What read_clipboard does on CoWork OS
AI agents call read_clipboard to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why read_clipboard is rated Low
This tool retrieves data from the clipboard without altering it, creating side effects, or executing commands. It is a pure read operation with minimal risk—clipboard data may contain sensitive information, but the tool itself performs no destructive, write, or execution operations. Severity is low because misuse would only expose existing data rather than cause system-wide damage or financial harm.
From the tool's definition Tool name 'read_clipboard' and description 'Read the current contents of the system clipboard' explicitly indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
The rule that runs read_clipboard safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_clipboard, this is the rule to start with:
read_clipboard is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every read_clipboard call is checked against it from then on.

Register the CoWork OS 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 CoWork OS. 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 CoWork OS MCP server (CoWork-OS/CoWork-OS). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
