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

## 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 sec-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-22b58927
```

Example prompt: Search the MCP and A2A tool registry for any servers that can do GitHub security auditing or code scanning — I want to find the best available capability for reviewing a repo.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover new tools or MCP servers at runtime without hardcoding integrations, especially when the agent's required capability is unknown in advance. Ideal for swarm architectures where sub-agents need to self-select appropriate tools, or when verifying whether a known URL is a valid A2A/MCP endpoint.

## Known failure modes

- Empty query string returns validation error
- No matching tools found for niche or misspelled query
- Endpoint URL verification returns non-compliant or unreachable status
- Token compression may omit edge-case metadata fields
- Firewall may flag legitimate but unusual tool descriptions as suspicious

## 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/agent-router)

## Output

Returns a token-compressed listing of matching MCP servers or A2A tools relevant to the query, including capability descriptions, endpoint URLs, and firewall-cleared safety signals — all condensed for efficient agent consumption.
