Pulse MCP

The Pulse MCP server allows AI agents to check web pages against Google's Core Web Vitals using field data from the Chrome UX Report and live Lighthouse lab runs. It supports retrieving metrics like LCP, INP, and CLS to determine if a page passes Google's ranking thresholds, helping developers debug performance issues and monitor site health.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http pulse-mcp-allthepossibles https://pulse.allthepossibles.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add pulse-mcp-allthepossibles --url https://pulse.allthepossibles.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable pulse-mcp-allthepossibles in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "pulse-mcp-allthepossibles": {
      "url": "https://pulse.allthepossibles.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "pulse-mcp-allthepossibles": {
      "type": "streamableHttp",
      "url": "https://pulse.allthepossibles.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start pulse-mcp-allthepossibles and inspect its tools.

      "type": "http",
      "url": "https://pulse.allthepossibles.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http pulse-mcp-allthepossibles https://pulse.allthepossibles.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
