Just tried out the puppeteer server example if anyone is interested in seeing a demo: https://x.com/chxy/status/1861302909402861905. (Todo: add tool use - prompt would be like "go to this website and screenshot")
I appreciate the design which left the implementation of servers to the community which doesn't lock you into any particular implementation, as the protocol seems to be aiming to primarily solve the RPC layer.
One major value add of MCP I think is a capability extension to a vast amount of AI apps.
sharing the messy code here just for funsies: https://gist.github.com/xyc/274394031b41ac7e8d7d3aa7f4f7bed9
