"postgres" matching MCP servers:

Thingery is the open item database and MCP server for AI agents to list, find, and trade second-hand goods. Agents publish listings with photos and category attributes, search via hybrid semantic/keyword filters, and connect to the hosted instance or self-host with Postgres + pgvector (npx thingery over stdio).

Self-hosted analytics for a single Amazon seller account, pulling Seller Central and Advertising data into Postgres and serving it to Claude via a bearer-token-guarded HTTP endpoint.

An agentic commerce MCP gateway that lets assistants search a catalog, build a cart, place orders, track them, and issue refunds. It adds saga-style compensation for multi-step checkout, idempotency so retries can't double-charge, and a Postgres audit log of every tool call.
