### Description (declared)

Surfing Dog is a public directory of businesses that AI agents can reach through doors the businesses published: an agent inbox, MCP, A2A, an API, UCP or ACP. Use search_businesses when a person wants to find a business, get_business for one business's details and doors, and check_business when a person asks how far an agent can go with a particular business's website. Talk to a business at its own doors; this directory takes nothing.
