What tilemap_get_cell does on Godot Breakpoint
AI agents call tilemap_get_cell to retrieve information from Godot Breakpoint without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why tilemap_get_cell is rated Low
This tool retrieves tile data from a single cell in a tilemap layer. It performs a read-only query operation that returns the cell's properties (source_id, atlas_coords, alternative, empty flag) without creating, modifying, deleting, or executing any code. The low severity reflects minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'tilemap_get_cell' and description explicitly states 'Read one cell of a TileMapLayer' with no modifications or side effects.
Attacks that exploit this kind of access
The rule that runs tilemap_get_cell safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tilemap_get_cell, this is the rule to start with:
tilemap_get_cell is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot Breakpoint, apply this rule, and every tilemap_get_cell call is checked against it from then on.
Questions about tilemap_get_cell
Read one cell of a TileMapLayer. An empty cell reads back as source_id -1, atlas_coords [-1, -1], alternative 0 (empty = true). It is categorised as a Read tool in the Godot Breakpoint MCP Server, which means it retrieves data without modifying state.
Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for tilemap_get_cell: 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 Godot Breakpoint. Nothing to install.
tilemap_get_cell 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 tilemap_get_cell 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 tilemap_get_cell. 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.
tilemap_get_cell is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
