Thanks for the PR we do not plan to support HTTP right now because we do not have multi-session support that in my understanding would be required for the HTTP transport (and it looks like this PR does not add it). Could you please elaborate on your use case? Is it not solvable with an MCP proxy? Are you looking to manage multiple Chrome instances with a single MCP server? If you share your use case, it would help us prioritize supporting the HTTP transport. cc @natorion |
Yeah, exposing this MCP via http could be solved with a proxy that will adapt http to stdio. I'm looking to run this on a container somewhere then access it via http. Managing multiple chrome instances would also be nice, since i would also probably want to make this multi tenant separating the sessions through some auth header, which i believe is also what you mean with the multi session support. But i'm not sure what would be the ideal approach here. i've read on the --help that there is an option for me to connect to specify a remote chrome socket uri for connecting, so maybe i could also do something like running the multiple chrome instances somewhere else then having this single MCP server route people for the different sockets? idk. With this setup that i've just sent you via pull request, i was able to run it locally with a http proxy tunnel on top of it and plug it on agents that i use on the web, that would not have access to my computer usually (since it's an arbitrary web server connecting to my chrome mcp). I also can just run two proxies i guess. A use case of mine would be to provide people with an MCP server they can connect to an agent to look for improvement opportunities on a ecommerce page load, looking at the network tab, image/javascript loading priorities etc. This agent would be running remotely, being accessed via browser and require no local setup, being able to also edit code in some remote environment running a dev server. Just like something like https://replit.com/ works. I got interested on running multiple chrome instances, though, if you think it makes sense i would like to implement it, seems that it would be useful for me. |

Yes, currently, one MCP server instance is tied to a single Chrome instance. With

Closing the PR as it has merge conflicts now. But the http transport discussion is still ongoing for us and we will try to resolve it as part of #926 For now using an mcp proxy e.g., |
I think we should make this option more prominent, right now its buried inthe Katalon Studio configs. |
