Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 4 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Today, automating web tasks feels like managing half a dozen different interfaces.
Right now, if your agent needs to interact with any modern website—one that requires a login or runs JavaScript—you have to deal with brittle code. You're constantly writing workarounds for how the site loads content, managing session state manually, and hoping you don't forget to clean up resources when the task finishes.
With this MCP, your agent just gets a real browser context in the cloud. It handles the complexity of modern web interactions so you can focus on what matters: the data. You get reliable, isolated sessions ready for action.
Browserbase gives you full control over the session lifecycle.
You no longer have to guess if a previous task left resources running or if the state is corrupted. You can systematically `list_browser_sessions` to audit all activity, use `get_browser_session` to diagnose failures by checking historical page visits, and then guarantee cleanup with `stop_browser_session`.
This MCP means your agent’s interactions are predictable, auditable, and self-contained. It's a complete system for running browser tasks.
What your AI can actually do with this
You need more than just static data; you need a browser. This MCP connects your AI agent directly to live web infrastructure. It lets your agent launch controlled, temporary Chromium sessions in the cloud, giving it the full capabilities of Playwright or Puppeteer. The process is simple: your agent can initiate a session, interact with any modern website—clicking buttons, filling complex forms, navigating single-page applications (SPAs)—and then you can monitor exactly what happened.
If the task is done, you stop the session and grab the data. This capability means you don't have to worry about infrastructure or scaling; just connect your preferred AI client through Vinkius and let your agent treat websites like they're sitting right in front of it.
019d7564-5e50-7321-9127-cbf5b8da7e98 Here's how it actually works
The bottom line is that this MCP turns your AI agent into an autonomous browser automation system without needing any dedicated hosting infrastructure.
First, you call the tool to create a new browser instance. This returns a unique WebSocket URL required for your automation framework.
Next, your AI agent uses that connection URL with tools like Playwright or Puppeteer to perform actions on the live website, filling forms and navigating pages.
When done, you use another tool to stop the session. You then check the details using a third tool to gather logs, pages visited, or duration.
Who is this actually for?
This MCP solves problems for technical roles who need their agents to interact with modern, JavaScript-heavy websites. It’s for the QA engineer stuck writing tedious Selenium scripts all day, or the data analyst whose scraping job fails because a site requires a login flow.
Uses this MCP to run large batches of browser-based tests across different environments without provisioning any physical test machines.
Connects their agent to execute complex scraping jobs that require JavaScript execution or passing through CAPTCHA-protected forms.
Integrates the session tools into a client application, allowing the AI agent to perform multi-step user flows like registration and data retrieval.
What Changes When You Connect
Instead of writing complex, brittle code to mimic user clicks, you simply use create_browser_session to give your agent a real browser. It handles the connection and session setup for you.
You can monitor everything with list_browser_sessions. This lets developers quickly see if sessions are stuck in an error state or finished successfully, making debugging much faster.
If your job requires accessing content behind JavaScript-heavy logins or complex single-page applications (SPAs), this MCP provides the necessary environment. Your agent gets a full browser context.
Prevent resource leaks and unexpected bills by using stop_browser_session. You can programmatically guarantee that every session is terminated when the task is complete, no matter what.
The combination of tools lets your agent execute multi-stage workflows—for example, logging in with one tool and scraping data with another. It’s a full automation cycle.
See it in action
Need to process form submissions from multiple user roles.
A security team needs their agent to test login flows for admin, basic user, and guest accounts. They use create_browser_session repeatedly to spin up isolated instances for each role, ensuring credentials don't cross-contaminate or interfere with one another.
Scraping data from an e-commerce site that requires session persistence.
A research analyst needs pricing data across 50 different product pages. Instead of failing due to anti-bot measures, they use the MCP to maintain a single, long-running session, simulating continuous browsing and extracting all required information.
Debugging why an agent fails mid-task.
A developer suspects their agent is losing state. They first run list_browser_sessions to confirm the connection status, then use get_browser_session on a specific ID to check the precise pages visited and duration right before the failure point.
Automating bulk content extraction from multiple vendor sites.
A competitor intelligence firm needs to pull product descriptions from 10 different websites. They use the MCP to systematically create, interact with, and then stop a session for each site, ensuring clean resource management across all targets.
The honest tradeoffs
Assuming persistence
Writing code that assumes a browser session remains active indefinitely after the initial create_browser_session call. This leads to 'zombie sessions' consuming resources and incurring unnecessary costs.
Always wrap your workflow logic in resource management patterns. Make sure you explicitly call stop_browser_session when your task is done, even if an error occurs. You can check the status before stopping using get_browser_session.
Over-relying on a single session
Running all test cases—login, search, checkout—on one continuous browser instance. If any step fails or gets stuck, the entire pipeline grinds to a halt.
For distinct functional tests, use create_browser_session for each new process. This guarantees isolation between steps and allows you to track which specific test failed using list_browser_sessions.
Ignoring session details
Simply running a script without ever checking the results or history of what happened in the browser.
After any major interaction, use get_browser_session to check the status and view the pages visited. This confirms your agent reached the expected state before proceeding with data extraction.
When It Fits, When It Doesn't
Use this MCP if your goal is full end-to-end web automation that requires a real, active browser environment—think complex logins, form filling, or JavaScript rendering. Don't use it if you only need to read static HTML data, because for simple scraping of non-interactive content, a pure HTTP request tool will be faster and cheaper.
Conversely, don't rely on this MCP if your workflow is purely internal (e.g., moving data between two databases). For those cases, an API call directly to the database endpoint is always better than spinning up a browser. If you just need to list existing sessions without running anything, list_browser_sessions handles that gracefully.
The key difference: this MCP gives you the client-side context of a user; pure data tools only give you the server's view.
Questions you might have
How do I start using the create_browser_session tool? +
You initiate it by calling create_browser_session. This returns a unique connection URL that your automation framework must use to take control of the new, isolated browser session.
Can I check if my agent successfully completed a task using get_browser_session? +
Yes. You can call get_browser_session with the unique ID to view the current status and detailed history of pages visited, confirming whether the intended action finished correctly.
What is the difference between list_browser_sessions and get_browser_session? +
The list_browser_sessions tool shows you a high-level overview—a roster of all sessions (running, completed, or error). The get_browser_session tool drills down to give specific details about one single session ID.
Should I always use stop_browser_session after my script finishes? +
Absolutely. You must call stop_browser_session when your task is done or if an error occurs. This releases the cloud resources and prevents unexpected costs from 'zombie sessions.'
How do I check for failed or errored sessions using list_browser_sessions? +
You can filter the results by status. Use list_browser_sessions and specify 'ERROR' to pull a list of sessions that crashed or encountered issues during execution, which helps you troubleshoot script failures.
What specific data points does get_browser_session provide about a running session? +
It gives you deep context on the session. You retrieve status details, connection URLs, total pages visited, and the overall duration of the browser activity.
Are there limits to how many sessions I can run with create_browser_session? +
Your capacity is managed by your subscription tier. The service handles scaling for high-volume requests, allowing you to launch multiple isolated instances simultaneously without manual infrastructure setup.
What protocols work with the connectUrl generated by create_browser_session? +
The returned WebSocket URL supports major industry standards. You can connect it directly using frameworks like Playwright, Puppeteer, or Selenium for programmatic control.
How is Browserbase different from Firecrawl? +
Firecrawl is optimized for content extraction — it scrapes pages and returns clean data. Browserbase provides a full browser environment for interactive automation — your agent can click buttons, fill forms, log into websites, scroll, and navigate complex single-page applications (SPAs). Browserbase gives you a real browser, Firecrawl gives you the text from a page.
Which automation frameworks are supported? +
Browserbase sessions expose a CDP (Chrome DevTools Protocol) WebSocket URL, which is compatible with all major browser automation frameworks: Playwright, Puppeteer, Selenium WebDriver, and any tool that supports CDP connections. Simply point your framework at the connectUrl returned when creating a session.
What does the free tier include? +
The free tier includes 1 browser hour, 1 concurrent browser session, and 7 days of data retention. No credit card required. For production workloads, paid plans start at $20/month (Developer) with more browser hours and concurrent sessions.
