01 · Install NOAA Tides and Currents

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add ryancardin15-perigee-tides --transport http https://perigeetides.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ryancardin15-perigee-tides": {
      "url": "https://perigeetides.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to perigeetides.com

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

npm package @ryancardin/noaa-tides-currents-mcp-server - the @ryancardin scope differs from the repo owner (ryancardin15); confirm it's the project's official package

registry namespace io.github.RyanCardin15 is GitHub-verified and matches the repo owner

Tools grouped from the project's README - what NOAA Tides and Currents lets an agent do.

Noaa

18 tools - e.g. Observed water levels: 1-minute, 6-minute, or hourly series, preliminary/verified quality flags decoded; high_low (HH/H/L/LL daily extremes), daily_mean (Great Lakes), daily_max_min, monthly_mean datum…

Astro

5 tools - e.g. Phase, illumination, age, distance for a date or range (spring/neap tide context); Next new/full/quarter moon date(s); Sunrise/sunset, twilights, golden hour, day length for any location/date

astro_get_moon_phase · astro_get_next_moon_phase · astro_get_sun_times · astro_get_sun_position · astro_get_next_sun_event

Nws

2 tools - e.g. Hourly numeric wind forecast (speed/gust/direction, wave height where gridded) for any US lat/lon, up to ~7 days; Official Coastal Waters Forecast narrative for the marine zone covering a lat/lon, incl.…
