# 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 2026-10-23).

Searches and routes across 500+ indexed MCP servers and A2A tools using a single connection with token compression and prompt-injection 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 company-enrich-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-23a29dba -d '<json body>'
```

Example prompt: Search the MCP and A2A tool catalog for any available servers or agents that can handle 'company enrichment' — I need to find the right tool for extracting B2B contact and tech stack data.

## When to prefer this

Choose this endpoint when an agent needs to dynamically discover or route to the right MCP server or A2A tool from a large index, rather than hardcoding a single tool. Ideal for orchestration layers, swarm agents, or any workflow where the correct downstream tool is not known in advance. Prefer this over manually maintained tool lists when you need coverage across 500+ servers with built-in security filtering.

## Known failure modes

- Empty query string returns validation error (minLength: 1)
- No matching tools found for obscure or misspelled capability query — returns empty results
- Endpoint URL verification fails if the URL is unreachable or not indexed
- Prompt-Guard firewall may flag and block queries containing suspicious injection patterns
- Service unavailable if 500+ upstream MCP servers are unresponsive

## 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/broker/catalog)

## Output

Returns a filtered catalog of matching MCP servers and A2A tools, including their capabilities, endpoint URLs, and metadata — compressed to reduce token usage — along with any prompt-injection risk flags from the Prompt-Guard firewall.
