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

Searches and routes queries across 500+ indexed MCP servers and A2A tools 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 token-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-8d5cc887
```

Example prompt: Search your MCP and A2A tool index for anything that handles SEC filings retrieval and route me to the best matching endpoint.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool handles a given capability without hardcoding individual endpoints, especially when operating across a diverse swarm of 500+ tools and needing token-efficient, firewall-protected routing in a single connection.

## Known failure modes

- No matching tools found for obscure or unsupported capability query
- Token compression or proxy layer times out for slow upstream MCP servers
- Prompt-Guard firewall blocks a query flagged as injection attempt
- Upstream A2A or MCP endpoint is offline or non-compliant
- Malformed or empty query string returns validation error

## 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://token-intel.agentdiet.dev/v1/bundle-execute)

## Output

A bundle of matching MCP server or A2A tool metadata, ranked by relevance to the query, with token-compressed responses and prompt-injection-filtered results indicating which endpoints are available and how to invoke them.
