@traql/mcp

traql MCP server

AML and compliance risk scoring for crypto addresses and transactions, exposed to AI agents over the Model Context Protocol.

Ask your agent "is it safe to send to this address?" and it gets back a 0–100 risk score, a band, the risk categories behind it, and — with an API key — every individual signal with its source and confidence.

ethereum address 0x8589427373d6d84e98730d7795d8f6f8731fda16
RISK 100/100 — CRITICAL
Flags: sanctions, mixer, scam

Signals (21):
  +80  [sanctions/eth_labels] direct.sanctions — sanctions label "Tornado.Cash: Donate" [entity Tornado.Cash: Donate, confidence 0.80]
  +68  [mixer/eth_labels] direct.mixer — mixer label "Tornado.Cash: Donate" [entity Tornado.Cash: Donate, confidence 0.80]
  +10  [mixer] behavior.mixer_contact — direct contact with mixer 0xdd4c48c0b24039969fc16d1cdf626eab821d3384
  +9   [sanctions/ofac_sdn] indirect.sanctions — sent to Semenov Roman (sanctions, 18% of USDC volume) [entity Semenov Roman, confidence 1.00]
  ... and 17 more

Backed by traql: OFAC SDN, UK OFSI, EU and UN sanctions lists, Tether/Circle freeze events, curated hack and mixer attributions, and counterparty exposure analysis across Ethereum, BSC, TRON, TON and Bitcoin.

Quick start

Requires Node.js 18+.

npx -y @traql/mcp

The server speaks MCP over stdio, so you normally point a client at it rather than running it by hand.

Claude Code

claude mcp add traql --env TRAQL_API_KEY=your_key -- npx -y @traql/mcp

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "traql": {
      "command": "npx",
      "args": ["-y", "@traql/mcp"],
      "env": { "TRAQL_API_KEY": "your_key" }
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in a project) using the same mcpServers block as above.

VS Code

Add to .vscode/mcp.json:

{
  "servers": {
    "traql": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@traql/mcp"],
      "env": { "TRAQL_API_KEY": "your_key" }
    }
  }
}

Getting an API key

Sign up at app.traql.io, confirm your email — free checks are included — and issue a key under API keys. The secret is shown once; it can be rotated or revoked at any time.

Without a key the server still runs, on the keyless tier: the hosted API serves 3 free checks per IP per day so you can try it immediately, then asks for per-call payment over x402. Keyless responses are also coarser — a single reason phrase instead of itemized signals — and rate limits are tighter. For anything beyond a first look, set a key.

Configuration

Variable	Required	Default	Description
TRAQL_API_KEY	recommended	—	API key from the traql dashboard. Sent as X-API-Key. Unlocks itemized signals and higher limits.
TRAQL_API_URL	no	https://api.traql.io	Base URL of the API. Point it at your own deployment if you self-host traql.
TRAQL_TIMEOUT_MS	no	30000	Per-request timeout in milliseconds.

Tools

check_address

Scores a single address.

Argument	Type	Required	Description
chain	ethereum | bsc | tron | ton | bitcoin	yes	Network the address belongs to.
address	string	yes	Address in the chain's native format.

screen_transaction

Scores both sides of a transfer, in one of two modes:

• Pre-flight — pass from and to (optionally amount and asset) to screen a transfer before broadcasting it. Works on every supported chain.
• By hash — pass tx_hash alone to look up a transaction that is already on-chain. Supported on Ethereum, BSC, TRON and TON.

Argument	Type	Required	Description
chain	chain enum	yes	Network the transaction belongs to.
from	string	pre-flight	Sender address.
to	string	pre-flight	Recipient address.
amount	string	no	Integer amount in the asset's base units (e.g. 1000000 for 1 USDT).
asset	string	no	Asset or token symbol, e.g. USDT.
tx_hash	string	by-hash	Hash of a broadcast transaction. Mutually exclusive with from/to.

Response

Both tools return human-readable text plus structuredContent:

{
  "subject": { "type": "address", "chain": "ethereum", "address": "0x…" },
  "result": {
    "score": 100,
    "band": "critical",
    "flags": ["sanctions", "mixer", "scam"],
    "partial": false,
    "computed_at": "2026-08-23T11:42:49Z",
    "reasons": [
      {
        "code": "direct.sanctions",
        "message": "sanctions label \"Tornado.Cash: Donate\" from eth_labels (severity 100 × confidence 0.80 = 80.0)",
        "contribution": 80,
        "category": "sanctions",
        "source": "eth_labels",
        "entity": "Tornado.Cash: Donate",
        "severity": 100,
        "confidence": 0.8,
        "eff": 80.0
      }
    ]
  }
}

Score bands: clean 0–9, low 10–39, elevated 40–69, high 70–89, critical 90–100.

partial: true means an upstream data source was degraded while computing the result — read the score as a lower bound, not a final verdict.

Each successful call consumes one check from the configured account. Malformed input is rejected locally where possible, so it costs nothing.

Development

npm install
npm run build
npm test

Notes

Scores are advisory signals for triage and automation. They are not a legal determination of wrongdoing, and they do not by themselves discharge any regulatory obligation.
