Tools (13)

`check_stablecoin_freeze`read-only	Check whether Tether (USDT) or Circle (USDC) have blacklisted a wallet address on-chain. Reads the issuer's blacklist function directly across 15 chains (ETH, BSC, POLYGON, ARBITRUM, OPTIMISM, BASE, AVALANCHE, PLASMA, HYPEREVM, STABLE, INK, BERACHAIN, ROBINHOOD, TRON, SOL). A frozen address can no longer send or receive that stablecoin. Also reports whether the address was PREVIOUSLY frozen and later unfrozen (a prior-freeze signal from the freeze ledger). The result reports the observed on-chain fact (frozen / not frozen at check time), never the cause of a freeze. Free.
`check_token_approvals`read-only	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. The wallet's attack surface at a glance. Read-only. Ethereum only. Free.
`check_token_security`read-only	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. Reports observed facts (e.g. 'sell simulation reverted'), not verdicts. Live on Base, BNB Chain, Ethereum, Optimism, Polygon, Arbitrum. No transaction is sent. Free.
`get_freeze_events`read-only	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. Filter by frozen address, chain, kind, or time; omit all filters for the most recent events. This is the EVENT HISTORY — to check whether an address is frozen right now, use check_stablecoin_freeze instead. Each row is a verifiable on-chain fact (issuer acted on address at block/time); it never states the cause. Free.
`kyt_risk`read-only	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. Paid per call via x402 (USDC on Base).
`kyt_tx`read-only	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. Paid per call via x402 (USDC on Base).
`label`read-only	Look up BlockchainAnalysis's entity labels for a single address: every label on record (sanctions from OFAC / EU / UN / UK HMT / Swiss SECO, issuer-freeze state, scam, phishing, exploit, mixer, exchange, and more), each with its category, threat level (SAFE to CRITICAL), and full provenance (source, source URL, confidence, and the date it was last verified). This is the raw label read behind BA Intel, the only way to buy it per call with no account and no API key. An address we hold no label for returns an explicit not-found with the reason, never an empty result, and an absent label is not a statement that the address is safe. Paid per call via x402 (USDC on Base).
`list_supported_chains`read-only	List the BlockchainAnalysis MCP tools, the chains each supports, and pricing. Call this first to discover what the server can do (and which calls are free vs paid) before invoking a tool. Free.
`oracle_verdict`read-only	Consumer-protection verdict for a wallet or contract: a normalized verdict (safe / warning / danger, or unknown) with a 0-100 score, confidence tier, and plain-language reasons. Answers 'is it safe to interact with this address?' Paid per call via x402 (USDC on Base).
`rwa`read-only	Identify a tokenized real-world asset from its token address: what it represents, who issues it, its asset class, ISIN and issuer jurisdiction, whether transfers are permissioned, and every chain the issuer publishes it on. Each answer carries its provenance: the issuer source, how the address was established (issuer-registry / issuer-page-only / third-party), a confidence, and the date the address was last round-tripped on-chain. An address we do not recognise returns an explicit not-found with the reason, never an empty result. Does NOT cover the issuer's control over a balance (pause, blocklist, seizure). Paid per call via x402 (USDC on Base).
`screen_address`read-only	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. Works across major EVM chains plus TRON, SOL, and BTC. Paid per call via x402 (USDC on Base).
`screen_agent_wallet`read-only	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. Deliberately a verdict only — the label detail, freeze history, and scores are in the paid screen_address / kyt_risk tools, and a signed, on-chain-anchored proof is in the paid screen_agent_wallet_attested tool. Free.
`screen_agent_wallet_attested`read-only	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. The free screen_agent_wallet tool returns the verdict only. Paid per call via x402 (USDC on Base).
