Get an object from a document. You can use this tool to get the properties of an object to see what you can check or edit. Args: doc_name: The name of the document to get the object from. obj_name: The name of the object to get. Returns: The object and a screenshot of the object.
AI agents call get_object to retrieve information from Freecad mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data about an object in FreeCAD (its properties and visual representation) without creating, modifying, deleting, or executing any operations. It is a pure read operation with no side effects.
From the tool's definition Tool description states 'Get an object from a document' and 'get the properties of an object', with no mention of modification or side effects. The return value is 'The object and a screenshot of the object', indicating retrieval only.
Documented attack patterns abuse exactly the kind of access get_object gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Freecad mcp, and nothing reaches the server without passing your rules. This is the rule we recommend for get_object:
{
"version": "1",
"default": "deny",
"tools": {
"get_object": {}
}
}get_object is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get an object from a document. You can use this tool to get the properties of an object to see what you can check or edit. Args: doc_name: The name of the document to get the object from. obj_name: The name of the object to get. Returns: The object and a screenshot of the object. It is categorised as a Read tool in the Freecad mcp MCP Server, which means it retrieves data without modifying state.
Register the Freecad MCP server in PolicyLayer and add a rule for get_object: 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 mcp. Nothing to install.
get_object is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_object 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 get_object. 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.
get_object is provided by the Freecad MCP server (neka-nat/freecad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Freecad mcp, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
