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

Searches and routes to 500+ indexed MCP servers and A2A tools via a single meta-router connection with token compression and prompt 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 sec-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-3f4d8827
```

Example prompt: Search the A2A mesh for any MCP servers or tools that handle SEC filings and company enrichment — I want to find safe, proxied options I can route my agent to.

## When to prefer this

Choose this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, rather than hardcoding tool URLs. Especially useful for swarm routing, safe proxying through a prompt-guard firewall, or when you want a single connection point to 500+ indexed tools with token-compressed responses.

## Known failure modes

- Empty query returns validation error
- No matching tools found for obscure capability query
- Endpoint URL verification returns unknown or unindexed result
- Payment not processed (x402 required at $0.01 per call)
- Firewall blocks malicious or injection-laden queries

## 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://sec-intel.agentdiet.dev/v1/a2a-mesh)

## Output

Returns a list of matching MCP servers or A2A tools for the given capability query, including tool metadata, routing details, and safety/firewall status, compressed with 85% token efficiency
