# 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 2026-10-23).

Searches and routes to 500+ MCP servers and A2A tools via a single meta-router endpoint with token compression and prompt-injection firewall

## 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 sec-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-ee8d0753 -d '<json body>'
```

Example prompt: Search the MCP tool broker for any available tools that handle 'company lead enrichment' — I want to find the right capability to plug into my agent pipeline.

## When to prefer this

Choose this endpoint when you need to dynamically discover which MCP server or A2A tool handles a given capability, rather than hardcoding tool URLs. Ideal for building agent swarms that need to self-configure, for orchestrators that must route tasks to the right specialist tool, or when you want a single connection point to 500+ tools with built-in safety filtering and token compression.

## Known failure modes

- Empty or vague query returns no meaningful matches
- Query string too short (minLength:1 not met) returns validation error
- No matching tools found for a highly specific or novel capability
- Service unavailable if meta-index is being updated
- Payment required (HTTP 402) if x402 micropayment header is missing or invalid
- Timeout if downstream tool verification takes too long

## 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/tool-broker)

## Output

Returns a list of matching MCP servers or A2A tools relevant to the query, with endpoint metadata, capability descriptions, and token-compressed summaries. May include routing instructions, tool schemas, and safety ratings from the integrated Prompt-Guard firewall.
