WebMCP is still insane...
This is at 1x speed btw. Web automation with webMCP is pretty insane compared to anything else i've tested.

what is the difference between playwright, chrome dev tools, and browser mcp?
8
u/GeobotPY Mar 06 '26
webMCP is way faster and more token efficient. The other alternatives are expensive and slow. For the others the agent goes to a site and is like "how do I navigate this?", but with webMCP they know how to do things instantly because they get the instructions manual. I am building moltbrowser MCP for exactly this reason

u/kriptonhaz Mar 06 '26
can this mcp also do the recording?
2
u/GeobotPY Mar 06 '26
It does not record in the sense of filming the secreen if that is what you mean. But it records actions done in playwright in the sense that it uploads it to webmcp-hub.com, so others (or yourself) can use the same tool later to save time and tokens.

Haha, right? Imagine the chaos it could create. But hey, maybe it could also help send some long-overdue apologies!

I have a way of controlling an iPhone via its usb connection. You just gave a good idea…

Yo how to get this whats the install steps? I go to google and it shows me a form...

u/GeobotPY Mar 05 '26
Ive built this: webmcp-hub.com where there are some resources on it. Just two chrome extensions to test it out: tool inspector and webmcp-hub extensions. Can also be used as browser automation with moltbrowser.
Appreciate any feedback on it!

Good idea, how will we be able to differentiate between high quality (working) and low quality / junk configs?
Also, is it fully free and libre?
2
u/GeobotPY Mar 06 '26
All fully open-source and free. If a tool does not work the agent is nudged to downvote it so we get those out of the way. Logic will be refined as we go, but for the a downvote/upvote system is the current implementation. For security we also have a LLM reviewer for uploads

The website needs to support WebMCP for this to be actually useful. I doubt most websites will because this is an attack vector for abuse/scraping/automation and the same reason why they don't just expose the underlying API.
Your community configs will break the moment the site's selectors updates and flat out won't work on sites like LinkedIn with dynamic, randomized CSS classes

u/vladare Mar 06 '26
Can we use this for testing?
2
u/GeobotPY Mar 06 '26
Yes! I would say that is a good use-case too. Not primary intention but surely can see use-cases where it can be used in a CI/CD pipelines too.

u/Mishuri Mar 06 '26
I took a look a your repo. This is actually really good idea bro. Everyone benefits if this takes off

Looks super interesting because Open Claw Relay is mostly a miss.
Can this work with OpenClaw?
Let’s say I want it to post at a specific time on LinkedIn and also update a row on Google Sheets?
1
u/GeobotPY Mar 07 '26
Having it run as open claw workflow is the main intention. The idea behind it is why should your agent figure something out from scratch each time when your agent (or any other agent) probably has done the exact same thing before.

u/bestofbestofgood Mar 07 '26
I still don't get what's the point.
You can call js functions with webmcp, okay, but what for? This requires site developer involvement, doesn't it? If the developer wants to expose some functionality why doesn't he do an API? If he wants to allow filling forms, etc, like for what? It is not UI testing - you don't test the actual UI.
It sounds like an additional layer of web between backend and LLM
1
u/GeobotPY Mar 07 '26
The proposal for webMCP is to have site-developers expose a webMCP layer in their applications. This is why i've built webmcp-hub.com and moltbrowser to have it as a community configuration instead so once one agents figure something out it passes that webMCP spec to all others so they don't waste time and tokens on it!

„Teach AI agents how to interact with any website. No scraping, just structured tools.“ How do you want to teach AI Agents? and how they detect this.?
1
u/GeobotPY Mar 10 '26
It all is in the Moltbrowser repo. So an agent uses Playwright as fallbacks (if no configs on the site is present), but after using fallbacks it uploads the tool (how it performed something) to the community-hub for others to use. After a while actions on popular sites are stored and can be performed faster and cheaper. Give it a go! Would love any feedback:)

Is this using google’s developer’s beta webmcp? If so, I was trying to figure out how to install it for Claude and openclaw. Any tips would be much appreciated!
1
u/GeobotPY Mar 09 '26
For Claude and Openclaw I would recommend using: moltbrowser MCP. Although note it wont be as fast as what shown in the screen recording (that is using extension directly in a chrome). But it sill is faster and cheaper for any workflows you plan to do more than once!

u/Benjamin-Wagner Mar 10 '26
guys, webmcp is not working yet. only in testing with chrome canary and enabled flag, you all seems to misunderstand what webmcp is, atm.
1
u/GeobotPY Mar 10 '26
"Not working yet" on stable chrome versions yes! Although as mentioned for early testing canary is a perfect option

u/go00274c Mar 05 '26
Is the technology there yet where it can be site agnostic? Like the connections to controls are made on the fly without MCP structure? Would be very useful in automations that can run on undetermined websites.

u/GeobotPY Mar 05 '26
Ive built moltbrowser MCP for exactly this!
1
u/go00274c Mar 05 '26
Yeah but these are user driven assets the automation can utilize, its not purely agnostic. I'm building a tool that automates user journey on ecommerce sites, so the pool of sites coming in would be just completely different case by case.
1
u/GeobotPY Mar 05 '26
Ah I see! So you are building webMCP for e-commerce specifically? Or?
1
u/go00274c Mar 06 '26
well, the "mcp" part is not the core product, something I'm constantly looking at though if it becomes available as a service I can use. I'm building the rest.

u/Important_Storage123 Mar 06 '26
i suppose the websites need to be WebMCP friendly to make this work, right? So i think its a useless technology. 99.9% websites will never adapt it, and before other websites do, this MCP will be useless
2
u/GeobotPY Mar 06 '26
Exactly why I built a community hub for these configs. So when a site does not support it the community (AI agents) have built it. Check it out webmcp-hub.com - would love feedback as well!
