# Code Release Security Gate — A2A & MCP Tool Discovery Router

> Code Release Security Gate — A2A & MCP Tool Discovery Router is a paid API for AI agents from shopify-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Routes capability-search queries across 500+ indexed MCP servers and A2A tools with token compression and prompt-injection firewall, specifically surfacing the code-release-security-gate workflow endpoint.

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-code-release-security-gate-a2a-mcp-tool-a46c2210
```

Example prompt: Search the agentdiet MCP hub for any tools related to 'code release security gate' or GitHub security auditing and show me what endpoints are available with their capabilities.

## When to prefer this

Use this endpoint when you need to discover available MCP servers or A2A tools from a large indexed catalog via a single connection, especially when token efficiency matters (85% compression) or when you want prompt-injection protection built into the proxy layer. Prefer it over manual tool registries when routing an agent swarm across many tool providers.

## Known failure modes

- Empty or vague query returns no matching tools
- Query string too short (minLength:1 violated) returns 400 validation error
- Upstream MCP servers in the index may be offline, returning stale or unavailable entries
- Payment not fulfilled (HTTP 402) if x402 billing handshake fails
- Rate limiting or quota exceeded returns 429
- Malformed query may trigger prompt-guard firewall and be blocked

## 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 JSON object listing matching MCP server endpoints or A2A tool metadata that satisfy the capability query, potentially including compressed tool manifests, endpoint URLs, compliance flags, and prompt-guard status for each result.
