes beyond checking status. Misuse poses minimal risk as it only returns diagnostic information.
From the tool's definition Tool performs a status check ('Check if PrusaSlicer is available and report version') which retrieves information about the external slicer application without modifying any state or triggering operations.
Attacks that exploit this kind of access
Check if PrusaSlicer is available and report version. It is categorised as a Read tool in the FreeCAD MCP MCP Server, which means it retrieves data without modifying state.
Register the FreeCAD MCP server in PolicyLayer and add a rule for slicer_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 FreeCAD MCP. Nothing to install.
slicer_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 slicer_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 slicer_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.
slicer_status is provided by the FreeCAD MCP server (sandraschi/freecad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
