The author has been taking daily full snapshots of the official MCP Registry (which keeps no history) since Nov 6, 2026, plus read-only tools/list probes of public hosted servers. Baseline findings:
- Scale: 57,993 entries (57,090 active, 903 deprecated), 36,027 publishers; 91% publish exactly one server; top ten publishers ≈15% of active entries, largest single account lists 2,366.
- Quality signals: 34.7% of active entries give no source repo; of 858 linked GitHub repos checked, 12% no longer exist and 55% of the rest have zero stars; median npm package gets just 81 downloads/week, with the top 1% taking 90% of downloads.
- Tool surface: 388 of 550 probed hosted servers answered openly; median 9 tools per server (max 165); 31% of 6,621 tools carry no readOnly/destructive annotations.
- Change rate: 158 added / 3 removed overnight; of 152 revisited servers, 16 changed tool definitions overnight — 14 from one publisher updating shared tools.
Method: initialize + tools/list only, no tool calls, no logins, no scraping; rotating samples, not exhaustive. Author-disclosed self-project, corrections welcome.
