# 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 company-enrich.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning token-compressed results through a prompt-guard firewall

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 company-enrich-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-6a0472a3
```

Example prompt: Search the MCP and A2A tool index for anything that can do company enrichment or B2B lead data — I want to see what's available with token-compressed results.

## When to prefer this

Use this endpoint when you need to discover which MCP server or A2A tool provides a specific capability across a large ecosystem index, rather than knowing the tool's URL in advance. Prefer this over manual tool registries when you want token-efficient results and built-in prompt safety filtering.

## Known failure modes

- Empty or vague query returns no useful matches
- Query too broad returns overwhelming number of results
- Indexed tool is stale or its endpoint is no longer live
- Prompt-Guard firewall blocks a legitimate query as suspicious
- x402 payment failure prevents access to results

## 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://company-enrich.agentdiet.dev/v1/bundle-execute)

## Output

A token-compressed list of matching MCP servers or A2A tools from a 500+ entry index, filtered by the capability query, with endpoint metadata and routing information passed through a Prompt-Guard firewall for safety.
