# 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 discovers capabilities across 500+ MCP servers and A2A tools using a single meta-router connection with token compression and prompt-guard safety.

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-0e249a97
```

Example prompt: Search the meta-router for MCP tools that can do 'company enrichment' — I need to find indexed tools or A2A endpoints that handle B2B lead data.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover which tools or MCP servers are available for a given capability without pre-configuring each connection individually. It is especially valuable when you want a single entry point to 500+ indexed tools, need Prompt-Guard firewall safety checks on external endpoints, or want 85% token-compressed tool metadata to minimize context usage during multi-agent orchestration.

## Known failure modes

- Empty query string returns a 400 validation error
- No matching tools found returns an empty result set
- Endpoint URL verification may return unknown status for unindexed endpoints
- Token-compressed results may lose edge-case capability descriptions
- Rate limiting or payment required (HTTP 402) if per-call credit is exhausted

## 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/b2b-lead-enrichment)

## Output

Returns a list of matching MCP servers or A2A tools ranked by relevance to the query, with compressed metadata about each tool's capabilities, endpoint URLs, and safety status from the Prompt-Guard firewall.
