What create_sketch does on FreeCAD Robust MCP Server
AI agents use create_sketch 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.
Why create_sketch is rated Medium
The tool creates new data structures (sketches) in FreeCAD's document model. While the description is uninformative, the naming convention and server context indicate this is a create/write operation rather than destructive (sketches can be deleted) or execute (it doesn't run arbitrary code). Confidence is moderate (0.75) due to the empty description; higher confidence would require explicit documentation.
From the tool's definition Tool named 'create_sketch' with no description provided. Based on sibling tools (add_sketch_arc, add_sketch_bspline, add_sketch_circle, etc.) and the server's purpose of '3D modeling, macro development,' this tool creates new sketch objects in FreeCAD, which…
Attacks that exploit this kind of access
The rule that runs create_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 create_sketch, this is the rule to start with:
create_sketch 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 create_sketch call is checked against it from then on.
Questions about create_sketch
create_sketch 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.
Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for create_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.
create_sketch is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_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 create_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.
create_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.
