# Why MCP servers need a census

Directories scale discovery. Trust needs continuous evidence.

## Discovery exploded
MCP server counts move quickly. Stars and SEO lists cannot keep up with ownership and health.

## Registries disclaim vetting
That is honest — and it leaves a gap. Someone has to re-check public facts daily.

## What continuous evidence looks like
Harvest → enrich → probe → cite → score → expose via UI and API. Publish limits. Refuse to invent Official.

## Use the census that way
[Coverage](/coverage) for totals · [lookup](/lookup) for a name · [Learn](/learn) for vocabulary.
