How to connect
These Coastal / Tides & Sun tools use the same LiveDataLink endpoint as the rest of the catalog. Add it to an MCP client that supports Streamable HTTP and include your bearer key. Each source has its own coverage, update schedule, and credential requirements; those limits are listed in the catalog and response notes.
