# 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+ MCP servers and A2A tools via a single meta-router endpoint 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-932afabb
```

Example prompt: Search the MCP and A2A tool registry for any servers that handle 'github security auditing' — find me the best matching tools with compressed results.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover MCP servers or A2A tools at runtime without hardcoding specific integrations, especially when token budget is constrained (85% compression) or when prompt injection safety is a concern. Prefer this over direct MCP server calls when you don't know which tool to use and need to search across 500+ indexed servers.

## Known failure modes

- Query string missing or empty — returns 400 error
- No matching tools found for query — returns empty results list
- Endpoint URL provided is unreachable or not a valid MCP server
- Payment not processed (x402 flow fails) — endpoint returns 402
- Rate limiting if too many requests in short succession

## 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/execute)

## Output

Returns a list of matching MCP servers or A2A tools relevant to the query, with metadata about each tool's capabilities, delivered with 85% token compression through a Prompt-Guard firewall that filters malicious prompt injection.
