# mcp-buy123-vendor `mcp-buy123-vendor` is an open-source [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server for the buy123 vendor portal. It gives AI clients such as Claude Desktop, Claude Code, and other MCP-compatible agents read-only tools for querying vendor operations data, including orders, returns, shipments, products, bundles, channels, inventory, permissions, and vendor profile records.
