## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_files",
    "arguments": {}

## Why list_files is rated Low

This tool retrieves metadata about uploaded files but does not create, modify, delete, or execute any operations. It is a passive data retrieval operation with no side effects, fitting the 'Read' category. Severity is low because listing files poses minimal risk even if misused by an agent—it exposes only metadata and file inventory without granting access to file contents or enabling destructive actions.

From the tool's own definition: "Tool name 'list_files' and description 'List all uploaded files with metadata' indicate a read-only operation that retrieves and queries data without modifying, deleting, or executing external operations."

## Use case

AI agents call list_files to retrieve information from Sap Btp Destination 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 Sap Btp Destination:

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