# 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 2026-10-23).

Meta-router that searches and proxies 500+ MCP servers and A2A agent tools via a single 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-f1a15f96 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when an agent needs to discover which MCP servers or A2A tools exist for a given capability without knowing the specific tool in advance, or when you want a single safe proxy entry point with token compression and prompt-injection protection rather than connecting to 500+ individual servers directly.

## Known failure modes

- Query string too short or vague — returns no matching tools
- Queried endpoint URL is unreachable or returns non-200 — proxy error surfaced
- Prompt-Guard firewall blocks query if injection pattern detected
- Rate limit or payment failure — HTTP 402 returned requiring x402 payment
- No MCP servers indexed for the requested capability — empty result set

## 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 tools relevant to the query, including tool descriptions and connection details, with up to 85% token-compressed output and prompt-injection filtering applied. May also return the proxied response from a dispatched tool call if an endpoint URL is provided.
