What set_clipboard does on Mcp Control Plane
AI agents use set_clipboard to create or update resources in Mcp Control Plane, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Control Plane environment.
Why set_clipboard is rated Medium
Setting clipboard text creates or modifies data (clipboard contents) in a reversible manner. While it affects system state, it is not destructive (can be overwritten), not code execution, and not financial.
From the tool's definition Tool name is 'set_clipboard' and description states 'Set clipboard text.' This directly modifies the clipboard contents, which is a reversible write operation on system state.
Attacks that exploit this kind of access
The rule that runs set_clipboard safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_clipboard, this is the rule to start with:
set_clipboard stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every set_clipboard call is checked against it from then on.
Questions about set_clipboard
Set clipboard text. It is categorised as a Write tool in the Mcp Control Plane MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for set_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 Control Plane. Nothing to install.
set_clipboard is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_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 set_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.
set_clipboard is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
