# DeFi Token Due Diligence via A2A & MCP Tool Discovery Router

> DeFi Token Due Diligence via A2A & MCP Tool Discovery Router is a paid API for AI agents from github-audit.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches and routes across 500+ indexed MCP servers and A2A tools to perform DeFi token due diligence, with token-compressed results 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 github-audit-agentdiet-dev-defi-token-due-diligence-via-a2a-mcp-tool-fc183059
```

Example prompt: Search the tool discovery router for any available MCP servers or A2A tools that can do DeFi token due diligence on a contract address — I want on-chain risk scores and DEX intelligence.

## When to prefer this

Use this endpoint when an AI agent needs to discover and access DeFi token due diligence tools or any of 500+ MCP/A2A capabilities from a single connection, especially when token efficiency matters (85% compression) or when prompt injection safety is required. Prefer over direct MCP connections when you want a curated meta-router with built-in safety firewall.

## Known failure modes

- No matching tools found for the given query — returns empty or low-confidence results
- Query is too vague to match specific tools — suggest more specific capability keywords
- Upstream MCP server unavailable — partial results returned
- Payment not processed (HTTP 402) — requires x402 USDC micropayment
- Rate limiting if query volume exceeds plan thresholds

## 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://github-audit.agentdiet.dev/v1/workflows/defi-token-due-diligence)

## Output

Returns matched tools, endpoint references, and compressed capability metadata from the 500+ indexed MCP/A2A servers relevant to the query, potentially including DeFi token due diligence reports, risk scores, or routing recommendations — all filtered through a Prompt-Guard firewall to prevent injection attacks.
