# list_drive_files

List the Google Drive files & folders Hermoso can reach — the ones it created, plus any the user handed over with the Google file picker in the app (the drive.file scope exposes nothing else, never their entire Drive). This is how you find the id of a file the user picked. Filter by query (name contains …), folderId (contents of a folder), or onlyFolders:true. Paginate with pageToken. Read-only.

## Why list_drive_files is rated Low

Even though list_drive_files only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Hermoso:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_drive_files": {}
  }
}
```
