Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

Signal	Value	What it measures	Window	Observed	Source
GitHub stars	9	Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality.	cumulative, all time	2026-08-06	GitHub
Last commit	2026-07-30	Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained.	point in time	2026-08-06	GitHub
Open issues	3	Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one.	as of fetch	2026-08-06	GitHub
Latest published version	0.6.0	Latest version string the maintainer published to the registry.	as of fetch	2026-07-28	Model Context Protocol
Registry record last updated	2026-07-28	When the registry record was last updated by its maintainer.	point in time	2026-07-28	Model Context Protocol
License	Apache-2.0	Licence GitHub detected in the repository. Detection can be wrong; the LICENSE file is authoritative.	as of fetch	2026-08-06	GitHub
First listed in the MCP Registry	2026-07-28	Date this server was first published to the official MCP Registry. Not a usage or quality measure.	point in time	2026-07-28	Model Context Protocol
repository status	active	The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on.	as of fetch	2026-08-06	GitHub

These share tags the maintainers applied themselves, such as cheminformatics, chemistry, scientific-computing, cyanheads. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
