List ranking rules, optionally filtered by context.
AI agents call list_rules 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 or queries ranking rules metadata. It has no side effects, cannot modify data, and presents no risk of destructive action or code execution. The filtering parameter is purely for search refinement, not data mutation. This is a straightforward Read operation with minimal risk.
From the tool's definition Tool name 'list_rules' and description 'List ranking rules, optionally filtered by context' indicate a retrieval operation with no modification capability.
Attacks that exploit this kind of access
List ranking rules, optionally filtered by context. 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 list_rules: 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.
list_rules 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 list_rules 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 list_rules. 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.
list_rules 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.
