This is really well done! Very cool.
I wonder if it's possible to add such plugins to election apps (e.g.: Slack). It would be such a nice experience if I could just connect my AI of choice to a local app.

#22So is MCP the new RPA (Robotics Process Automation)? Like generic yahoo pipes?
No, since MCP is just an interface layer it is to AI what REST API is to DPA and COM/App DLLs are to RPA.
APA (Agentic Process Automation) is the new RPA, and this is definitely one example of it.

#23I just run into a bunch of errors on my Windows machine + Chrome when connected over remote-ssh. Extension installed, tab enabled, npx updated/installed, etc.

EDIT: Ended up fixing it by patching index.js. killProcessOnPort() was the problem. Can hit me up if you have questions, I cannot figure out how to put readable code in HN after all these years with the fake markdown syntax they use.

I just view it as a relative minor convenience, but it's not some game-changer IMO.
The tool use / function calling thing far predates Anthropic releasing the MCP specification and it really wasn't that onerous to do before either. You could provide a json schema spec and tell the model to generate compliant json to pass to the API in question. MCP doesn't inherently solve any of the problems that come up in that sort of workflow, but it does provide an idiomatic approach for it (so there's a non-zero value there, but not much).

#26I like this. It would be interesting to use it for when I need to use authenticated browser sessions.

#27Why use this over Puppeteer or Playwright extensions?
The Puppeteer MCP server doesn't work well because it requires CSS selectors to interact with elements. It makes up CSS selectors rather than reading the page and generating working selectors. The Playwright MCP server is great! Currently Browser MCP is largely an adaptation of the Playwright MCP server to use with your actual browser rather than creating a new one each time. This allows you to reuse your existing Ch…
by the way, you can indeed access your personal context with Playwright. just `launchPersistentContext()` and set the userDataDir to that of your existing Chrome install:

Oh good idea.
Imagine it controlling plugins remotely, have an LLM do mastering and sound shaping with existing tools. The complex overly-graphical UIs of VSTs might be a barrier to performance there, but you could hook into those labeled midi mapping interfaces to control the knobs and levels.

It's a developer tool
