Instructions
## Overview The mcptools package uses nanonext for inter-process communication between the MCP server and R sessions. nanonext provides asynchronous messaging using the nanomsg/nng protocols. The full plain-text MCP specification lives in `.md` files in `inst/spec/`—tool call for it as needed. ## Key Concepts ### Asynchronous I/O (Aio) - `send_aio()` and `recv_aio()` return immediately without blocking - Operations complete asynchronously in the background - Use `unresolved(aio)` to check if an operation is still pending - Access results via `aio$data` (recv) or `aio$result` (send) ### Socket…
