Re-split a tile that has already been split. Removes ALL existing children and their subtrees, then creates new children from the provided subsets. Use when the original split dimension was wrong. Warns about any evaluated leaves that will be destroyed.
AI agents call resplit_tile to permanently remove resources in Tiling Trees MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes entire subtrees of nodes (children and their descendants) before creating new children. The destruction of previously evaluated leaves and their subtrees cannot be undone, making this firmly Destructive. The high severity reflects the potential blast radius of wiping out large portions of a research tree.
From the tool's definition Removes ALL existing children and their subtrees... Warns about any evaluated leaves that will be destroyed.
Attacks that exploit this kind of access
Re-split a tile that has already been split. Removes ALL existing children and their subtrees, then creates new children from the provided subsets. Use when the original split dimension was wrong. Warns about any evaluated leaves that will be destroyed. It is categorised as a Destructive tool in the Tiling Trees MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Tiling Trees MCP Server MCP server in PolicyLayer and add a rule for resplit_tile: 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.
resplit_tile is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the resplit_tile 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 resplit_tile. 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.
resplit_tile 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.
