How to read ratings & labels
On this site, some skills show an AI impact score based on documentation; servers do not show one. This page explains the scoring scale, its limits, and the cost and access labels.
⌁ Impact
Impact rating (1–5)
The impact score is an AI judgment of how useful a tool appears from its documentation. The scoring instructions tell the AI not to raise a score because of GitHub stars.
- 5 — transformative and broadly useful; foundational infrastructure or best-in-class at a major task
- 4 — very useful with solid scope
- 3 — useful in its niche
- 2 — narrow, duplicative, or only useful inside one project's own workflow
- 1 — trivial, demo, or template
In the July 5, 2026 scoring, an AI read entry details and short documentation excerpts; nothing was installed or run. Those scores have not been updated since. Some skills have no score, including entries added after that date.
An impact score does not establish a tool's quality, safety, or security, or show that it works.
⌁ Tool counts
Tool counts from connections
On some server pages, the Tools line says “counted once with only startup setup”. Each count came from one connection to that server between August 11 and October 5, 2026, with only the setup needed to start it. Tools requiring additional settings, modes or optional credentials were not counted. These counts are separate from the AI impact score shown for some skills.
⌁ Cost & access
Cost & access labels
- Listed as free — the tool is listed as free to use; a service it connects to may still require an account or charge fees.
- Free option — the provider says it offers a free trial, a free tier or free credits.
- Access details — the instructions list variables named for keys or credentials, or mention a free plan, quota or credits. Check the provider's access requirements.
- Payment mentioned — the instructions mention pricing or payment and list variables named for keys or credentials. Check the provider's pricing for actual costs.
“Listed as free” (shown as “Free” on catalog cards) does not establish that a tool is open source. Some entries have no cost label.
On skill pages, specific setup requirements appear under Before you install. A License tab appears when license information is available.
⌁ Changes
Documentation can change
Projects can move or disappear, and documentation can change after a score is assigned. An impact score reflects the documentation used for scoring; it does not show whether the current documentation or links are up to date.
