# 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 an index of 500+ MCP servers and A2A tools by capability query, returning compressed, firewall-screened tool metadata and routing results via 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-c1bdbb45
```

Example prompt: Search the MCP and A2A tool index for servers that handle 'company enrichment' — I want to find the best available tools and see their compressed metadata.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover MCP servers or A2A tools by capability without maintaining its own registry, or when routing through a safe proxy with built-in prompt injection protection and token compression is required. Prefer this over direct MCP connections when security screening and token efficiency are priorities.

## Known failure modes

- Empty or too-broad query returns no useful matches
- Endpoint URL verification fails if the URL is not indexed
- Generic queries like 'tools' may return overly broad result sets
- Service unavailable if the underlying index is down or rate-limited
- Payment failure (HTTP 402) if x402 payment is not properly attached

## 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/security-audit-dag)

## Output

Returns a structured object listing matched MCP servers and A2A tools for the query, including compressed capability metadata (up to 85% token reduction), Prompt-Guard firewall screening status, and routing information for connecting via the meta-router.
