What get_sketch_info does on FreeCAD Robust MCP Server
AI agents call get_sketch_info to retrieve information from FreeCAD Robust MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_sketch_info is rated Low
This tool retrieves or queries sketch information in FreeCAD without side effects. It follows the 'get_' naming convention which typically indicates read-only data retrieval. The empty description lowers confidence slightly, but the name and peer tools (add_*, activate_*) make the read-only intent clear. No data is created, modified, deleted, or executed. Low severity due to minimal blast radius if misused.
From the tool's definition Tool name 'get_sketch_info' implies information retrieval with no modification. The naming pattern (get_*) and context among sibling tools that add/modify sketch elements confirms a query operation.
Attacks that exploit this kind of access
The rule that runs get_sketch_info 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 get_sketch_info, this is the rule to start with:
get_sketch_info is read-only, so it stays allowed. 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 get_sketch_info call is checked against it from then on.
