SellOracle MCP Server

Pre-computed Etsy market data for AI agents — real Blue Ocean niche scores, demand & competition signals, best sellers, and top shops, served over one remote MCP server and a REST API.

Stop letting your agent make up Etsy numbers. SellOracle aggregates 45K+ listings into niche-level conclusions (a 0–100 Blue Ocean score per keyword, computed weekly from four signals: demand, saturation, concentration, freshness) so your agent gets the answer in one call instead of scraping and re-deriving.
