count

What count does on Cargo

AI agents call count to retrieve information from Cargo 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 read-only operation: searching for pattern matches and returning counts. It does not create, modify, delete, execute code, or move money. Ripgrep is a search utility, and counting matches is a non-destructive query. The blast radius of misuse is minimal—worst case an agent could search for sensitive patterns, but this is lower risk than operations that change state.

From the tool's definition Tool description states it 'Counts pattern matches per file using ripgrep' and 'Returns per-file match counts and totals.' This is a search/query operation that retrieves information without modifying data.

The rule that runs count safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Cargo, 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": {}
  }
}
