What revolution_sketch does on FreeCAD Robust MCP Server
AI agents invoke revolution_sketch to trigger actions in FreeCAD Robust MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why revolution_sketch is rated High
Based on FreeCAD domain knowledge, 'revolution_sketch' likely performs a revolve/lathe operation on a sketch to generate a 3D body — this is a modeling execution operation. However, the description is empty, lowering confidence. It fits Execute (triggers a 3D modeling operation) rather than Write since it runs a CAD operation with geometry-dependent effects.
From the tool's definition Tool name 'revolution_sketch' with empty description. In FreeCAD context, this likely revolves/rotates a sketch profile around an axis to create a 3D solid (a standard modeling operation).
Attacks that exploit this kind of access
The rule that runs revolution_sketch 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 revolution_sketch, this is the rule to start with:
revolution_sketch stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 revolution_sketch call is checked against it from then on.
Questions about revolution_sketch
revolution_sketch is a execute tool on the FreeCAD Robust MCP Server MCP server. It is categorised as a Execute tool in the FreeCAD Robust MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for revolution_sketch: 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.
revolution_sketch is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the revolution_sketch 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 revolution_sketch. 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.
revolution_sketch 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.
