Copy text to the system clipboard. Useful for copying MCP server URLs or config snippets.
AI agents invoke oc_copy_to_clipboard to trigger actions in OpenChrome. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Writing to the system clipboard is a browser/OS-level action with external side effects beyond simple data storage. It modifies shared system state (the clipboard) that other applications and users can read, and could be misused to silently overwrite clipboard contents with malicious payloads. This goes beyond a plain Write because it triggers an OS-level operation rather than modifying application data reversibly.

Documented attack patterns abuse exactly the kind of access oc_copy_to_clipboard gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenChrome, and nothing reaches the server without passing your rules. This is the rule we recommend for oc_copy_to_clipboard:
{
"version": "1",
"default": "deny",
"tools": {
"oc_copy_to_clipboard": {
"limits": [
{
"counter": "oc_copy_to_clipboard_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}oc_copy_to_clipboard stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Copy text to the system clipboard. Useful for copying MCP server URLs or config snippets. It is categorised as a Execute tool in the OpenChrome MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the OpenChrome MCP server in PolicyLayer and add a rule for oc_copy_to_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 OpenChrome. Nothing to install.
oc_copy_to_clipboard is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the oc_copy_to_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 oc_copy_to_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.
oc_copy_to_clipboard is provided by the OpenChrome MCP server (shaun0927/openchrome). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
