Use it from Claude Code, Cursor and other AI agents

There's a remote MCP server, so coding agents can call the catalog as tools: search_cards, get_card, list_cards_in_set, list_sets, get_set, and get_api_key for an agent that needs to sign itself up.

# Claude Code
claude mcp add --transport http master-setter https://api.master-setter.com/mcp \
  --header "Authorization: Bearer $KEY"

// Cursor: ~/.cursor/mcp.json
{ "mcpServers": { "master-setter": {
    "url": "https://api.master-setter.com/mcp",
    "headers": { "Authorization": "Bearer YOUR_KEY" } } } }
