What constrain_perpendicular does on FreeCAD Robust MCP Server
AI agents use constrain_perpendicular 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 constrain_perpendicular is rated Medium
With no description, classification is based on naming conventions and sibling tools. 'constrain_perpendicular' most likely adds a geometric constraint between two sketch elements, which is a reversible write/modification operation. Confidence is lowered due to empty description.
From the tool's definition Tool name 'constrain_perpendicular' with empty description. Based on sibling tools like 'add_sketch_constraint', this likely adds a perpendicular constraint to sketch geometry in FreeCAD.
Attacks that exploit this kind of access
The rule that runs constrain_perpendicular 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 constrain_perpendicular, this is the rule to start with:
constrain_perpendicular 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 constrain_perpendicular call is checked against it from then on.
Questions about constrain_perpendicular
constrain_perpendicular 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 constrain_perpendicular: 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.
constrain_perpendicular 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 constrain_perpendicular 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 constrain_perpendicular. 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.
constrain_perpendicular 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.
