What tilemap_set_cell does on Godot
AI agents use tilemap_set_cell to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
Why tilemap_set_cell is rated Medium
This tool modifies tilemap state within a Godot project (Write category). It is not destructive since tilemap changes are reversible through undo or re-editing. Severity is medium because incorrect tilemap modifications could corrupt level layouts or require manual repair, but the scope is limited to a single game asset.
From the tool's definition Tool name 'tilemap_set_cell' indicates modification of tilemap data within a Godot project. The 'set' verb combined with 'cell' parameters suggests writing/updating cell values in a tilemap structure.
Attacks that exploit this kind of access
The rule that runs tilemap_set_cell safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tilemap_set_cell, this is the rule to start with:
tilemap_set_cell 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every tilemap_set_cell call is checked against it from then on.
