Daily snapshots of the MCP Registry: first numbers

A developer at bot2botlabs has been taking daily snapshots of the official MCP Registry since 6 November 2026, publishing a baseline from the 7 November snapshot that counts 57,993 entries (57,090 active, 903 deprecated) from 36,027 publishers, with 91% listing exactly one server. Read-only tools/list probes of 550 public hosted servers found 388 answering openly and 123 requiring login, a median of 9 tools per server, and 31% of 6,621 listed tools carrying no annotations. The archive also found 34.7% of active entries give no source repository, 12% of 858 checked GitHub repos no longer exist, and the top 1% of 4,643 npm packages take about 90% of downloads.

The official MCP Registry https://registry.modelcontextprotocol.io 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 https://github.com/bot2botlabs/mcp-shelf-archive/releases/tag/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 and 903 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 lists 2,366 . 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: median 81 downloads/week; the top 1% take about 90% 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; initialize and tools/list only. - 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 mailto:jordan@bot2botlabs.com .
