WHAT IT DOES

What BrowserScroll does on DutyDeck

AI agents use BrowserScroll to create or update resources in DutyDeck, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DutyDeck environment.

RISK

Why BrowserScroll is rated Medium

An AI agent can call BrowserScroll faster than any human can review: one bad instruction and it creates or modifies resources in DutyDeck by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs BrowserScroll safely

PolicyLayer is an MCP gateway: it sits between your AI agents and DutyDeck, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For BrowserScroll, this is the rule to start with:

BrowserScroll Rate-limited

BrowserScroll 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.

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about BrowserScroll

What does the BrowserScroll tool do? +

Scroll the document or an optional CSS-selected scroll container using a fixed, data-only operation. This replaces page JavaScript for common window and internal-feed scrolling. Specify exactly one of deltaY or position. It is categorised as a Write tool in the DutyDeck MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on BrowserScroll? +

Register the DutyDeck MCP server in PolicyLayer and add a rule for BrowserScroll: 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 DutyDeck. Nothing to install.

What risk level is BrowserScroll? +

BrowserScroll is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit BrowserScroll? +

Yes. Add a rate_limit block to the BrowserScroll 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 BrowserScroll completely? +

Set action: deny in the PolicyLayer policy for BrowserScroll. 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 BrowserScroll? +

BrowserScroll is provided by the DutyDeck MCP server (taokoplay/DutyDeck). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
