List the top items by served count or by matching event activity such as watch or click over a time window. For generic
AI agents call top_items to retrieve information from NeuronSearchLab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents aggregated data about items and user interactions. It performs a read-only query against existing metrics and event data. There is no capability to modify, delete, execute commands, or commit financial transactions. The blast radius of misuse is limited to potential information disclosure about popular items or user behavior patterns, which constitutes low risk.
From the tool's definition Tool description states it 'List[s] the top items' - a retrieval operation with no indication of modification, deletion, or execution of arbitrary code. It filters/queries items based on metrics (served count, event activity) within a time window.
Attacks that exploit this kind of access
List the top items by served count or by matching event activity such as watch or click over a time window. For generic. It is categorised as a Read tool in the NeuronSearchLab MCP Server, which means it retrieves data without modifying state.
Register the NeuronSearchLab MCP server in PolicyLayer and add a rule for top_items: 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 NeuronSearchLab. Nothing to install.
top_items 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 top_items 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 top_items. 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.
top_items is provided by the NeuronSearchLab MCP server (neuronsearchlab/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
