MOST DANGEROUS TOOLS

Critical Risk

The most dangerous FreeCAD Robust MCP Server tools

Destructive · High delete_macro The tool name 'delete_macro' clearly indicates deletion of macro files or objects in FreeCAD. Destructive · High delete_object Deletion of objects in CAD models is irreversible and represents data loss. Destructive · Medium delete_sketch_constraint Deletion of sketch constraints in FreeCAD is an irreversible operation that modifies the underlying model geometry and structure. Destructive · High delete_sketch_geometry The 'delete_' prefix indicates this tool performs irreversible data destruction.

129 of FreeCAD Robust MCP Server's 152 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control FreeCAD Robust MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and FreeCAD Robust MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "close_document": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "add_external_geometry": {
    "limits": [
      {
        "counter": "add_external_geometry_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "draft_list_fonts": {
    "limits": [
      {
        "counter": "draft_list_fonts_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

FAQ

Questions about FreeCAD Robust MCP Server

Can an AI agent delete data through the FreeCAD Robust MCP Server MCP server? +

Yes. The FreeCAD Robust MCP Server server exposes 6 destructive tools including close_document, delete_macro, delete_object. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through FreeCAD Robust MCP Server? +

The FreeCAD Robust MCP Server server has 98 write tools including add_external_geometry, add_sketch_arc, add_sketch_bspline. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach FreeCAD Robust MCP Server.

How many tools does the FreeCAD Robust MCP Server MCP server expose? +

152 tools across 4 categories: Destructive, Execute, Read, Write. 23 are read-only. 129 can modify, create, or delete data.

How do I enforce a policy on FreeCAD Robust MCP Server? +

Register the FreeCAD Robust MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every FreeCAD Robust MCP Server tool call.

Deterministic rules across all 152 FreeCAD Robust MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
