WHAT IT DOES

What puppeteer_clear_input does on Claude TypeScript MCP Servers

AI agents invoke puppeteer_clear_input to trigger actions in Claude TypeScript MCP Servers. 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.

THE RISK

Why puppeteer_clear_input needs a policy

This tool performs a browser automation action (clearing an input field) via Puppeteer. It's not a simple read and modifies the state of a running browser session. Clearing an input field is a reversible browser interaction, making Execute the appropriate category rather than Write (which typically implies persistent data modification). Misuse could disrupt active browser sessions or automated workflows.

From the tool's definition Clear an input field — uses Puppeteer to interact with a browser/DOM element, triggering an external browser action

POLICY

How to control puppeteer_clear_input

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude TypeScript MCP Servers, and nothing reaches the server without passing your rules. This is the rule we recommend for puppeteer_clear_input:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "puppeteer_clear_input": {
      "limits": [
        {
          "counter": "puppeteer_clear_input_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

puppeteer_clear_input 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.

Create a free account and register Claude TypeScript MCP Servers — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I block puppeteer_clear_input completely? +

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

puppeteer_clear_input is provided by the Claude TypeScript MCP Servers MCP server (ukkz/claude-ts-mcps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
