WHAT IT DOES

What add_sketch_point does on FreeCAD Robust MCP Server

AI agents use add_sketch_point 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 add_sketch_point is rated Medium

This tool creates a new sketch point, which is a reversible modification to a FreeCAD sketch object. It does not execute arbitrary code, delete data, or move money. The lack of tool description lowers confidence slightly, but the naming pattern and sibling context strongly indicate a Write classification. Severity is medium because misuse could corrupt a design file, but changes are typically undoable in FreeCAD.

From the tool's definition Tool name 'add_sketch_point' indicates it adds a geometric element to a sketch, and the sibling tools (add_sketch_arc, add_sketch_line, add_sketch_rectangle, etc.) are all write operations that create/modify sketch geometry.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_sketch_point Rate-limited

add_sketch_point 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 add_sketch_point call is checked against it from then on.

Can I rate-limit add_sketch_point? +

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

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

add_sketch_point 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.
