MOST DANGEROUS TOOLS

High Risk

The most dangerous Mcp Freecad tools

Execute · High emit_custom_event Emitting a custom event triggers an external operation whose effects depend on the arguments passed. Execute · Medium freecad_boolean_cut A boolean cut is a geometric operation that modifies 3D objects by computing the difference between two shapes. Execute · Medium subscribe_to_events Subscribing to events triggers an ongoing external operation that establishes a persistent listener/callback mechanism within FreeCAD. Write · Medium boolean_cut Boolean cut is a constructive modeling operation that creates a new object through subtraction, modifying the CAD design.

23 of Mcp Freecad's 34 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Mcp Freecad

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

Rate limit write operations

{
  "boolean_cut": {
    "limits": [
      {
        "counter": "boolean_cut_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "freecad_list_documents": {
    "limits": [
      {
        "counter": "freecad_list_documents_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

FAQ

Questions about Mcp Freecad

How do I prevent bulk modifications through Mcp Freecad? +

The Mcp Freecad server has 20 write tools including boolean_cut, boolean_intersection, boolean_union. 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 Mcp Freecad.

How many tools does the Mcp Freecad MCP server expose? +

34 tools across 2 categories: Read, Write. 11 are read-only. 23 can modify, create, or delete data.

How do I enforce a policy on Mcp Freecad? +

Register the Mcp Freecad 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 Mcp Freecad tool call.

Deterministic rules across all 34 Mcp Freecad tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
