/setup-mcp
Connect the MarketCheck MCP server — one command, no npm, no local processes
Purpose
The MarketCheck MCP server provides the live inventory, pricing, VIN decode, and market data APIs that power all skills in this plugin — from run list pricing to consignment sourcing to lane planning. Without it, skills can describe what they would analyze but cannot pull real data.
/setup-mcp configures the MarketCheck MCP server in one step. It finds or creates the appropriate config file, merges the MarketCheck entry while preserving any existing MCP servers, and instructs you to restart Claude Code to activate the connection.
Arguments
API_KEYoptionalYour MarketCheck API key. If omitted, the command will prompt for it.
How It Works

Uses $ARGUMENTS as key or prompts. Points to marketcheck.com for key acquisition.
