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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "onedrive_read_file",
    "arguments": {
      "path": "<path>"
    }
  }
}
```

## Why onedrive_read_file is rated Low

This is a Read operation—it retrieves file contents without side effects. Severity is medium rather than low because it accesses both OneDrive and local filesystem, which could expose sensitive data (email attachments, financial documents, credentials) if an AI agent is misled into reading unintended files. The mention of 'banking .TXT padrones' suggests access to potentially sensitive financial records.

From the tool's own definition: "Tool name is 'onedrive_read_file' and description states it 'Reads a text file from OneDrive or the local filesystem' with no mention of modification, deletion, or execution. The action is retrieval only."

Risk signals: Accepts file system path (path)

## Use case

AI agents call onedrive_read_file to retrieve information from Local 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 Local:

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