The MCP-native browser agent
One config block gives Claude, Cursor, VS Code, or Windsurf a real browser. One tool, a session that stays signed in, and unblocking built in. Running on the browser infrastructure Browserless has kept in production since 2017.
Why browser agents stall
Most browser tools weren't built for agents. Some load dozens of tool definitions into your context window before the first click. Some put a second LLM in the loop and bill you for it on top of the browser. Some hand you infrastructure and leave the agent part to you. Browserless Agent is built differently.
How Browserless Agent works
The agent runs a tight loop on every task: snapshot, plan, act.
Step 1
Snapshot
Capture every interactive element on the page as a compact list with stable selectors. No raw DOM, no screenshots.
Step 2
Plan
The model reads the snapshot and decides the next move: navigate, click, type, or wait for the page to change.
Step 3
Act
Send a method, or batch several into one call. The session stays open and the browser stays warm.
The agent re-snapshots whenever the page changes, so it always acts on what is actually there, then closes the session when the task is done.
How Browserless Agent compares
One tool, a persistent managed session, command batching, and built-in unblocking. No other browser agent combines all four.

Why engineering teams choose Browserless Agent
What you can build with Browserless Agent
Internal automation, live data extraction, personal agents: here's what teams run on Browserless Agent.
Automate multi-step business workflows
AI engineers, ops teams, anyone replacing brittle RPA pipelines
Your agent can log into a DigitalOcean account and pull a structured list of running droplets. It can reconcile invoices from QuickBooks against Stripe payouts, or fill out a vendor onboarding form for every customer in a CSV. Login state and page state survive the whole session, so multi-step flows behind authentication actually finish.
Extract structured data from any page
Data engineers, research teams, AI pipelines that need reliable extraction
Scrape a full catalogue with prices sorted. Pull a ticker's market data on a schedule. Build a product catalogue from a competitor's site. Snapshots use stable selectors that hold up across page changes, and BrowserQL underneath handles stealth, CAPTCHA solving, and proxy routing.
Power personal agents people actually trust
Founders building agent products, developers using Claude Code or Cursor for personal tasks
Consumer sites like Google Flights and Amazon are where agents fail most visibly, and it's usually bot detection, not the model, that kills the task. Browserless Agent gets through, at a speed your users will wait for. And with liveURL, you can watch the browser work or take over mid-session instead of babysitting a black box.
Get set up in under a minute
Add the block below to your Claude Desktop, Cursor, VS Code, or Windsurf config. It points at the hosted server, so there's nothing to install. If your client supports OAuth, skip the token and sign in with your Browserless account when prompted.

User: Pull every Pynchon book from Buscalibre with prices,
sorted cheapest to most expensive.
Agent: [calls browserless_agent]
snapshot: returns the element list for the search results page
batch: extract title and price per listing, follow pagination
snapshot: confirms the final page, verifies completeness
Agent: Done. 14 books found, sorted by price.Your agent doesn't have to handle this
The hardest parts of browser automation, the ones that break pipelines at 2 AM, are handled at the infrastructure layer. Browserless Agent inherits all of it.
