Explain why a specific item was (or would be) ranked at a particular position for a user.
AI agents call explain_ranking 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 ranking logic/reasoning for an item—a read-only informational operation with no side effects. It neither modifies data, executes code, deletes records, nor moves money. The blast radius of misuse is minimal; an agent could only spam requests or retrieve explanations it shouldn't access, both low-impact scenarios in a recommendation context.
From the tool's definition Tool name 'explain_ranking' and description 'Explain why a specific item was (or would be) ranked at a particular position for a user' indicate a query/retrieval operation that returns explanatory data without modifying state or triggering external operations.
Attacks that exploit this kind of access
Explain why a specific item was (or would be) ranked at a particular position for a user. 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 explain_ranking: 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.
explain_ranking 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 explain_ranking 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 explain_ranking. 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.
explain_ranking 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.
explain_ranking is one line of NeuronSearchLab's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
