MCP Reference Servers

filesystem, git, fetch — the seven that survived the cull

free — MIT#the-baseline-local-capab

the floor every other server is measured against — and the repo whose archived half is the biggest source of dead install commands on the internet.

seven servers are still maintained by the protocol team: filesystem, git, fetch, memory, time, sequentialthinking and everything. filesystem alone does 471,000 npm downloads a week, second only to playwright.

filesystem does sandboxed read, write, edit, search and move inside directories you explicitly allow. git exposes status, diff, commit, log with timestamp filters, show and branch operations. fetch retrieves a url and converts it to markdown.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

the floor every other server is measured against — and the repo whose archived half is the biggest source of dead install commands on the internet.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
