Since <strong>6 November 2026</strong> I’ve been taking a full snapshot every day, plus read-only <code>tools/list</code> probes of public hosted servers (initialize + list tools only — never calling a tool). This is a baseline from the <strong>7 November 2026, 06:36 UTC</strong> snapshot (<a href="https://github.com/bot2botlabs/mcp-shelf-archive/releases/tag/snapshot-2026-11-07" rel="noopener noreferrer">mcp-shelf-archive <code>snapshot-2026-11-07</code></a>). Two days of history so far, so nothing here is a trend yet.</p> <h3> What’s on the shelf </h3> <ul> <li> <strong>57,993</strong> entries: <strong>57,090</strong> active and <strong>903</strong> deprecated.</li> <li>Overnight from 6→7 November: <strong>158</strong> added, <strong>3</strong> removed.</li> <li> <strong>19,109</strong> active entries have a latest-version date in October 2026; <strong>9,295</strong> more are dated 1–7 November (that’s the date of each entry’s latest version, not when it was first listed).</li> </ul> <h3> Who publishes </h3> <ul> <li> <strong>36,027</strong> publishers.</li> <li> <strong>91%</strong> list exactly one server.</li> <li>Ten publishers account for about <strong>15%</strong> of active entries; the single largest GitHub-namespaced account lists <strong>2,366</strong>.</li> </ul> <h3> Source links and downloads </h3> <ul> <li> <strong>34.7%</strong> of active entries give no source repository.</li> <li>Of <strong>858</strong> linked GitHub repositories checked, <strong>104 (12%)</strong> no longer exist; <strong>55%</strong> of the rest have zero stars.</li> <li>Across <strong>4,643</strong> servers whose npm packages we checked: median <strong>81</strong> downloads/week; the top <strong>1%</strong> take about <strong>90%</strong> of all downloads in that sample.</li> </ul> <h3> Tool lists (hosted, public HTTPS only) </h3> <ul> <li>Asked <strong>550</strong> hosted servers; <strong>388</strong> answered openly; <strong>123</strong> required a login.</li> <li>Median server exposes <strong>9</strong> tools; the largest in the sample, <strong>165</strong>.</li> <li>Of <strong>6,621</strong> tools listed, <strong>31%</strong> carry no annotations at all (no readOnly / destructive hints).</li> <li>Of <strong>152</strong> servers already seen the day before, <strong>16</strong> changed tool definitions overnight — <strong>14</strong> of those 16 were one publisher updating the same shared tools across its servers. Read that as one night’s data, not a rate.</li> </ul> <h3> Method (short) </h3> <ul> <li>Registry: public MCP Registry API, latest version of every entry, daily.</li> <li>Tool lists: public, no-login, HTTPS endpoints; rotating sample + fixed watch list; <code>initialize</code> and <code>tools/list</code> only.</li> <li>Downloads / repos: official npm and GitHub APIs, daily rotating samples.</li> <li>No logins, no scraping, no tool calls.</li> </ul> <h3> Limits </h3> <p>Samples rotate and aren’t the whole shelf. Counting entries isn’t judging quality.
