What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

Paste this line into a README of your own. The badge states how many values the registry holds for the entry and when it last looked, and it links back to this page.

[![tracevero: number of measured values and date of collection for this registry entry](https://tracevero.com/badge/mcp/io-github-alex-feel-mcp-context-server.svg)](https://tracevero.com/mcp/io-github-alex-feel-mcp-context-server)

The image is drawn again on every request, so it always reports the current state while the pasted line stays as it is. It carries no rating and no traffic light – only the two measured figures.
