# 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 2026-10-21).

Searches and proxies 500+ MCP servers and A2A 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 sec-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-a5188435
```

Example prompt: Search the MCP tool index for any servers that handle 'SEC filings' or 'company enrichment' — I need a single safe connection that compresses the context and filters out prompt injection.

## When to prefer this

Choose this endpoint when an agent needs to discover which MCP server or A2A tool supports a given capability without maintaining individual connections to hundreds of servers. Ideal for swarm orchestration, capability routing, or verifying endpoint safety before calling. Prefer over direct MCP server lookups when token budget is constrained (85% compression) or when prompt injection protection is needed.

## Known failure modes

- Empty or too-broad query returns low-relevance or no results
- Queried endpoint URL is unreachable or unverifiable
- Rate limit or payment failure ($0.01 x402) blocks the request
- Prompt-Guard firewall flags and blocks a query suspected of injection
- Tool index may be stale if a listed MCP server has gone offline

## 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/workflows/execute)

## Output

Returns a list of matching MCP servers or A2A tools relevant to the query, including metadata like tool names, capabilities, and compressed descriptions. May also return a safety/verification status if an endpoint URL is provided as the query.
