# ScytheRadar MCP

On-chain risk intelligence for AI agents — **read-only**, **bilingual (中文/English)**, and built for the Chinese-speaking agent ecosystem first. Screen wallets, check blacklists, and trace fund flows, with rug-pull forensics no other crypto MCP ships.

**Read-only by design.** No private keys, no signing, no transaction execution. The worst case is a wrong answer; your funds are never at risk.

## Why ScytheRadar (vs the 15+ crypto-AML MCPs)

| We win where they don't | The gap we fill |
|---|---|
| 🀄 Chinese agent ecosystem first | First mover for Coze / Dify / Chinese Claude & Cursor users — bilingual tool descriptions and docs. Every competitor is English-only. |
| 🪦 Rug-pull forensics (death files) | 87+ rug-pull case files with autopsy reports, timelines, and scam-contract code breakdowns — not just a score, a case file. |
| 💧 TRON 脏U (dirty-USDT) focus | Tether's official freeze list (9,000+ addresses) + OFAC multi-chain sanctions — built for Asia's P2P/OTC "should I accept this USDT" reality. |
| 💰 Cheap, read-only, keyless trial | 6 free calls/day, no signup; paid plans from a few USDT. Built for retail users and small merchants, not banks. |

## Tools

| Tool | What it does |
|---|---|
| `screen_address` | Risk-screen a wallet address (0-100 score / level / verdict / risk flags) |
| `check_blacklist` | Blacklist hit check (Tether freezes / OFAC sanctions / phishing) |
| `trace_funds` | Fund tracing (flow / hops / aggregation / suspected laundering path) |

## Language

Tool descriptions are bilingual (中文 / English), so Chinese-language agents (Coze, Dify, 文心, Kimi) call the right tool just as reliably as English ones. 工具描述中英双语，中文 agent 同样能精准调用。
