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-4cdb3e4c
```

Example prompt: Search the MCP tool index for any servers that handle SEC filings or company enrichment — I want to find which tools are available and route my query through the safest one.

## When to prefer this

Use this endpoint when an AI agent needs to discover or route to one of hundreds of MCP servers or A2A tools without maintaining separate connections to each. Ideal when token efficiency matters (85% compression), when you want a single entry point for multi-tool orchestration, or when prompt injection safety is a concern. Prefer over direct MCP calls when the target capability is unknown and needs to be discovered dynamically.

## Known failure modes

- No matching tools found for the query — returns empty result set
- Query too vague — endpoint may return low-relevance or excessive results
- Prompt-Guard firewall blocks query if it appears to contain injection patterns
- Downstream MCP server unavailable — routing may fail with upstream error
- Malformed or unresolvable endpoint URL when used in verification mode

## 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/execute)

## Output

Returns a list of matching MCP servers or A2A tools that satisfy the capability query, including tool metadata, relevance ranking, and routing information. Responses are token-compressed (up to 85%) and filtered through a Prompt-Guard firewall to remove injection risks.
