MCP Tools (Use These First)

MANDATORY: ALWAYS use MCP tools directly instead of the shell.

Components

CLI (mech)

Command-line interface for all operations:

• mech lint <addon> - Run Luacheck
• mech format <addon> - Run StyLua
• mech test <addon> - Run Busted tests
• mech release <addon> <version> "<message>" - Full release workflow

MCP Server

Exposes 53 AFD commands as MCP tools for AI agents. All functionality available via mech call <command> is also available as MCP tools.

Dashboard

Web UI at http://localhost:5173:

• Real-time SavedVariables sync
• Reload trigger button
• Error/test/console log viewer

In-Game Modules

The !Mechanic addon provides:

• Console - Aggregated print output from all registered addons
• Errors - BugGrabber integration for Lua error capture
• Tests - In-game test results from MechanicLib tests
• Inspect - Frame inspector for UI debugging
• API Bench - Performance testing for WoW APIs

MechanicLib Integration

Addons register with Mechanic via MechanicLib:

local ML = LibStub("MechanicLib")
ML:RegisterAddon("MyAddon", {
    version = "1.0.0",
    Print = function(...) ML:Print("MyAddon", ...) end,
})
