LocalTides 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
• Moon phase information (past, present, and future)
• Sun rise/set and position data (past, present, and future)

Prerequisites

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

Setup

Installing via Smithery

To install NOAA Tides and Currents for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @RyanCardin15/tidesandcurrents --client claude

Manual Installation

1. Clone this repository
2. Install dependencies

npm install

3. Build the TypeScript code

npm run build

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:

npx fastmcp dev dist/index.js

Or, you can use the MCP Inspector:

npx fastmcp inspect dist/index.js
