AI agents call list_pages to retrieve information from Nesift without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays metadata about previously indexed pages. It performs a passive query operation with no ability to modify, delete, or execute anything. The blast radius of misuse is minimal—an agent could enumerate indexed content but cannot alter state or trigger external actions. Classification as Read is appropriate.
From the tool's definition Tool name 'list_pages' and description 'Show indexed URLs with title, chunk count, and triage summary' indicate a retrieval/enumeration operation with no side effects.
Attacks that exploit this kind of access
Show indexed URLs with title, chunk count, and triage summary. It is categorised as a Read tool in the Nesift MCP Server, which means it retrieves data without modifying state.
Register the Nesift MCP server in PolicyLayer and add a rule for list_pages: 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 Nesift. Nothing to install.
list_pages 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_pages 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_pages. 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_pages is provided by the Nesift MCP server (scottgl9/nesift). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
