MCP endpoint (Streamable HTTP)

JSON-RPC 2.0 over Streamable HTTP, speaking the Model Context Protocol.

Stateless: no sessions, no session ids, no resumable streams, and GET is not served. Thirteen read-only tools over public data: search_items, get_item_details, find_deals, get_new_limiteds, get_creator, rank_creators, rank_players, get_player_holdings, get_community_holdings, find_articles, get_started_guide, get_market_stats, get_market_cap.
