The profile adds an optional commerce extension to the Server Card, carried in the Server Card's \_meta object under the reverse-DNS key com.beaconspec/commerce, for commercial businesses operating MCP servers. The extension carries business identity, geographic location, industry classification, offering type, and advertised capability categories. The purpose of the profile is to give AI agents enough machine-readable information about a commercial MCP server to filter, select, and bootstrap an interaction without first opening an MCP session against every candidate server.}, }
