Does anyone know if there is work on the idea of letting MCP-like "servers" run on the client-side? I.e. in the same browser tab as ChatGPT or Claude?

This specific example would make much more sense if it could run sandboxed client-side.

all of the servers deployed to mcp.run[0] are Wasm modules, and can run client side. they run in our cloud too, but you could use mcpx to pull them locally instead.

you can also get the raw wasm via our API and run them anywhere you can run Extism[1], the open source wasm runtime & framework that underpins it all. (Including this hyper-mcp project!)

Sounds cool. We already have browser use though!

You can also roll your own with selenium and c vision or selectors.
