get_marine_conditions
Wave height, swell, ocean currents, Douglas Sea Scale — includes Great Lakes and major US bays; forecast up to 16 days
How to use it
get_marine_conditions is exposed by the Weather MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the get_marine_conditions tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
