# Version 0.3.26

> February 19, 2026

## <u>Features</u>

### MCP Server for AI Assistant Integration

Full Model Context Protocol (MCP) server enabling AI assistants to control Lager hardware directly:

* **165+ tools** across 21 modules covering all Lager CLI functionality: power supplies, batteries, solar simulation, electronic loads, I2C, SPI, UART, BLE, WiFi, USB, ADC, DAC, GPIO, oscilloscope, debug, robotic arm, webcam, and more
* Run with `python -m cli.mcp` or `mcp dev cli/mcp/server.py`
* Built on FastMCP with subprocess-based CLI wrapping for reliable operation
* Power supply and battery tools auto-pass `--yes` to skip confirmation prompts for safe automated operation

### MCP Test Suite

Comprehensive test coverage for the MCP server:

* **254 unit tests** with mocked subprocess calls (no hardware required, runs in \~0.6s)
* **64 integration tests** against real Lager Boxes covering power, battery, eload, I2C, SPI, ADC, DAC, GPIO, USB, and defaults
* Safety fixtures auto-disable power output in test teardown

## <u>Improvements</u>

* Cleaned up LabJack T7 SPI driver code
