AI agents use fuse_all 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 creates a new geometry object by combining existing shapes into a union solid. It is a constructive/write operation that produces a new object in the FreeCAD document. It does not delete the source objects (they remain), so it is not Destructive. It does not execute arbitrary code or commands, making Write the most appropriate category.
From the tool's definition Fuse (union) multiple shapes into a single solid... fuses all specified objects at once
Documented attack patterns abuse exactly the kind of access fuse_all 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 fuse_all:
{
"version": "1",
"default": "deny",
"tools": {
"fuse_all": {
"limits": [
{
"counter": "fuse_all_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}fuse_all 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.

Fuse (union) multiple shapes into a single solid. Unlike boolean_operation which works on two objects at a time, this fuses all specified objects at once. Args: object_names: List of object names to fuse. result_name: Name for result object. Auto-generated if None. doc_name: Document containing the objects. Uses active document if None. Returns: Dictionary with result object information: - name: Result object name - label: Result object label - type_id: Result object type. 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 fuse_all: 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.
fuse_all 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 fuse_all 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 fuse_all. 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.
fuse_all 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.
