TRON USDT Risk Checker

tron-usdt-mcp

MCP server for TRON USDT (TRC20) address risk. It checks whether Tether has blacklisted (frozen) an address, screens it against sanctions lists and abuse reports, and builds a full AML report.

This package is a small stdio proxy. All the work happens on the hosted server at https://usdt.chikocorp.com/mcp, which you can also connect to directly over Streamable HTTP.

Tools

Tool	Price	What it returns
check_tron_usdt_blacklist	Free (daily limit per caller)	Live read of the USDT TRC20 contract: blacklisted or not
screen_tron_address	$0.10 with x402, or 1 credit	Freeze status, OFAC SDN and OpenSanctions matches, Chainabuse reports, explainable risk score
tron_usdt_aml_report	$1.00 with x402, or 1 credit	Everything in the screen, plus Tether freeze history, 1-hop counterparty exposure and tracing, and a short summary

Each tool takes one input: { "address": "T..." }. Only send public TRON addresses. Never send seed phrases or private keys.

Failed paid calls are never charged. Each signed x402 payment pays for one call. A failed free check still counts toward the daily limit.

Paying for the paid tools

Pick one of these:

• API key (credits). Create a key with the screen:write scope at https://usdt.chikocorp.com/settings. Each paid call costs 1 credit (1 credit = 1 USDT). Set it as TRON_USDT_API_KEY here, or send Authorization: Bearer <key> when you connect to the remote server directly.
• x402 (USDC on Base). Call without an API key. The first call returns a PaymentRequired result (isError: true, x402 v2 payload in structuredContent). Sign the payment and retry with it in _meta["x402/payment"]. Clients built on @x402/mcp do this automatically.

Install

Remote (no install)

Claude Code:

claude mcp add --transport http tron-usdt-risk https://usdt.chikocorp.com/mcp
# with an API key for the paid tools:
claude mcp add --transport http tron-usdt-risk https://usdt.chikocorp.com/mcp --header "Authorization: Bearer usk_live_..."

Any client that takes a JSON config:

{
  "mcpServers": {
    "tron-usdt-risk": {
      "type": "http",
      "url": "https://usdt.chikocorp.com/mcp",
      "headers": { "Authorization": "Bearer usk_live_..." }
    }
  }
}

Leave out headers to use only the free tool, or to pay per call with x402. A wrong key gets HTTP 403 on every request, so remove the header rather than leaving a bad key in place.

The server takes one JSON-RPC message per request (no batching). Limits: 60 requests a minute and 50 free checks a day, counted per API-key user, or per IP address when there's no key. Hosted clients that share an IP address also share those limits, so add an API key to get your own.

Local stdio (this package)

{
  "mcpServers": {
    "tron-usdt-risk": {
      "command": "npx",
      "args": ["-y", "tron-usdt-mcp"],
      "env": { "TRON_USDT_API_KEY": "usk_live_..." }
    }
  }
}

Variable	Required	Default
TRON_USDT_API_KEY	No	Not set: free tool plus x402 only. A wrong key blocks every tool, including the free one (INVALID_API_KEY)
TRON_USDT_MCP_URL	No	https://usdt.chikocorp.com/mcp (https only; http only for localhost)

Docker

docker build -t tron-usdt-mcp .
docker run -i --rm -e TRON_USDT_API_KEY tron-usdt-mcp

Privacy

The proxy writes nothing to disk, and it never logs addresses, API keys or payment payloads. The hosted server does not log screened addresses either.
