AI agents call get_latest_selection to retrieve information from Yocoolab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves the most recent element selection from the Chrome extension and returns metadata about that element. It is purely informational with no capability to modify, delete, execute code, or trigger financial transactions. The verb 'Returns' combined with read-only data extraction (selectors, styles, attributes, context) clearly places this in the Read category.
From the tool's definition Tool description explicitly states it 'Returns' data about a recent selection without any modification or side effects. Returns 'element selector, tag, text content, classes, attributes, computed styles, and page context' — all observational data retrieval.
Attacks that exploit this kind of access
Returns the most recent element selection from the Chrome extension. Includes element selector, tag, text content, classes, attributes, computed styles, and page context. It is categorised as a Read tool in the Yocoolab MCP Server, which means it retrieves data without modifying state.
Register the Yocoolab MCP server in PolicyLayer and add a rule for get_latest_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 Yocoolab. Nothing to install.
get_latest_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_latest_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_latest_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_latest_selection is provided by the Yocoolab MCP server (yocoolab/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
