The official MCP Registry shows what’s listed now, but it doesn’t keep a history. Since 6 November 2026 I’ve been taking a full snapshot every day, plus read-only tools/list probes of public hosted servers (initialize + list tools only — never calling a tool). This is a baseline from the 7 November 2026, 06:36 UTC snapshot (mcp-shelf-archive snapshot-2026-11-07). Two days of history so far, so nothing here is a trend yet.
What’s on the shelf
57,993 entries:57,090 active and903 deprecated.
- Overnight from 6→7 November: 158 added,3 removed.
19,109 active entries have a latest-version date in October 2026;9,295 more are dated 1–7 November (that’s the date of each entry’s latest version, not when it was first listed).
Who publishes
36,027 publishers. #
91% list exactly one server.
- Ten publishers account for about 15% of active entries; the single largest GitHub-namespaced account lists2,366 .
Source links and downloads
34.7% of active entries give no source repository.
- Of 858 linked GitHub repositories checked,104 (12%) no longer exist;55% of the rest have zero stars.
- Across 4,643 servers whose npm packages we checked: median81 downloads/week; the top1% take about90% of all downloads in that sample.
Tool lists (hosted, public HTTPS only)
- Asked 550 hosted servers;388 answered openly;123 required a login.
- Median server exposes 9 tools; the largest in the sample,165 .
- Of 6,621 tools listed,31% carry no annotations at all (no readOnly / destructive hints).
- Of 152 servers already seen the day before,16 changed tool definitions overnight —14 of those 16 were one publisher updating the same shared tools across its servers. Read that as one night’s data, not a rate.
Method (short)
- Registry: public MCP Registry API, latest version of every entry, daily.
- Tool lists: public, no-login, HTTPS endpoints; rotating sample + fixed watch list;
initializeandtools/listonly. - Downloads / repos: official npm and GitHub APIs, daily rotating samples.
- No logins, no scraping, no tool calls.
Limits
Samples rotate and aren’t the whole shelf. Counting entries isn’t judging quality. Corrections welcome: jordan@bot2botlabs.com.
