# 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 across 500+ indexed MCP servers and A2A tools using a single query, 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-a4781c94
```

Example prompt: Search the agentdiet MCP tool index for any servers that handle SEC filings or company enrichment — I need to find the right tool to route my next workflow step through.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover the right MCP server or A2A tool at runtime without hardcoding integrations, especially when operating across many capability domains or when token budget is constrained. It is particularly useful for swarm architectures where a router agent needs to delegate to specialist tools selected from a large index.

## Known failure modes

- Query too vague returns low-relevance or empty results
- Indexed endpoint may be offline or deprecated since last crawl
- Token-compressed output may lose nuance for highly technical capability descriptions
- Payment failure via x402 prevents response
- Query string missing or empty 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://cve-intel.agentdiet.dev/v1/workflows)

## Output

Returns a list of matching MCP servers or A2A tools from the 500+ item index, with compressed capability descriptions, endpoint URLs, compatibility metadata, and safety status from the Prompt-Guard firewall. Responses use 85% token compression to minimize context usage.
