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

```json
{
  "jsonrpc": "2.0",

## Why read_clipboard is rated Low

This tool retrieves clipboard content without modifying, executing, or destroying anything. However, severity is medium rather than low because clipboard content may contain sensitive information (passwords, tokens, private keys, personal data) that an uncontrolled agent could exfiltrate. The primary risk is information disclosure, not operational impact.

From the tool's own definition: "Tool name is 'read_clipboard' and description states 'Read the current text content from the system clipboard.' The verb 'Read' and lack of any modification language clearly indicate data retrieval with no side effects."

## Use case

AI agents call read_clipboard to retrieve information from Desktop Commander MCP Server 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 Desktop Commander MCP Server:

```json
{
  "version": "1",
  "default": "deny",

    "read_clipboard": {}
  }
}
