AI agents use explode_compound 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.
This tool decomposes a compound shape into individual objects, creating new objects in the FreeCAD document. It is a Write operation as it modifies the document by creating new shape objects. While the original compound may still exist, new objects are created as a side effect.
From the tool's definition Separate a compound into individual shape objects... created_objects: List of created object names
Documented attack patterns abuse exactly the kind of access explode_compound gives an agent:
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. This is the rule we recommend for explode_compound:
{
"version": "1",
"default": "deny",
"tools": {
"explode_compound": {
"limits": [
{
"counter": "explode_compound_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}explode_compound 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.

Separate a compound into individual shape objects. Args: object_name: Name of the compound object to explode. doc_name: Document containing the object. Uses active document if None. Returns: Dictionary with result: - success: Whether operation succeeded - created_objects: List of created object names. 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 explode_compound: 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.
explode_compound 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 explode_compound 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 explode_compound. 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.
explode_compound 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.
