## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability foomworks-mcp-registry-snapshot-feed-37ef080f
```

Example prompt: Can you pull the latest MCP registry snapshot so I can see all the currently registered, deduplicated, quality-scored MCP servers and capabilities?

## When to prefer this

Use this endpoint when you need a comprehensive, pre-deduplicated, and quality-scored view of the MCP registry in a single call, rather than assembling registry data from multiple raw sources yourself. Ideal for agents bootstrapping their tool-discovery layer or periodically syncing available MCP capabilities.

## Known failure modes

- Payment required (402) if x402 payment of $0.005 USDC is not included
- Stale data if snapshot has not refreshed within the 30-minute window
- Empty or partial registry if upstream registry sources are unavailable
- Timeout if the Cloudflare Worker is under load

## How this service works

Full MCP registry snapshot: deduped, quality-scored, refreshed every 30 minutes.

## Output

A full snapshot of the MCP registry containing deduplicated entries with quality scores, representing the current state of all registered MCP capabilities as of the most recent 30-minute refresh cycle.
