io.github.mansurjisan/ndbc-mcp — MCP Server for NOAA NDBC Observations

This Model Context Protocol (MCP) server provides NOAA National Data Buoy Center observations for ocean and weather variables. It focuses on waves, sea surface temperature (SST), wind, and pressure, sourced from 1,300+ stations. The server exposes these datasets for developer access.

🛠️ Key Features

Observations covering waves
Observations covering SST (sea surface temperature)
Observations covering wind
Observations covering pressure
Coverage from 1,300+ stations (NOAA NDBC)

🚀 Use Cases

Retrieve buoy observation data for waves, SST, wind, and pressure
Support applications that need near-real-time or historical environmental conditions from buoy stations

⚡ Developer Benefits

Single MCP server interface for multiple NOAA NDBC observation types
Dataset grounded in NOAA National Data Buoy Center station coverage (1,300+ stations)

⚠️ Limitations

Limited to NOAA NDBC observation categories listed: waves, SST, wind, pressure

OceanMCP

A monorepo of independently installable MCP servers for ocean and coastal data workflows.

No API keys required for the data servers — all servers above use free, publicly available datasets. The exceptions are hpc-system-mcp and ufs-runner-mcp (below), which require actual NOAA RDHPCS cluster access and, in ufs-runner-mcp's case, submit real Slurm jobs.

Additional servers live in this repo but are not yet published to PyPI (install from source): vdatum-mcp (vertical datum conversion), hpc-system-mcp and ufs-runner-mcp (NOAA RDHPCS / UFS-Coastal HPC workflows — require cluster access), and alert-mcp (CO-OPS threshold alerting).

There is also a 19th server in this repo, nos-workflow-mcp, which is experimental and still a work in progress (its full implementation lives on an unmerged branch — main carries only a minimal subset). It's intentionally left out of the table above and not yet ready for general use.

Quick Start

Install from PyPI

bash

# uvx (recommended) — runs without permanent install, like npx for Python
uvx coops-mcp

# pip — install into current environment
pip install coops-mcp

# pipx — install in isolated environment with CLI entry point
pipx install coops-mcp

Replace coops-mcp with any published server: erddap-mcp, nhc-mcp, recon-mcp, stofs-mcp, ofs-mcp, rtofs-mcp, ww3-mcp, ndbc-mcp, winds-mcp, usgs-mcp, goes-mcp, adcirc-mcp, schism-mcp.

Install from source

bash

git clone https://github.com/mansurjisan/ocean-mcp.git
cd ocean-mcp/servers/coops-mcp  # or any other server directory under servers/
uv sync

Architecture

Each server is fully self-contained with its own pyproject.toml, dependencies, and tests. See docs/architecture.md for details on shared conventions.

Shared patterns across servers:

FastMCP for MCP server framework
httpx for async HTTP clients
Pydantic models, with Literal[...] types for constrained parameters
Read-only tools by default — the data-fetching servers only fetch, never modify, anything. ufs-runner-mcp (submits/cancels Slurm jobs) and alert-mcp (creates/pauses/deletes in-memory alert state) are the two exceptions, each with a small number of tools marked readOnlyHint=False
response_format output as markdown (default), json, geojson, or image, depending on the tool
Actionable error messages with suggestions

See CONVENTIONS.md for the full response/behavior contract (output caps, retrieved_at, error format, HTTP retries, dependency bounds).
