# DeFi Token Due Diligence Workflow (A2A & MCP Tool Discovery Router)

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

Searches a meta-index of 500+ MCP servers and A2A tools using a capability query, returning compressed, firewall-filtered results for DeFi token intelligence and agent tool discovery.

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 token-intel-agentdiet-dev-defi-token-due-diligence-workflow-a2a-mcp-2b4024b5
```

Example prompt: Search the agentdiet MCP and A2A tool index for capabilities related to 'DeFi token due diligence' and show me which tools are available, with compressed summaries.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability — especially in DeFi, token intelligence, or business-to-agent workflows — and when token efficiency (85% compression) and prompt injection safety are priorities. Prefer this over manually catalogued tool lists when the target capability space is broad or frequently updated.

## Known failure modes

- Missing or empty 'query' parameter returns a validation error
- Query matches no indexed tools, returning an empty or low-confidence result set
- Prompt-Guard firewall blocks or sanitizes results it flags as unsafe
- HTTP 402 payment required if x402 payment header not included
- Upstream MCP server index unavailable, causing timeout or partial results

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

## Output

Returns a list of matching MCP servers or A2A tool endpoints relevant to the query, with metadata summaries compressed to reduce token usage, filtered through a Prompt-Guard firewall to prevent prompt injection. Results include tool names, capability descriptions, and routing references.
