# Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router

> Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm 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).

Searches and routes queries across 500+ indexed MCP servers and A2A tools via a single connection, with token compression and prompt firewall protection.

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-44e01288
```

Example prompt: Search the swarm router for any indexed MCP servers or A2A tools that handle SEC filings and company enrichment — I want to know what's available through a single connection.

## When to prefer this

Choose this endpoint when you need to discover or route to multiple MCP servers or A2A tools without managing individual connections, especially when token efficiency matters or when you want a firewall layer between your agent and external tool calls. Not suitable for direct execution of tasks — use it to find and route to the right tool, not to perform the tool's function itself.

## Known failure modes

- Missing or empty query parameter returns validation error
- No matching tools found for obscure or unsupported capability queries
- Upstream MCP servers may be temporarily unavailable causing partial results
- Overly broad queries may return too many results to be useful
- Payment via x402 may fail 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/swarm-router)

## Output

Returns a structured list of matching MCP servers or A2A tool endpoints from the 500+ indexed catalog, including capability metadata relevant to the query, with token-compressed responses passed through the Prompt-Guard firewall.
