How we keep this index honest.
Where entries come from
The official MCP registry API, synced nightly — plus manual submissions, reviewed by hand. No scraping, no imports from other directories.
What “verified” means
Every night we check each entry's repository and package: does the repo exist, is it archived, when was the last commit or release, is the npm package alive and how often is it downloaded. An entry silent for six months is stamped STALE. An entry whose repo is gone or archived is stamped DEAD and demoted out of listings. Everything else carries a dated VERIFIED stamp — the date is when we actually checked, not when someone last edited a wiki.
How curation works
Entries start as synced-only: real data, no judgment. Curated entries add a hand-written review, a capability matrix, setup gotchas, and honest alternatives. Reviews are dated and re-checked — a review older than the server's last release gets revisited.
What “flagged” means
Some listings game directories: bot-farmed star counts, entries that borrow a famous repo's stars while linking to unrelated code, namespace squats impersonating official vendors, READMEs with hidden instructions aimed at AI agents, or install configs that ask for wallet private keys. When our editors find those signals, the entry is flagged: it ranks last, is never featured, and carries a warning on its page. We keep it listed rather than deleting it, so you can see what we found.
What “delisted” means
The official registry contains a few entries that are templates or placeholders — published as examples, not servers anyone can use — plus superseded duplicates: the same package re-registered under a new name, leaving the old listing frozen. Neither is bad faith, so we don't flag them; we delist them. A delisted entry is excluded from browsing, search, and category pages, but its page stays reachable and says why (and, for duplicates, points at the current listing).
What “featured” means
Featured placements are paid. They're always labeled, they don't affect reviews or flags, and a stale featured server gets flagged like everyone else.
