# Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router (B2B OSINT DAG)

> Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router (B2B OSINT DAG) is a paid API for AI agents from llms-generator.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches and routes across 500+ MCP servers and A2A agent tools via a single meta-router endpoint with token compression and prompt injection protection

## Facts

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 llms-generator-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-5eab589e
```

Example prompt: Search across all available MCP servers and A2A tools to find capabilities related to 'company enrichment' — I need to know which tools I can route to for B2B lead data.

## When to prefer this

Choose this endpoint when you need to discover or route to the right MCP server or A2A agent tool from a large index (500+) without managing individual server connections. It is especially useful when building multi-agent swarms, when you don't know which specific tool handles a capability, or when you need token-efficient tool manifests with built-in prompt injection protection. Prefer alternatives if you already know the exact MCP server URL and just need to call it directly.

## Known failure modes

- Empty query string returns a 400 validation error
- No matching tools found for obscure or misspelled capability queries
- Upstream MCP servers temporarily unavailable causing partial result sets
- Rate limiting or payment failure via x402 if $0.01 micropayment not honored
- Query too broad returns unranked or noisy tool list

## 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://llms-generator.agentdiet.dev/v1/b2b-osint-dag)

## Output

Returns a list of matching MCP servers and A2A tool endpoints relevant to the query, with compressed capability metadata (85% token reduction), tool descriptions, routing information, and Prompt-Guard firewall screening applied to prevent prompt injection from upstream tools.
