enable_rule · NeuronSearchLab MCP: Risk & Policy

WHAT IT DOES

What enable_rule does on NeuronSearchLab

AI agents use enable_rule to create or update resources in NeuronSearchLab — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NeuronSearchLab environment.

WHY IT NEEDS A POLICY

Why enable_rule needs a policy

This tool modifies system configuration by re-enabling a previously disabled ranking rule. It is a Write operation because it creates or modifies state reversibly. Severity is medium because enabling a rule could alter recommendation rankings and user experience, but the change is not destructive and can be reversed.

From the tool's definition Tool name 'enable_rule' and description 'Enable a ranking rule that was previously disabled' indicates modification of configuration state. The action is reversible (can be disabled again) and affects system behavior rather than deleting data.

Verdict

enable_rule Rate-limited

enable_rule stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches NeuronSearchLab, so you can run agents against it safely.

FAQ

Questions about enable_rule

What does the enable_rule tool do? +

Enable a ranking rule that was previously disabled. It is categorised as a Write tool in the NeuronSearchLab MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on enable_rule? +

Register the NeuronSearchLab MCP server in PolicyLayer and add a rule for enable_rule: 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.

What risk level is enable_rule? +

enable_rule is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit enable_rule? +

Yes. Add a rate_limit block to the enable_rule 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.

How do I block enable_rule completely? +

Set action: deny in the PolicyLayer policy for enable_rule. 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.

What MCP server provides enable_rule? +

enable_rule 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.
