## 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 forest-gas-station-mcp-registry-discovery-813ec71f -d '<json body>'
```

Example prompt: Search the MCP registry for public server candidates related to 'weather forecasting' and return up to 10 results.

## When to prefer this

Use this endpoint when an agent needs to dynamically discover available MCP servers or tools by keyword, browse a registry for candidates, or programmatically enumerate what AI-callable services are publicly registered. Prefer this over static configuration when the set of available MCP servers is unknown or frequently changing.

## Known failure modes

- Query exceeds 256 characters — request rejected
- Limit outside 1–20 range — validation error
- Registry URL unreachable or invalid — connection or parsing error
- No matching servers found — empty result set returned
- Registry returns malformed metadata — partial or empty response
