Functions exposed to the LLM to take actions

Name	Description
list_portsA	List serial ports, including the simulator, with a best-guess chip identification.
board_infoB	Chip family, flash size, MAC address, and MicroPython version (if any) for `port`.
flash_firmwareA	Write `firmware_path` to `port`. Reports progress at least every 5% via MCP progress notifications and can be cancelled mid-flash. `erase=True` wipes the whole flash first and requires `confirm_erase=True` as a separate explicit argument.
repl_execA	Run `code` on `port` over MicroPython's raw REPL; stdout/stderr/exception come back separately.
fs_lsB	List a directory on the board's filesystem.
fs_getA	Read a file from the board. Content comes back base64-encoded; refuses files over max_bytes.
fs_putA	Write a base64-encoded payload to a file on the board, chunked over several raw-REPL exchanges.
tail_serialA	Capture raw serial output for up to 30 seconds without going through the REPL protocol.
