AI agents call get_clipboard to retrieve information from MCP 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 contents without modifying system state or triggering external operations. It is a read-only query of clipboard data. While clipboard data could theoretically be sensitive (depending on what a user has copied), the tool itself performs no destructive, write, execute, or financial operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for get_clipboard:
{
"version": "1",
"default": "deny",
"tools": {
"get_clipboard": {}
}
}get_clipboard is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the MCP Windows MCP server in PolicyLayer and add a rule for get_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 MCP Windows. Nothing to install.
get_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 get_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 get_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.
get_clipboard is provided by the MCP Windows MCP server (secretiveshell/mcp-windows). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Windows, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
