NOAA Tides and Currents MCP Server

This is an MCP (Model Context Protocol) server that provides tools for interacting with the NOAA Tides and Currents API using the FastMCP framework.

Features

• Water Level data retrieval (real-time and historical)
• Tide Predictions (high/low or interval-based)
• Currents data (real-time and historical)
• Current predictions
• Station metadata retrieval
• Wind, air temperature, water temperature, and other meteorological data

Prerequisites

• Node.js (v18 or higher)
• npm or yarn

Setup

1. Clone this repository
2. Install dependencies

3. Create a .env file based on the .env.example file:

4. Build the TypeScript code

5. Start the server

Usage

This MCP server can be used with any MCP host such as Claude Desktop, which allows you to use the NOAA Tides and Currents API through the MCP protocol.

You can also test it directly using the fastmcp command-line tool:

Or, you can use the MCP Inspector:
