List all ranking pipelines.
AI agents call list_pipelines 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.
The tool retrieves and enumerates existing ranking pipelines without creating, modifying, executing, or deleting them. This is a straightforward read operation with minimal blast radius—it exposes information about available pipelines but does not trigger their execution or alter system state. Severity is low because listing pipelines is informational and cannot cause harm even if misused by an AI agent.
From the tool's definition Tool name 'list_pipelines' and description 'List all ranking pipelines' indicate a retrieval operation with no modification or execution of pipelines themselves.
Attacks that exploit this kind of access
List all ranking pipelines. 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_pipelines: 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_pipelines 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_pipelines 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_pipelines. 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_pipelines 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.
