Most MCP servers are still demoware

Influzer’s registry has ~6,000 MCP servers — and only about 7% with indexed tools. Here is the 30-second filter before you install another one.

Directory scale is no longer the story. Quality is. Influzer indexes around ~6,000 MCP servers; after daily validation, only about ~7% show indexed tools — and far fewer look ready for a shared agent stack.

30-second filter (skip on any hard fail):

Transport — labeled stdio or HTTPS remote that matches your client lane
Tools — real tools/list verbs for one clear job (not hello/echo)
Auth — revoke path (env / OAuth / IdP) — not a personal PAT in git
Docs — a second engineer can install without Slack archaeology

Why it matters: agents call capabilities, not GitHub stars. README theater wastes weeks and creates shadow tool access. Start from the Top 100, shortlist with Discovery, then read the full playbook: Most MCP servers are still demoware.
