MCP Registry Health Index

A free, point-in-time health check of remote MCP servers listed in the official MCP Registry. Checked 2026-10-07 (19:52 UTC): 300 servers, one per distinct remote host, sampled at random from 17,274 hosts behind 25,432 remote servers (40,102 active registry entries in total).

Each server got exactly one initialize and one tools/list call over its listed transport, with no credentials, and a 8-second timeout. A server that requires sign-in is graded on whether it says so correctly (HTTP 401 with discoverable OAuth metadata earns full marks), not penalized for requiring auth.

Summary

Metric Value
Servers checked 300
Answered over HTTP 286 (95%)
Completed initialize without auth 164 (55%)
Listed tools without auth 164 (55%)
Require auth 95 (32%); with OAuth discovery: 82 (86%)
Median initialize latency 457 ms (p90 1038 ms)
Median tools per server 6.0 (2,556 tools in total)
Tools without a description 5 of 2,556 (0%)
Parameters without a description 666 of 7,975 (8%)
Tools with annotations 1,602 of 2,556 (63%)

Health grades: A 245 · B 13 · C 1 · D 0 · F 41

Tool metadata grades (servers whose tools we could list): A 146 · B 17 · C 0 · D 1 · F 0

What we saw

Why servers without auth didn't complete initialize: http 404/405 10, http 5xx 8, http 4xx 7, tls 6, dns 6, initialize error 2, timeout 2.

Protocol versions returned: 2025-06-18 139, 2024-11-05 13, 2025-03-26 10, 2025-11-25 2.

Transports that answered (including auth-required servers): streamable-http 259, sse 2.

Most common tool-metadata findings (share of servers whose tools we could list):

How grades work

Server owners: if your server's result looks wrong or you fixed something, ask for a re-check through support (app "Data tools / MCP Health Index", category "Question"; include the registry name). We'll re-run it and update this page; you can also ask us to leave your server out. To audit your own server in depth (tool descriptions, simulated tool-search rank among all registry servers, rewrite suggestions), see the Tool Listing Auditor ($0.50 per audit; this index is free).

Per-server results

Alphabetical by registry name. "Auth" is what the server asked for when called without credentials.
