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/oceanmodeling/ocean-mcp.git cd ocean-mcp/servers/coops-mcp # or any other server directory under servers/ uv sync ``` ### Configure your MCP client Add to your MCP settings (e.g., project `.mcp.json`): **Using PyPI packages (recommended):** ```json { "mcpServers": { "coops": { "command": "uvx", "args": ["coops-mcp"] }, "erddap": { "command": "uvx", "args": ["erddap-mcp"] }, "nhc": { "command": "uvx", "args": ["nhc-mcp"] }, "recon": { "command": "uvx", "args": ["recon-mcp"] }, "stofs": { "command": "uvx", "args": ["stofs-mcp"] }, "ofs": { "command": "uvx", "args": ["ofs-mcp"] }, "rtofs": { "command": "uvx", "args": ["rtofs-mcp"] }, "ww3": { "command": "uvx", "args": ["ww3-mcp"] } } } ``` <details> <summary>Using local source checkout</summary> ```json { "mcpServers": { "coops": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/coops-mcp", "python", "-m", "coops_mcp"] }, "erddap": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/erddap-mcp", "python", "-m", "erddap_mcp"] }, "nhc": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/nhc-mcp", "python", "-m", "nhc_mcp"] }, "recon": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/recon-mcp", "python", "-m", "recon_mcp"] }, "stofs": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/stofs-mcp", "python", "-m", "stofs_mcp"] }, "ofs": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/ofs-mcp", "python", "-m", "ofs_mcp"] }, "rtofs": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/rtofs-mcp", "python", "-m", "rtofs_mcp"] }, "ww3": { "command": "uv", "args": ["run", "--directory", "/path/to/ocean-mcp/servers/ww3-mcp", "python", "-m", "ww3_mcp"] } } } ``` </details> ## Example Queries With servers configured, you can ask your AI assistant naturally: **CO-OPS queries:** - "Get current water levels at The Battery, NY" - "Find tide stations near Miami Beach" - "What are the flood statistics for Charleston, SC?" - "Show me the sea level trend at San Francisco" **ERDDAP queries:** - "Search for sea surface temperature datasets on CoastWatch" - "Get chlorophyll data off the California coast for January 2024" - "What ERDDAP servers cover the US East Coast?" - "List all glider datasets on IOOS Gliders ERDDAP" **NHC queries:** - "Are there any active tropical cyclones right now?" - "Show me Hurricane Katrina's track" - "Search for Category 5 hurricanes in the Atlantic" - "What is the forecast track for the active storm?" **Recon queries:** - "List HDOB reconnaissance flights for the 2024 Atlantic season" - "Get HDOB flight-level observations from October 7, 2024" - "Show me the Vortex Data Messages for Hurricane Milton" - "Get ATCF aircraft fix data for storm AL14 2024" **STOFS queries:** - "Get the STOFS water level forecast for The Battery, NY" - "Compare STOFS forecast vs observations at Boston for the past 24 hours" - "What are the top stations with highest predicted water levels?" - "Find STOFS stations within 50 km of New Orleans" **OFS queries:** - "What OFS models cover the Chesapeake Bay?" - "Get the water level forecast at lat 38.98, lon -76.48 from CBOFS" - "Compare CBOFS water level with CO-OPS observations at station 8571892" - "List available NGOFS2 forecast cycles for today" **RTOFS queries:** - "Get the RTOFS sea surface temperature forecast at 40°N, 74°W" - "Show me a temperature depth profile in the Gulf Stream" - "What RTOFS datasets are currently available on HYCOM THREDDS?" - "Get a vertical transect of salinity from Miami to Bermuda" - "Show the SST area forecast for the Gulf of Mexico" **WW3 queries:** - "What GFS-Wave model grids are available?" - "Find NDBC buoys near Cape Hatteras" - "Get the latest wave observations from buoy 41025" - "Show me the GFS-Wave forecast at 35°N, 75°W for the next 48 hours" - "Compare the wave forecast against buoy 41025 observations" **Cross-server queries:** - "Find CO-OPS stations near this ERDDAP buoy location" - "Compare tide station data with nearby ERDDAP satellite SST" - "Is there an active hurricane threatening the Gulf Coast?

See [docs/architecture.md](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](CONVENTIONS.md) for the full response/behavior contract (output caps, `retrieved_at`, error format, HTTP retries, dependency bounds). ## Citation If you use this project in your research or work, please cite: ```bibtex @software{jisan2025oceanmcp, author = {Jisan, Mansur Ali}, title = {Ocean MCP: Real-Time Marine Data, MCP-Native}, year = {2025}, url = {https://github.com/oceanmodeling/ocean-mcp}, note = {MCP servers for NOAA CO-OPS, ERDDAP, NHC, Recon, STOFS, OFS, RTOFS, WW3, NDBC, USGS, winds, GOES, ADCIRC, and SCHISM data} } ``` ## License Licensed under the MIT License.
