AI agents call puppeteer_get_title to retrieve information from Claude TypeScript MCP Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (the page title) from a currently-loaded webpage. It is a read-only operation with no side effects, no data modification, and no capability to execute arbitrary code or perform financial transactions. The blast radius of misuse is minimal—an AI agent can only learn the page title, which is already visible in the browser UI.
From the tool's definition Tool name 'puppeteer_get_title' and description 'Get the page title' indicate a retrieval operation that queries the DOM for the page title attribute without modifying, deleting, or executing external operations.

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_get_title:
{
"version": "1",
"default": "deny",
"tools": {
"puppeteer_get_title": {}
}
} puppeteer_get_title is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the page title. It is categorised as a Read tool in the Claude TypeScript MCP Servers MCP Server, which means it retrieves data without modifying state.
Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for puppeteer_get_title: 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 Claude TypeScript MCP Servers. Nothing to install.
puppeteer_get_title is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the puppeteer_get_title 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 puppeteer_get_title. 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.
puppeteer_get_title 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.
Start from Claude TypeScript MCP Servers, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
