# 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 agent tools by capability query, returning compressed, safe-proxied routing results through a single connection

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-4aa41d5b
```

Example prompt: Search the MCP and A2A tool index for agents that handle 'SEC filings' — I want to find the best available endpoint I can route through for that capability.

## When to prefer this

Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. Ideal for orchestration layers, swarm routers, or meta-agents that need to find the right downstream tool at runtime. Best when you want a single aggregated index rather than querying individual tool registries.

## Known failure modes

- Empty query string returns validation error
- No matching tools found for obscure or highly specific capability queries
- Firewall blocks queries flagged as prompt injection attempts
- Downstream MCP server index may be stale or partially unavailable
- Rate limiting or payment failure via x402 returns 402 status

## 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/universal-mcp-gateway)

## Output

A filtered, token-compressed list of matching MCP server or A2A tool records from the 500+ endpoint index, including capability descriptors, routing metadata, and Prompt-Guard firewall-screened summaries relevant to the input query.
