## What is PageSpeed Insights MCP?

PageSpeed Insights MCP is a **remote Model Context Protocol server** that provides AI assistants with website performance analysis capabilities. This performance optimization integration allows you to:

- Receive AI-powered optimization recommendations
- Check accessibility and SEO scores
- Identify resource optimization opportunities

## Installation

### Claude

1. Copy the MCP Server URL: `https://pagespeed-insights.insightfulmcp.com/`
2. Open [Claude Connectors Settings](https://claude.ai/settings/connectors)
3. Scroll to the bottom and click **Add custom connector**
4. Paste the URL and click **Add**
5. Click **Connect** and sign in to InsightfulPipe if asked. Claude then lists the connector as connected.

### ChatGPT

Custom MCP servers are added through ChatGPT's **Developer mode**. Availability depends on your ChatGPT plan, and workspace admins may need to allow it.

1. Turn on **Developer mode** in ChatGPT settings
2. Create a new app for a remote MCP server and paste the URL: `https://pagespeed-insights.insightfulmcp.com/`
3. Sign in to InsightfulPipe if asked. The connection finishes as soon as you are signed in.

See OpenAI's guide: [Developer mode and MCP apps in ChatGPT](https://help.openai.com/en/articles/12584461-developer-mode-and-mcp-apps-in-chatgpt)

### Claude Code

```bash
claude mcp add --transport http pagespeed https://pagespeed-insights.insightfulmcp.com/
```

### Cursor

Add the server to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (one project):

```json
{
  "mcpServers": {
    "pagespeed": {
      "url": "https://pagespeed-insights.insightfulmcp.com/"
    }
  }
}
```

When Cursor shows **Needs authentication**, click **Connect** and sign in to InsightfulPipe if asked.

## Available Actions

4 actions: 4 read, 0 write.

### Read Actions (4)

| Action | Description |
|--------|-------------|
| `accessibility-seo` | Accessibility and SEO category scores with failing audits |
| `analyze.full` | Full Lighthouse payload across all categories |
| `core-web-vitals` | Core Web Vitals snapshot (FCP, LCP, CLS, TTI, TBT, Speed Index, TTFB) |
| `resource-optimizations` | Resource-focused audits (render-blocking, unused JS/CSS, caching, images) |

## Control What Your AI Can Do

You decide what AI agents can do with each connected account:

- **Turn individual actions on or off** for every connected account, so agents only see the actions you allow.
- **Connect as Read-only or Read & Write.** A read-only connection can only enable read actions.
- **Destructive actions stay off by default.** Actions such as deletes are disabled until an admin enables them.
- **Team access per account.** Restricted team members only use the accounts they are granted, with the read actions enabled on them.
