Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
The address to screen, in that chain's native format.
Which chain the address belongs to.
Optional signed x402 payment payload (base64, what the X-PAYMENT header carries). Omit to receive the exact payment terms; sign them (e.g. @x402/fetch) and call again with this argument to settle and get the data.

}Canonical record for an EVM chain — name, native currency, explorers, liveness-scored public RPCs. view='rpcs' returns only the ranked, eth_chainId-probed RPC list; view='wallet_config' returns a ready-to-submit EIP-3085 wallet_addEthereumChain object; view='search' finds chains by name or symbol; view='l2s' lists a parent chain's L2s.

}Resolve an ENS name to an address, or an address to its forward-verified primary name — direction is detected from the input. view='profile' returns the full identity card (multichain addresses, text records, contenthash, avatar); view='avatar' dereferences the avatar to an image URL.

}Bid-ready EIP-1559 fees (slow/standard/fast maxFeePerGas + maxPriorityFeePerGas, tx-ready wei) for one chain, read live from public RPCs. Pass tx_type to get the USD cost of that specific transaction instead, including the OP-stack L1 data fee naive estimators miss. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
