Crate gallo_mcp 

gallo-mcp — an MCP server exposing a Pico de Gallo device to AI agents.

Wraps pico_de_gallo_lib::PicoDeGallo and presents one MCP tool per peripheral operation over stdio. Bytes cross the tool boundary as hex strings (in) and encoding::Bytes (out). Write/actuation tools are annotated destructive_hint = true; approval is delegated to the MCP client.

Modules

adc

ADC tools.

device

Device-level tools: enumeration, status, info, version, ping.

encoding

Byte-payload encoding and argument validation for MCP tools.

error

Mapping from pico-de-gallo-lib errors to rmcp::ErrorData.

gpio

GPIO tools (timeout-bounded edge waits only; no subscriptions).

i2c

I2C tools.

onewire

1-Wire tools.

pwm

PWM tools.

spi

SPI tools.

uart

UART tools.

Structs

GalloMcp

The MCP service. Holds only the device selector and a connection lock; the USB connection is opened per tool call by GalloMcp::connect and released when the call completes, so the board is free for other host processes between calls.
