Get the object tree structure for a Penpot object
AI agents call get_object_tree to retrieve information from Penpot MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves structural information about design objects in Penpot. It performs a read-only query operation with no side effects, no code execution, no data modification, and no irreversible actions. The blast radius of misuse is minimal since it only exposes existing design structure information.
From the tool's definition Tool name is 'get_object_tree' and description states 'Get the object tree structure for a Penpot object' — this is a retrieval operation that queries hierarchical data without modification.
Documented attack patterns abuse exactly the kind of access get_object_tree gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Penpot MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_object_tree:
{
"version": "1",
"default": "deny",
"tools": {
"get_object_tree": {}
}
}get_object_tree is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the object tree structure for a Penpot object. It is categorised as a Read tool in the Penpot MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Penpot MCP Server MCP server in PolicyLayer and add a rule for get_object_tree: 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 Penpot MCP Server. Nothing to install.
get_object_tree 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_tree 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_tree. 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_tree is provided by the Penpot MCP Server MCP server (montevive/penpot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Penpot MCP Server, 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.
