Remote MCPNothing to install · open-source CLI

Connect your agents to anything.

Even the ones without an API. One link for Claude, ChatGPT, Cursor or any MCP app; your agent uses the site’s own API, or a cloud browser when there isn’t one.

01 · The page

Websites are built for eyes.

Buttons, layout, pixels. Agents today drive them in a browser: launch Chromium, click, wait, read eight thousand tokens of HTML — then do it again tomorrow.

02 · The network

Underneath, every page already calls an API.

Unbrowse watches the site's own first-party requests — the JSON the page fetches for itself — and keeps the ones that answer the task.

03 · The compile

Compiled into one tool.

Typed inputs, a verified answer, replayed over plain HTTP in 50–200 ms. No browser window. Your agent calls it like any other tool.

04 · The registry

Every site. One MCP.

3,292 tools already compiled from the top 10,000 websites, re-verified in the background. Anything missing is learned the first time your agent asks.

1
MCP is how AI apps plug in tools.
An open standard. Claude, ChatGPT, Cursor, VS Code and most agent frameworks support it.
2
Remote means nothing to install.
Unbrowse runs in the cloud. You add a link, not software. Remove it any time.
3
One server, every website.
No connector per app. Name any site and Unbrowse finds a way in, then saves it as a tool your agent reuses.

## After you connect

Skip the page. Call the route.

Speed

Skip the rendering engine

A browser is expensive when the page only hides a request. Unbrowse calls the site’s own first-party API over plain HTTP, and keeps a cloud browser for the sites that still need one.

Tokens

Fewer tokens

A route returns structured data, so the model reads the answer instead of a whole rendered page.

Discovery

Learns what’s missing

No route yet? Your agent does the task once in a cloud browser. Unbrowse watches the site’s own traffic and compiles it into a tool it can reuse.

Accounts

Your accounts. Your choice.

Choose which accounts to connect and whether saved logins can be reused. Passwords stay in your vault and are typed into the site’s own form; your agent only sees a masked hint. How account access works

The registry

3,292 tools. Already compiled.

3,292 tools in the public registry, from a crawl of the top 10,000 websites: 337 site searches and flows, and page reading for 2,955 sites. Anything missing is learned on first use.

## The problem

Three ways to see the same website.

A person sees a page. A browser agent reads it, pass after pass. Unbrowse calls what the page was calling.

Illustrative replay. Measured speedups are in the paper below.

Internal APIs are all you need.

Why the first-party routes already powering modern websites are the machine-native interface for agents, and how a shared route graph turns repeated browser rediscovery into collective memory.

## Before you connect

Explicit, not magic.

Do I need to know how to code?

No. In Claude or ChatGPT you paste one link into the connector settings and sign in. Developer tools like Cursor and Claude Code take one click or one command.

What is MCP?

Model Context Protocol, the open standard AI apps use to plug in tools. A remote MCP server like Unbrowse lives at a web address, so you add a link instead of installing anything.

Does this work with every website?

Support varies by website and task. Some sites support searching, some support reading pages, and others need a connected account. Check a site’s available actions first. If a task is blocked or unsupported, it may not be possible to complete it.

Can I use my own accounts?

Yes, where the website supports sign-in through Unbrowse. Save a login in your private vault and choose whether your assistant can reuse it. You may still need to complete a sign-in or verification step yourself.

Will my assistant see my passwords?

Saved passwords stay in your Unbrowse vault and are filled into the website’s sign-in form. They are not sent to the AI model. Information your assistant retrieves from an account can appear in your conversation.

Can I stop access later?

Yes. Disconnect Unbrowse in your assistant’s settings. You can also manage saved logins and their reuse permissions in your Unbrowse account.

Is Unbrowse free?

Unbrowse is free during beta, with 500 verified calls a month. A task may use several calls. Failed, blocked and refused calls do not count. See pricing for the current allowance and details.
