# 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 across 500+ indexed MCP servers and A2A tools via a single meta-router connection with prompt-guard firewall and token compression

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-def3f992
```

Example prompt: Search the MCP tool index for any servers that handle 'company enrichment' or 'B2B lead data' — I want to find the best tool I can route through for that capability.

## When to prefer this

Choose this endpoint when you need to discover which MCP servers or A2A tools are available for a given capability across a broad index of 500+ options, rather than calling a known specific tool directly. It is especially useful when building agent pipelines that need dynamic tool selection, when you want a single safe-proxy entry point with prompt firewall protection, or when you need to verify whether a particular endpoint URL is compliant and reachable.

## Known failure modes

- Empty or vague query returns no meaningful matches
- Query for a niche capability with no indexed tools returns empty result set
- Endpoint URL verification queries may time out if the remote server is unreachable
- Rate limiting or payment failure via x402 returns HTTP 402 with payment required
- Malformed query string may return a generic error response

## 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/mesh/dispatch)

## Output

Returns a list of matching MCP servers or A2A tools from the 500+ indexed registry, including endpoint metadata, capability descriptions, and routing information relevant to the query, with token-compressed responses and prompt-guard filtered output.
