How NOAA WW3 MCP Server compares

Against every graded MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 94/100; higher than 96% of 48,255 servers
Tools: 9; the typical server has 7
Tools that change things: 0%; typical: 0%. Fewer write tools means less an agent can break
GitHub stars: 9; more than 87% of 28,688 servers

What the publisher says

From the NOAA WW3 MCP Server repository's README, as published. We do not edit it. Read it on GitHub

OceanMCP

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

Servers

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).

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
