Related. We have several third party web apps in use. These apps don't expose a public api, but they are all single page web apps. We wanted to connect claude code to these web apps for our limited use case.

We opened chrome, navigated the entire website, the downloaded the network tab as an har file. The asked claude to analyze and document the apis as an openapi json. Worked amazing.

Next step - we wrote a small python script. On one side, this script implements stdio mcp. On the other side, it calls the Internal apis exposed by the 3rd party app. Only thing missing is the auth headers..

This is the best part. When claude connects to the mcp, the mcp launches a playwright controlled browser and opens the target web apication. It detects if the user is logged in. Then it extracts the auth credentials using playwright, saves them to a local cache file and closes the browser. Then it accesses the apis directly - no browser needed thereafter.

In about an hour worth of tokens with claude, we get a mcp server that works locally with each users credentials in a fairly reliable manner. We have been able to get this working in otherwise locked down corporate environments.

Super cool. I think this is where most automation is heading . Would be curious if you could one-shot the auth flow using Kampala and completely ditch the browser. Also FWIW you can import HAR into Kampala and we have a few nice tools (like being able to a/b test payloads/replay requests) that meaningfully reduce integration time.

5 years ago I used a similar approach for one of GCPs internal APIs (I think they've since released a public API that covers the use case I had). Was a bit of a pain to do manually, so it's cool to see how trivial this has become for models now.

Smart! That's what I do as well for customers when they ask me to build a vibe coding layer on top of their SaaS platform.

Takes very little time and tokens and I get to plug into their platform in seconds.
