Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 shopify-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-ec136ac0 -d '<json body>'
```

Example prompt: Search across all available MCP servers and A2A tools to find me the best capability for 'company enrichment' — I want the top matches with token-compressed results and prompt injection protection.

## When to prefer this

Choose this endpoint when you need to discover which of hundreds of MCP servers or A2A tools best handles a given capability, especially when you want a single connection point, token-efficient responses, and built-in prompt-injection protection rather than querying multiple registries manually.

## Known failure modes

- Empty or too-vague query string returns no relevant matches
- Unknown or malformed endpoint URL fails verification check
- Prompt-Guard firewall blocks a legitimate but unusual query
- Downstream MCP server unavailable causes routing failure
- Rate limit or payment failure (HTTP 402) if USDC balance is insufficient

## How this service works

Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-intel.agentdiet.dev/v1/workflows/execute)

## Output

Returns a filtered, token-compressed list of matching MCP servers or A2A tools ranked by relevance to the query, including endpoint details and capability summaries, all screened through the Prompt-Guard firewall to remove injected content.
