marketplace-mcp

A dual-dialect NOSTR marketplace publisher MCP server that enables agents to create and update marketplace events. It supports NIP-15 stalls and products as well as Shopstr-modern shop profiles and NIP-99 classified listings. The server includes an automatic cache-POST mechanism to ensure events appear on the Shopstr storefront, addressing the limitation that Shopstr is a Postgres-backed CMS that only renders events from its own DB.
