## 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 company-enrich-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-9360115a
```

Example prompt: Search across all available MCP servers and A2A tools for anything that can do company enrichment or B2B lead data — I want to find the best tool in the index for that capability.

## When to prefer this

Choose this endpoint when you need to discover or route to MCP servers or A2A tools at scale without maintaining individual connections to each provider. It is especially valuable when you don't know which specific MCP server handles a capability, when you want token-efficient tool discovery (85% compression vs raw listings), or when you need prompt injection protection built into the discovery layer.

## Known failure modes

- Empty or overly broad query returns too many low-relevance results
- Query for a very niche capability returns no matches if not indexed
- Endpoint URL verification fails if the target is offline or non-compliant
- Rate limiting or payment failure (HTTP 402) if x402 credentials are missing or exhausted
- Timeout if the underlying MCP server index is slow to respond

## 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://company-enrich.agentdiet.dev/v1/workflows/execute)

## Output

Returns a list of matching MCP servers or A2A tools relevant to the search query, with token-compressed capability descriptions, endpoint URLs, and routing metadata. Results are filtered through a Prompt-Guard firewall to prevent injection attacks.
