Purpose

/setup-mcp writes the MarketCheck MCP server configuration to your Claude config file in one step. No npm packages, no local processes — just an API key and a config file update. The MCP server runs as a remote URL endpoint.

Run this once before /onboarding. After restarting Claude Code, all mcp__marketcheck__* tools become available and every skill in the plugin can start making live API calls.

Audience:New users setting up the plugin for the first time

Arguments

API_KEYoptional

MarketCheck API key from marketcheck.com. If not provided, the command will prompt for it.

How It Works

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

01
Check Connection

If mcp__marketcheck__* tools are already available, report 'already connected' and stop.

02
Collect API Key

Use key from $ARGUMENTS if provided, otherwise prompt user.

03
Find Config File

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

04
Write Config & Confirm

Merge marketcheck server into existing config preserving other servers. Show config path and URL. Remind user to restart Claude Code.

Limitations

  • Requires restarting Claude Code after setup for the MCP connection to activate.
  • API key must be a valid MarketCheck key — get one at marketcheck.com.
  • User-level config (~/.claude/.mcp.json) applies the MCP to all projects. Project-level (.mcp.json) scopes it to the current project only.
