WHAT IT DOES

What search does on Npm

AI agents call search to retrieve information from Npm without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search is rated Low

This tool retrieves information from the npm registry without creating, modifying, deleting, or executing anything. It is a straightforward query operation analogous to a search function, which falls squarely into the Read category with low severity because misuse poses minimal risk (worst case: noisy or spam queries).

From the tool's definition Tool is described as 'Searches the npm registry for packages matching a query' — a lookup operation with no modifications, deletions, or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Npm, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search, this is the rule to start with:

search Allowed

search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Npm, apply this rule, and every search call is checked against it from then on.

FAQ

Questions about search

What does the search tool do? +

Searches the npm registry for packages matching a query. It is categorised as a Read tool in the Npm MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search? +

Register the Npm MCP server in PolicyLayer and add a rule for search: 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 Npm. Nothing to install.

What risk level is search? +

search is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search? +

Yes. Add a rate_limit block to the search 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 search completely? +

Set action: deny in the PolicyLayer policy for search. 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 search? +

search is provided by the Npm MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
