btwExtra
by brianmsm
Overview
Provides an MCP server for R, allowing LLMs to execute arbitrary R code and access additional R-specific tools.
Installation
Rscript -e "btwExtra::btwExtra_mcp_server()"Security Notes
The primary security risk is the `btwExtra_tool_env_run_r_code` tool, which explicitly allows running arbitrary R code in the connected R session. This means an LLM or a malicious actor could execute system commands (e.g., `system('rm -rf /')`), access/modify files, or perform network operations through the R interpreter without any apparent sandboxing mechanisms described. While this is an intended 'escape hatch' feature, it carries significant inherent security risks if the LLM's output is not strictly controlled or audited.
