TCG MCP

seanlok/tcg-mcp

Brings Pokemon TCG collection management into Claude via 25 tools spanning PSA grading lookups, local SQLite storage for your cards, and multi-provider pricing through Pokemon TCG API and PriceCharting. You can pull cert images and population data, track raw and graded cards with cost basis, snapshot market prices over time for trend analysis, and maintain a watchlist with target buy prices. Everything lives in a local database you control. CGC and BGS are stubbed for now but the provider architecture is already wired up. If you're tracking PSA slabs or building a position in specific cards, this gives Claude direct access to grading data and pricing history without manual data entry.
