NOAA WW3 MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for NOAA WW3 MCP Server?
NOAA WW3 MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package ww3-mcp was installed 45 times last week.
How do I connect NOAA WW3 MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls ww3-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use NOAA WW3 MCP Server?
The pypi package ww3-mcp was installed 45 times in the last week. Week over week that is -13%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is NOAA WW3 MCP Server open source?
Yes — it is published under the MIT licence, written in Python and 7 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
