Unblocked is a free desktop app that runs a real browser on your computer. Connect it to Cursor in one click and the agent can read live documentation, changelogs and pages that normally block automated tools.
Point Cursor's agent at a changelog or an API reference and it reads the live page instead of recalling an old version.
Framework docs and dashboards that render client-side come back complete, not as an empty HTML shell.
Cursor has a proper install link, so connecting is a click in Unblocked and a confirm in Cursor.
Download the app and open it. It appears in your menu bar or tray.
Unblocked opens Cursor through its official install link.
Cursor asks you to approve the new tool. Accept, and the agent can browse.
Drop this into ~/.cursor/mcp.json — it's exactly what the one-click install writes.
{
"mcpServers": {
"unblocked": {
"url": "http://127.0.0.1:8484/mcp"
}
}
}Paste this into the agent once you've connected.
Use Unblocked to fetch https://www.google.com/search?q=unblocking+api and list the top 10 results.In your global ~/.cursor/mcp.json, so it works in every project. You can see it in Cursor under Settings → MCP.
That means your system has no handler for Cursor's cursor:// links — usually because Cursor isn't installed, or has never been opened. Unblocked then shows you the snippet to paste instead.
No. Unblocked is a separate app; Cursor only talks to it when the agent actually needs a page. Rendering happens in a browser dedicated to the local API, so your requests never queue behind anything else.
Cursor can't reach the app, which almost always means Unblocked isn't running. Open it from your menu bar; Cursor picks the tools back up on its own.
One app, all your assistants. Connect as many as you like.
Free, open to everyone, and set up in about a minute. No account, no API key, no credit card.
