browserrepl.com is the now and the future

when will vercel mcp allow any client to connect, not just their supported clients?
i dont understand why this became a thing popular companies did with their mcp servers to begin with

KERNEL now supports @1password for agents. your agent can sign in without ever seeing your password.
it asks for the login it needs. you approve the request in 1password. the password goes straight into the KERNEL browser and never to the agent.
bot detection is fundamentally flawed
it used to be that all bots were bad and none should get in. now non-human actors on the internet drive real traffic and revenue
this will only continue to grow, we are entering a new era of fraud detection
Bot detection & human verification will be one of the most urgent demands for businesses over the coming years. Agent swarms will suffocate every website and form; small companies and government websites are most vulnerable.
There is a huge gap in the market for this right now. When we looked at what offerings were in the market to use at X, there was not a single company that brought together all the latest technologies so we had to do it all in-house.

this is awesome, webmcp is going to entirely change how agents use browsers
webmcp fully supported on our browsers btw
We just rolled out support for WebMCP across @stripe Checkout UIs.
In our benchmarking we saw 42% fewer tokens consumed and 38% fewer tools invoked when an agent had access to WebMCP when completing a payment.

first we release proxy v3. that unlocked the ability to explore the world of egress proxy token replacement.
now we leveraged egress proxy to solve secure checkout on a KERNEL browser.
your browser agents can now complete online purchases without ever touching card data.
agents on KERNEL now pay on checkout pages using aliases, not card data. we swap in the real credential at egress, so card numbers never touch your agent's runtime or context.

the KERNEL bunker is the safest place to be during launches
i built a 3D simulator for @usekernel browsers w/ astra. you can log in and open a real browser like it’s hardware on a desk and converse with the agent via keyboard or voice to control it.

my agent bought me the wrong flight
solution is simple: introducing Agentcard Vault. share your card safely with your agent and buy anything online
- use any card (including Chase)
- share it with any browser, like @usekernel
- approve transactions with Face ID
- native integration with @thelinqapp
- store more than cards (passports, login credentials and more)
- PCI compliant
the KERNEL mcp has improved drastically over the past month with more on the way
it gives your agent the ability to take action on the internet for you
if you haven't tried it, now is the time
fx.sh 0.0.7:
- hugely improved MCP support, eval'd with top MCPs like @context7ai, @datadoghq, @mongodb, @linear, @notionhq, @supabase, @neondatabase, @stagehanddev, @usekernel…
- more minimalist: fewer tools and improved shell execution. One of the trickiest things about CLI agents is that running commands is actually not that simple.
e.g: commands might hang or run for very long, their output needs to be monitorable by the agent, they might produce huge amounts of output, or none.
This is an area where 𝚏𝚡 really shines and will continue to get better.
