Introducing acquaint, an R package that turns your R sessions into a Model Context Protocol (MCP) server. This allows MCP-enabled tools like Claude Desktop and Claude Code to run #rstats code _in your active R sessions_ to explore objects, read documentation, etc. posit-dev.github.io/acquaint/

Hey Simon! This is awesome, really excited to try this out! Are there any risks with sensitive information or environment variables being passed in to the prompts/metadata via the MCP server and do you have any recommendations for using the MCP server safely?

This is indeed a risk. We've configured a default set of tools that we feel are atomic and reduce risk, rather than some sort of general `run_r_code()` tool. In general, I'd recommend only using model providers that satisfy your privacy needs, i.e. that you're comfortable passing your data to.
