count

What count does on Npm

AI agents call count 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.

Why count is rated Low

The tool performs a search operation (ripgrep pattern matching) and returns aggregated results. It has no side effects, does not execute arbitrary code, does not modify or delete data, and does not involve financial transactions. This is a straightforward Read classification with low severity because pattern counting poses minimal risk even if misused by an AI agent.

From the tool's definition Tool description states it 'Counts pattern matches per file using ripgrep. Returns per-file match counts and totals.' This is a read-only operation that searches and counts text patterns without modifying, executing code, or deleting data.

The rule that runs count 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 count, this is the rule to start with:

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