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

Searches across 500+ indexed MCP servers and A2A tools by capability query, returning compressed, firewall-filtered tool matches via a single connection.

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 company-enrich-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-c2ab48da
```

Example prompt: Search the MCP and A2A tool index for any servers that support 'company enrichment' — I want to find which tools are available and route my agent to the best one.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to delegate a subtask to, especially when the agent doesn't have a hardcoded tool list. Particularly useful in swarm or orchestrator architectures where routing decisions must be made at runtime based on capability queries. Prefer this over manual tool registries when you need broad coverage (500+ servers), built-in token compression for context efficiency, and a Prompt-Guard firewall layer for safety.

## Known failure modes

- Query too vague — returns zero or low-quality matches
- Endpoint URL verification fails if target is offline or non-compliant
- Prompt-Guard firewall may block queries containing injection-like patterns
- No matching tools found for highly niche capability queries
- Service unavailable if payment (x402) is not properly handled

## 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://company-enrich.agentdiet.dev/v1/agent-router)

## Output

A compressed, firewall-screened list of matching MCP server entries or A2A tool records relevant to the capability query, or a verification result if an endpoint URL was submitted. Response uses 85% token compression to minimize context usage in agent pipelines.
