WHAT IT DOES

What create_hole does on FreeCAD Robust MCP Server

AI agents use create_hole 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 create_hole is rated Medium

The tool creates new geometry in a 3D model, which is reversible (holes can be removed/modified in CAD software). This is a Write operation rather than Execute because it modifies the model state directly rather than running arbitrary code. Severity is medium because misuse could corrupt or make an intentional design unusable, but changes can be undone with undo/version control.

From the tool's definition Tool name 'create_hole' in FreeCAD context indicates creation/modification of 3D model geometry. Empty description limits precision, but naming pattern aligns with sibling tools (add_sketch_arc, add_sketch_circle) that perform constructive operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_hole 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_hole, this is the rule to start with:

create_hole Rate-limited

create_hole 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_hole call is checked against it from then on.

FAQ

Questions about create_hole

What does the create_hole tool do? +

create_hole 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 create_hole? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer and add a rule for create_hole: 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 create_hole? +

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

Can I rate-limit create_hole? +

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

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

create_hole 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.
