The MCP Index makes a saved official-registry snapshot searchable. Entries are ordered by recorded registry update date. The catalog does not measure adoption, independently test servers or establish that every entry is open source.
A searchable saved snapshot of server records from the official Model Context Protocol registry. A listing is not a safety, quality, open-source-license or availability certification.
Entries are ordered by the recorded registry update timestamp, newest first. Freshness categories summarize that timestamp; they are not GitHub popularity, adoption or runtime-health measurements.
The saved snapshot date is shown with the catalog. The snapshot is built only after the official latest-version cursor traversal completes. Deleted records are excluded from search and retained historical URLs are labeled. A moving registry is not an atomic census; listings are not independently tested.
