Beach Day API for AI agents

Beach Day API provides data on beaches worldwide, including conditions, scores, amenities, rules, and tide predictions, used by apps that help people plan a beach trip. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.
