# 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 across 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-704db31c
```

Example prompt: Search the MCP and A2A tool index for any servers or agents that can handle 'company enrichment' — I need to find the best available tool for that capability and route my request through it safely.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover the right tool or MCP server from a large index without managing multiple connections, or when you want a single safe-proxy routing layer with built-in token compression and prompt injection protection. Ideal for orchestrating multi-agent swarms where tool selection needs to happen at runtime.

## Known failure modes

- Empty or vague query returns low-relevance or no matches
- Endpoint URL verification may fail if the URL is unreachable or not indexed
- Token compression may reduce fidelity of returned capability descriptions
- Rate limiting or payment failures due to x402 micropayment issues
- Prompt-Guard firewall may reject queries flagged as adversarial

## 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/workflows)

## Output

Returns a list of matched MCP servers or A2A tools relevant to the query, with metadata including tool names, capabilities, compressed descriptions, and routing information. When used for URL verification, returns safety and legitimacy signals about the endpoint.
