AI agents call read_grid_map to retrieve information from Godot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This tool retrieves information about GridMap nodes and their properties (cell size, mesh library references) without modifying, executing, or deleting anything. It is a pure data query with no blast radius if misused by an AI agent.
From the tool's definition Tool name is 'read_grid_map' and description states 'List GridMap nodes' — a retrieval/query operation with no side effects. The verb 'read' and 'list' are canonical Read operations.
Attacks that exploit this kind of access
List GridMap nodes with cell size and mesh library references. It is categorised as a Read tool in the Godot MCP Server, which means it retrieves data without modifying state.
read_grid_map accepts 1 parameter: scene_path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for read_grid_map: 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. Nothing to install.
read_grid_map 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 read_grid_map 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 read_grid_map. 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.
read_grid_map is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
read_grid_map is one line of Godot's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
