Gets the name of the currently selected GameObject in the Editor.
AI agents call get_selection to retrieve information from MCP For Unity without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves information about the current editor state (which GameObject is selected) without modifying, creating, deleting, or executing any operations. It is a read-only query of the editor's internal state, posing minimal security risk.
From the tool's definition Tool name is 'get_selection' and description states it 'Gets the name of the currently selected GameObject in the Editor' — a pure retrieval operation with no side effects.
Attacks that exploit this kind of access
Gets the name of the currently selected GameObject in the Editor. It is categorised as a Read tool in the MCP For Unity MCP Server, which means it retrieves data without modifying state.
Register the MCP For Unity MCP server in PolicyLayer and add a rule for get_selection: 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 MCP For Unity. Nothing to install.
get_selection 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 get_selection 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 get_selection. 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.
get_selection is provided by the MCP For Unity MCP server (yunuscan/mcpforunity). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
