AI agents call read_clipboard to retrieve information from Computer Use Windows without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves clipboard data, which is a read operation with no side effects. However, severity is elevated to medium rather than low because clipboard contents may contain sensitive information (passwords, API keys, personal data) that an AI agent could exfiltrate. The risk depends on what a user has copied, but the access to such potentially sensitive data warrants medium severity classification.

Register the Computer Use Windows MCP server in PolicyLayer and add a rule for read_clipboard: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Computer Use Windows. Nothing to install.
read_clipboard is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the read_clipboard rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for read_clipboard. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
read_clipboard is provided by the Computer Use Windows MCP server (wimi321/windows-computer-use-skill). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
read_clipboard is one line of Computer Use Windows's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
