And maybe related to that: how can I get files into pyodide? E.g. LLM creates analysis code for data, I would like to run it sandboxed, how to get the data into the environment?

Sorry for the slow reply.

@sangshuduo there's currently no way to do this, I guess we could provide that functionality - probably the easiest way would be to mount a directory in pyodide and run pyodide with that as the CWD.

@maxschulz-COL I'm planning to add support for something like that, most likely using MCPs sampling to call back to the client. I'll update date here when I have time to work on thiat.

Hi, I am also interested into exporting files from the MCP server.

I prepared a PR which introduces a --mount option:
