clone_tree · Tiling Trees MCP Server MCP: Risk & Policy

WHAT IT DOES

What clone_tree does on Tiling Trees MCP Server

AI agents use clone_tree to create or update resources in Tiling Trees MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tiling Trees MCP Server environment.

WHY IT NEEDS A POLICY

Why clone_tree needs a policy

This tool creates new data (a cloned tree) without modifying or deleting existing data. It is reversible—the clone can be deleted independently of the original. While it modifies the overall system state by adding a new tree, it does not execute external code, cause financial impact, or irreversibly delete data. It fits squarely in the Write category as a creation/duplication operation.

From the tool's definition The tool 'clone_tree' creates a deep copy of a tree with new IDs. This is explicitly a creation action—copying an existing tree structure into a new independent tree—which is reversible and has no destructive consequences.

What does the clone_tree tool do? +

Create a deep copy of a tree with new IDs. Useful for exploring different split strategies for the same problem. It is categorised as a Write tool in the Tiling Trees MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on clone_tree? +

Register the Tiling Trees MCP Server MCP server in PolicyLayer and add a rule for clone_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 Tiling Trees MCP Server. Nothing to install.

What risk level is clone_tree? +

clone_tree is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit clone_tree? +

Yes. Add a rate_limit block to the clone_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.

How do I block clone_tree completely? +

Set action: deny in the PolicyLayer policy for clone_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.

What MCP server provides clone_tree? +

clone_tree is provided by the Tiling Trees MCP Server MCP server (k-chrispens/tiling-trees-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
