check_stablecoin_freeze

Check whether Tether (USDT) or Circle (USDC) have blacklisted a wallet address on-chain.

Inferred read-only

get_freeze_events

Query the canonical stablecoin freeze ledger — the HISTORY of freeze / unfreeze / destroy events by Tether (USDT), Circle (USDC/EURC), Paxos (USDP) and First Digital (FDUSD), sourced from the issuers' own on-chain blacklist events across Ethereum, Polygon, Optimism, TRON and more.

Potential side effects

check_token_security

Simulate a buy-and-sell of an ERC-20 token on its main DEXes to surface honeypots (tokens you can buy but not sell), extreme transfer taxes, name/symbol impersonation, and active mint authority — cross-referenced against BA's 1B+ entity labels.

Potential side effects

check_token_approvals

List a wallet's active ERC-20 token approvals on Ethereum and who can move its funds — risk-scored against BA's 1B+ entity labels (scam / phishing / exploit / sanctioned spenders), flagging unlimited allowances and stale grants.

Inferred read-only

screen_agent_wallet

Boolean compliance verdict for an agent wallet or counterparty: clear / flagged / unknown, plus the top risk category, screened against BA's 1B+ entity labels (sanctions, scam, phishing, exploit, mixer) and live stablecoin freeze state.

Inferred read-only

list_supported_chains

List the BlockchainAnalysis MCP tools, the chains each supports, and pricing.

Inferred read-only

screen_address

Screen a wallet against BlockchainAnalysis's 1B+ entity-label dataset: sanctions (OFAC / EU / UN / UK HMT / Swiss SECO), scam, phishing, exploit, mixer, exchange, and more — each label carries a threat level (SAFE→CRITICAL), source, and confidence.

Inferred read-only

kyt_risk

Assess a wallet's KYT (Know-Your-Transaction) risk: sanctions + entity classification + VASP/jurisdiction score + cluster context → one risk verdict (critical / high / medium / low / unknown) with flags.

Inferred read-only

kyt_tx

Transaction KYT: screens BOTH counterparties of a transfer (from → to) against sanctions + entity + VASP + cluster, returning a combined risk level, a block/review/allow recommendation, and directional FROM:/TO: flags.

Potential side effects

oracle_verdict

Consumer-protection verdict for a wallet or contract: a normalized verdict (safe / caution / high_risk) with a 0-100 score, confidence tier, and plain-language reasons.

Inferred read-only

screen_agent_wallet_attested

Screen an agent wallet and return a SIGNED, on-chain-anchored compliance attestation: the verdict (clear / flagged / unknown) plus an EIP-712 (secp256k1) signature over the result and a BA Stamp anchor, so a third party or a smart contract can verify it offline via ecrecover without trusting us live.

Inferred read-only
