What input.scroll does on Glasswarp
AI agents invoke input.scroll to trigger actions in Glasswarp. 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
x | integer | Yes | Native X to hover before scrolling |
y | integer | Yes | Native Y to hover before scrolling |
delta | integer | Yes | Vertical wheel delta (negative = toward bottom of page) |
session_id | string | Yes | Active session id |
Parameters from the server's own tool schema.
Why input.scroll is rated High
Triggers real mouse-wheel input on a live Windows PC, causing side effects.
From the tool's definition Move cursor, apply vertical mouse-wheel delta, scroll under point
Attacks that exploit this kind of access
The rule that runs input.scroll safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Glasswarp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For input.scroll, this is the rule to start with:
input.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 Glasswarp, apply this rule, and every input.scroll call is checked against it from then on.
Questions about input.scroll
Move the cursor to native (x,y) then apply a vertical mouse-wheel delta. Side effect: scroll on whatever is under that point. Negative delta scrolls toward the bottom of the page. Prefer input.send_actions when scroll is part of a multi-step sequence. Re-observe after scrolling lists/pages before clicking targets. It is categorised as a Execute tool in the Glasswarp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
input.scroll accepts 4 parameters: x, y, delta, session_id. Required: x, y, delta, session_id. The full parameter table on this page comes from the server's own tool schema.
Register the Glasswarp MCP server in PolicyLayer and add a rule for input.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 Glasswarp. Nothing to install.
input.scroll 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 input.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.
Set action: deny in the PolicyLayer policy for input.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.
input.scroll is provided by the Glasswarp MCP server (https://mcp.glasswarp.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
