Purpose

The MarketCheck MCP server provides all the live market data APIs that power this plugin. Without it connected, skills can describe what they would do but cannot pull real data. Setup requires writing a single JSON configuration entry pointing to the MarketCheck API endpoint — no package installation, no local server, no Docker.

/setup-mcp handles the entire configuration: it finds or creates your MCP config file (~/.claude/.mcp.json or .mcp.json), merges in the MarketCheck server entry while preserving any existing MCP servers, and confirms the configuration path. After restarting Claude Code, all mcp__marketcheck__* tools become available and every skill in the plugin runs with live data.

Audience:All new usersAnyone setting up a new machine or project

Arguments

API_KEYoptional

Your MarketCheck API key from marketcheck.com. If omitted, the command will prompt for it.

How It Works

Execution flow. MCP tool calls are shown inline on each step.

01
Check Existing Connection

Checks if mcp__marketcheck__* tools are already available. If yes, confirms already connected — no action needed.

02
Collect API Key

Uses $ARGUMENTS as API key if provided. Otherwise prompts. Directs to marketcheck.com if key not yet obtained.

03
Find Config File

Checks ~/.claude/.mcp.json (user-level) then .mcp.json (project-level). Creates ~/.claude/.mcp.json if neither exists.

04
Write Config

Merges MarketCheck server entry into existing config — preserves all other MCP servers already configured.

05
Confirm & Instruct

Shows server URL and config file path. Instructs user to restart Claude Code for connection to take effect.

Example Output

MCP SETUP — MarketCheck
═══════════════════════

MarketCheck MCP configured successfully.

  Config file:  ~/.claude/.mcp.json
  Server name:  marketcheck
  Server URL:   https://mc-api.marketcheck.com/mcp?api_key=••••••••

NEXT STEPS
  1. Restart Claude Code to initialize the MCP connection
  2. Run /onboarding to set up your manufacturer profile
  3. Try: "Market share for Toyota in Texas"
  4. Try: "Regional demand heatmap for California"

After restart, all mcp__marketcheck__* tools will be available.

Limitations

  • Requires a valid MarketCheck API key — available at marketcheck.com.
  • Requires restarting Claude Code after configuration for the MCP connection to initialize.
  • User-level config (~/.claude/.mcp.json) applies to all projects; project-level (.mcp.json) applies only to the current project.
