# 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 capability query, returning compressed, prompt-injection-safe results for agent orchestration.

## Facts

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-bfae3069 -d '<json body>'
```

Example prompt: Search the MCP and A2A tool index for any servers or agents that can handle 'SEC filings' or 'company enrichment' — I want to find the right tool to route my agent to.

## When to prefer this

Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool handles a given capability at runtime, rather than hard-coding tool selections. Especially useful in swarm orchestration scenarios where the best tool for a task is unknown ahead of time, or when you need to proxy calls through a safety firewall before invoking third-party MCP endpoints.

## Known failure modes

- Empty or vague query returns no useful matches
- Unknown endpoint URL cannot be verified or is not in the index
- Rate limiting or payment failure (x402) blocks the request
- Prompt-Guard firewall rejects a query flagged as potentially malicious
- Schema validation error if query field is missing or empty

## 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 compressed, token-efficient list of matching MCP servers and A2A tools relevant to the capability query, including endpoint metadata, routing information, and prompt-injection safety status. Results pass through a Prompt-Guard firewall to filter malicious payloads.
