## 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-code-release-security-gate-a2a-mcp-tool-cddbc1ee
```

Example prompt: Search the A2A and MCP tool index for something that can do GitHub security audits — I want to find the right tool to route my agent to without blowing up my token budget.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover and route to the right MCP server or A2A tool from a large index without managing individual connections, especially when token budget is a concern or when prompt-injection safety is required before connecting to external tools.

## Known failure modes

- Missing or empty query parameter returns validation error
- No matching tools found for the capability query
- Prompt-Guard firewall blocks a query that resembles prompt injection
- Upstream MCP index unavailable returns 503
- Payment not received (HTTP 402) if x402 micropayment not satisfied

## 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/code-release-security-gate)

## Output

Returns a token-compressed list of matching MCP servers or A2A tools from a 500+ entry index, including tool metadata, routing recommendations, and firewall clearance status, scoped to the capability query provided.
