Setup Guide

From zero to first MCP capture in 5 minutes

Connect your AI to your browser. Everything you need — install, authenticate, configure, capture.

Install the MCP extension

The MCP connector needs the E2LLM MCP extension — the relay-connected build that lets your AI read and act in your browser. Install it directly:

Download the MCP extension for Chrome (.zip) →

Unzip it, open chrome://extensions, turn on Developer mode, then click Load unpacked and select the folder. Full steps and other builds are on the extension page.

Not the same as the capture extension. The store listings (Chrome / Firefox) are the standalone capture-only extension — it does not connect to the MCP relay. For this setup, use the MCP build above.

Tip: After installation, you'll see the E2LLM icon in your browser toolbar. Click it to open the extension popup.

Create an account & sign in

Click the E2LLM extension icon and sign in with Google, Microsoft, GitHub, or email. Your account starts on the Free tier — all features included. See current limits.

The extension popup will show your account status and a green "Connected" indicator once authenticated.

Add MCP config to your AI tool

Copy the MCP configuration from your dashboard and paste it into your AI tool's settings.

Claude Code:

// Add to Claude Code MCP settings:

"e2llm": {
  "type": "url",
  "url": "https://mcp.e2llm.com/mcp"
}

OpenAI Codex:

# Run in terminal:
codex mcp add e2llm --url https://mcp.e2llm.com/mcp

Cursor / VS Code — and other MCP-compatible clients:

// Add to MCP settings:

"e2llm": {
  "url": "https://mcp.e2llm.com/mcp"
}

We test Claude Code and Codex on the command line, and Claude, ChatGPT, Grok, and Perplexity as connectors. Cursor, VS Code, Gemini, and other MCP-compatible clients use the same URL and should work — we just haven't individually tested each.

Your first capture

Open any website in your browser. Then ask your AI:

"Capture the current page and tell me what you see."

Your AI will call sifr_capture, receive a structured SiFR snapshot of the page, and describe what's on screen — elements, buttons, forms, content. All in 2-5K tokens instead of 200-400K raw HTML.

That's it. Your AI can now see and act in your browser. Try: "Click the search button", "Fill in the email field", "Scroll down and read the footer."

Troubleshooting

Extension shows "Disconnected": Refresh the page (F5), then try again. If still disconnected, close and reopen Chrome/Firefox.

"No response from content script": The page's content script may have been unloaded. Refresh the target page and retry.

AI tool can't connect: Make sure the extension is signed in with the same account. Check that the MCP config URL is exactly https://mcp.e2llm.com/mcp.

Known limitation: Some custom date pickers, rich text editors (TipTap/ProseMirror), and heavily dynamic widgets may require multiple capture-act cycles. Your AI will adapt automatically.
