Connect BlockchainAnalysis and your agent gets 11 tools, among them check_stablecoin_freeze, check_token_approvals, check_token_security. It answers at https://blockchainanalysis.io/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Compliance MCP for AI agents: sanctions & KYT screening on 50+ chains, stablecoin-freeze, oracle.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_stablecoin_freeze | 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, Inputs: address, chain |
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. The wallet' Inputs: wallet |
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 lab Inputs: token, chain |
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 Et Inputs: address, chain, kind, since, limit |
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. Paid per call via x402 (USDC on Base Inputs: address, chain |
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. Paid per call via x40 Inputs: from, to, chain |
list_supported_chains | 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 | 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. Answers 'is it safe to interact with this address?' Paid per call via x Inputs: address, chain |
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 con Inputs: address, chain |
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. Del Inputs: address, chain, fail_mode |
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 Inputs: address, chain, fail_mode |

It answered our last check on 18 October 2026 in 267 ms. Over 10 checks since 5 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by blockchainanalysis.io and served from blockchainanalysis.io, the vendor's own domain: https://blockchainanalysis.io/api/mcp.
11, as returned by the server's own tools/list on 31 August 2026: check_stablecoin_freeze, check_token_approvals, check_token_security, get_freeze_events, kyt_risk, kyt_tx, list_supported_chains, oracle_verdict, and 3 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://blockchainanalysis.io/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.blockchainanalysis. Endpoint host: blockchainanalysis.io. ARD identifier: urn:air:io.blockchainanalysis:mcp:mcp.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
