Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to allthepossibles.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Pulse checks a page's real Core Web Vitals (LCP, INP, CLS) from Chrome UX Report field data plus a live Lighthouse lab run.

What you can do: Check a page's Core Web Vitals for a given URL, combining Chrome UX Report field data from real users over a 28-day window with a live Lighthouse lab run.
Get good, needs-improvement or poor ratings for LCP, INP and CLS against Google's published thresholds, plus whether the page passes the ranking-signal bar.
When to use it: Useful when you want an assistant to assess page performance or Core Web Vitals for a URL without opening PageSpeed Insights or running Lighthouse yourself, for example while auditing a site or checking whether a page meets Google's thresholds.
Requirements: A remote MCP endpoint reached over streamable HTTP; no package, environment variables or headers are declared. The manifest declares no authentication.

Before you install

The tool sends the URL you supply to a third-party service, which queries Chrome UX Report and Lighthouse data for it. The registry description mentions daily checks on a Pro tier, so paid plans may exist; confirm pricing and any account requirements before relying on it.

Installation

In SourceWeft

Open Pulse in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.allthepossibles%2Fpulse/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Check Core Web Vitals

Check a page's real Core Web Vitals: Google's Chrome UX Report field data (real users, 28-day window) plus a live Lighthouse lab run. Returns good/needs-improvement/poor ratings for LCP, INP, and CLS per Google's own published thresholds, and whether the page passes the actual ranking-signal bar. Call this before telling someone a page performs well. Pass a Pro API key as a Bearer token for 500 checks/minute; see /docs for monitoring multiple URLs with daily regression alerts.

72% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
