Setup
Setup guide
- 11. Open your Switchy workspace and navigate to Settings > Integrations. 2. Find Browserbase MCP in the catalog and click Connect. 3. Log into your Browserbase account (or sign up at browserbase.com if you don't have one). 4. Generate an API key from the Browserbase dashboard under API Keys. 5. Paste the key into Switchy's connection dialog and click Authorize. 6. Switchy confirms the connection and shows Browserbase as active. 7. Open any Project and type '@Browserbase navigate to example.com and screenshot the homepage' to test — the AI will launch a session, load the page, and return the image. 8. Check your Browserbase dashboard to see the session logged and billed. 9. If the test fails, verify the API key has not expired and your Browserbase plan has available session credits.
What teammates see: by default, memories from Browserbase MCP are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

How Switchy teams use it
Starter prompts
Capture Competitor Homepage
@Browserbase navigate to acme-competitor.com and capture a full-page screenshot in desktop viewport
Extract Pricing Grid
@Browserbase go to competitor.com/pricing, wait for the pricing table to load, then extract all plan names and monthly prices
Test Login Flow
@Browserbase navigate to staging.myapp.com/login, fill email with test@example.com, fill password with demo123, click submit, and report any error text
Monitor Page Load Time
@Browserbase load dashboard.myapp.com and report the time to interactive metric from the performance API
Scrape Job Listings
@Browserbase open careers.company.com, scroll to the bottom to load all listings, then extract job titles and locations
Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@Browserbase visit the last five URLs from our #competitor-research channel, extract each page's H1 and meta description, then summarize common messaging themes
Visited five competitor URLs in parallel sessions. Extracted H1 headlines and meta descriptions from each page. Common themes identified: four of five emphasize 'enterprise-grade security', three mention 'seamless integration', two highlight 'AI-powered insights'. Full extraction data attached as structured JSON for further analysis.
Showcases Browserbase's ability to handle multiple concurrent sessions and pair browser automation with AI reasoning. Parallel execution speeds up batch tasks. Note that rate limits apply to session creation (check your plan tier). This workflow combines raw extraction with LLM synthesis for competitive intelligence.
Use-case deep-dives
When Browserbase MCP speeds up pre-launch visual checks
A 5-person SaaS team ships every two weeks and needs screenshots of the staging app across browsers before each release. Browserbase MCP lets you script headless browser sessions that capture visuals or run smoke tests without maintaining local Selenium grids. The API key setup takes under five minutes, and you can trigger sessions from Switchy threads tied to your release checklist. This works well if you're running fewer than 50 sessions per sprint—beyond that, you'll want dedicated CI infrastructure. If your QA process is already automated in GitHub Actions, Browserbase might duplicate effort. But for teams doing manual checks today, this MCP turns a 30-minute ritual into a two-minute command.
How this MCP handles lightweight competitive intelligence
A three-person growth team at a B2B startup checks competitor pricing pages weekly to spot plan changes or new features. Browserbase MCP can automate those visits and return rendered HTML or screenshots, so you're not manually opening tabs every Monday. The catch: if competitors use heavy JavaScript or bot detection, you'll need to configure session parameters carefully, and that's not always exposed through the MCP layer. This scenario works best when you're tracking 5-10 static pages and don't need complex interaction flows. If you're scraping dynamic dashboards or need to bypass CAPTCHAs, you'll outgrow this quickly. For straightforward page snapshots tied to a weekly Switchy thread, it's a clean fit.
When Browserbase MCP replaces manual onboarding walkthroughs
A 7-person customer success team onboards 20 new accounts per month and wants to verify that each customer's unique subdomain loads correctly after provisioning. Browserbase MCP can script a login and navigation sequence, returning success or failure signals without a CS rep clicking through manually. This is useful if your onboarding flow is stable and you're checking for regressions, not exploring edge cases. The API key model means you can delegate session triggering to non-technical team members via Switchy. If your onboarding involves file uploads, payment forms, or multi-step OAuth, the MCP might not expose enough control. For simple load-and-verify checks, it cuts onboarding QA from 10 minutes per account to zero.
Frequently asked
What does the Browserbase MCP do in Switchy?
It connects Claude to Browserbase's headless browser infrastructure, letting your AI agents interact with web pages, run JavaScript, take screenshots, and extract data from sites that require rendering. Think of it as giving Claude a real browser to work with instead of just fetching static HTML.
Do I need a Browserbase account to use this MCP?
Yes. You'll need an active Browserbase account and an API key from their dashboard. The MCP uses API key authentication, so whoever sets it up in Switchy needs access to generate keys in your Browserbase project settings. No OAuth flow — just paste the key during setup.
Can this MCP interact with sites that require login or cookies?
Yes, if Browserbase supports session persistence for your use case. The MCP inherits whatever capabilities Browserbase exposes through their API — typically including cookie management and authenticated sessions. Check Browserbase's own docs for limits on session duration and storage.
Why use this instead of just asking Claude to fetch a URL?
Claude's native web access can't run JavaScript, handle dynamic content, or interact with pages the way a real browser does. Browserbase gives you a full Chrome instance in the cloud, so you can scrape SPAs, automate form fills, or grab data from sites that block headless scrapers.
Does using this MCP count against my Browserbase plan limits?
Yes. Every browser session Claude spins up through this MCP consumes your Browserbase quota — session minutes, concurrent browsers, whatever your plan tracks. One team member connects it in Switchy, but the whole workspace shares that Browserbase account's usage.
