traql
AML risk scoring for crypto addresses and transactions on Ethereum, BSC, TRON, TON, Bitcoin
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
@traql/mcpclaude mcp add traql -e 'TRAQL_API_KEY=<your traql_api_key>' -e 'TRAQL_API_URL=https://api.traql.io' -e 'TRAQL_TIMEOUT_MS=30000' -- npx -y @traql/mcp@0.1.2
{
"mcpServers": {
"traql": {
"command": "npx",
"args": [
"-y",
"@traql/mcp@0.1.2"
],
"env": {
"TRAQL_API_KEY": "<your traql_api_key>",
"TRAQL_API_URL": "https://api.traql.io",
"TRAQL_TIMEOUT_MS": "30000"
}
}
}
}
Environment variables
TRAQL_API_KEYsecret API key from https://app.traql.io. Without it the server runs on the keyless tier: a coarse verdict, 3 free checks per IP per day, then payment-gated on the hosted API.TRAQL_API_URLBase URL of the traql API. Override only when self-hosting.TRAQL_TIMEOUT_MSPer-request timeout in milliseconds.

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]

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
fromandto(optionallyamountandasset) to screen a transfer before broadcasting it. Works on every supported chain. - By hash — pass
tx_hashalone 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.

Frequently asked questions
What is traql?
AML risk scoring for crypto addresses and transactions on Ethereum, BSC, TRON, TON, Bitcoin
How do I install traql?
It runs on your machine. In Claude Code: claude mcp add traql -e 'TRAQL_API_KEY=<your traql_api_key>' -e 'TRAQL_API_URL=https://api.traql.io' -e 'TRAQL_TIMEOUT_MS=30000' -- npx -y @traql/mcp@0.1.2. For other clients, paste the JSON configuration from this page into their MCP settings.
Does traql need an API key?
Yes. It expects TRAQL_API_KEY, which you set in its configuration.
Is traql open source?
Yes. Its code is on GitHub under the MIT license.
Who maintains traql?
It is published by traql. AI.tn lists it but does not maintain or endorse it.
From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
