Hobby Market Oracle

An MCP server that gives AI agents live answers about the collectibles market: is this price scalped, was it recalled, is it back in stock, what's a card's rough grade, and which class-action settlements can I claim. Agents discover these tools and call them — no scraping, no glue code.

Tools the agent gets

check_scalper_priceCheck whether a hobby item's asking price is fair or scalped.
check_recallSearch active consumer product recalls (CPSC, FDA, NHTSA and more) by keyword.
check_in_stockCheck whether a hobby item has recently dropped or restocked across the specialty shops we monitor for a niche.
grade_card_centeringEstimate a trading card's centering and rough PSA-style grade from a photo.
find_settlementsFind open class-action settlements you may be eligible to claim (often no proof of purchase required).
