WHAT IT DOES

What scroll does on Mcp Control Plane

AI agents invoke scroll to trigger actions in Mcp Control Plane. 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.

RISK

Why scroll is rated High

Scrolling is an external UI operation that affects the state of an active window. It's not purely reading data, nor writing/destructive/financial — it executes a browser/desktop interaction. Severity is low since scrolling has minimal blast radius and is easily reversible by scrolling back.

From the tool's definition 'Scroll the active window. Positive values scroll up, negative values scroll down.' — triggers a UI interaction/browser action on the active window

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs scroll 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 scroll, this is the rule to start with:

scroll Rate-limited

scroll 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every scroll call is checked against it from then on.

FAQ

Questions about scroll

What does the scroll tool do? +

Scroll the active window. Positive values scroll up, negative values scroll down. It is categorised as a Execute tool in the Mcp Control Plane MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on scroll? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for scroll: 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.

What risk level is scroll? +

scroll is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit scroll? +

Yes. Add a rate_limit block to the scroll 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.

How do I block scroll completely? +

Set action: deny in the PolicyLayer policy for scroll. 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.

What MCP server provides scroll? +

scroll 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.
