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

```json

## Why write_clipboard is rated Medium

This tool modifies system clipboard state reversibly. While it could be leveraged to inject malicious content (URLs, scripts, commands) that a user might subsequently paste, the operation itself is non-destructive and reversible. Severity is medium rather than high because clipboard injection requires subsequent user action to cause harm, and the impact is limited to the clipboard buffer.

From the tool's own definition: "Tool name 'write_clipboard' and description 'Write text to the system clipboard' explicitly indicate creation/modification of clipboard data."

## Use case

AI agents use write_clipboard to create or update resources in Desktop Commander MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Desktop Commander MCP Server environment.
