# 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 cve-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 via a single meta-router connection with token compression and prompt injection firewall.

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 cve-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-79918791
```

Example prompt: Search the MCP tool index for any servers that handle 'SEC filings' or 'company enrichment' — I need to find and route to the best available tool for pulling financial data on a public company.

## When to prefer this

Choose this endpoint when an agent needs to dynamically discover and route to specialized MCP servers or A2A tools without maintaining its own registry. Particularly useful when the required capability (e.g. on-chain risk, SEC filings, domain OSINT) is not known ahead of time, or when you want a single connection point with safety filtering rather than calling dozens of external tool registries directly.

## Known failure modes

- No matching tools found for the given query — returns empty result set
- Query string too vague — returns overly broad or irrelevant tool matches
- Indexed tool is offline or non-responsive at routing time
- Payment required error (HTTP 402) if x402 payment header not included
- Rate limiting or quota exhaustion after repeated calls
- Prompt injection attempt blocked by Prompt-Guard firewall returning 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://cve-intel.agentdiet.dev/v1/mesh/dispatch)

## Output

Returns a list of matching MCP servers or A2A tool endpoints relevant to the capability query, with compressed tool manifests (85% token reduction claimed), routing metadata, and safety-screened results from the Prompt-Guard firewall layer.
