Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Screens wallets, names and companies against sanctions lists, LEI and FDIC data before an agent pays or onboards a counterparty, paid per call.

What you can do: Screen wallet addresses and person or company names against OFAC SDN, UK, EU, Canada and US CSL lists, singly or in batches of up to 25
Vet a counterparty or payee before paying, and get rule-based risk labels for EVM wallets and ERC-20 tokens
Verify companies by LEI, look up many LEIs at once, and track LEI records created or lapsed since a date
Identify and vet US banks by name or FDIC certificate
Track sanctions list entries added, removed or amended since a given date
Return the exact paid x402 or MPP request for each input, or the data itself when a prepaid key is used
When to use it: Useful when an agent handles payments, trading or onboarding and needs a sanctions or risk check on a wallet, payee, counterparty, token or company before acting, or when maintaining a KYB or sanctions-monitoring register that needs change feeds.
Requirements: Remote streamable HTTP endpoint; no account, API key or environment variables are declared. Each tool returns a paid x402 or MPP request that must be settled per call, or a prepaid key bought separately. Network access to the endpoint is required.

Before you install

Calls cost money per request (about $0.005 to $0.125 per call) and require an x402 or MPP payment client or a prepaid key; the free daily trial is limited. Screening inputs such as wallet addresses and names are sent to a third-party service. Results are rule-based labels and list matches, not a compliance determination.

Installation

In SourceWeft

Open P0: sanctions, KYB and payee checks in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank%2Fsanctions-kyb-compliance/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

sanctions_screening

Sanctions screening

Use when you need to screen a wallet address or a person/company name against sanctions lists before paying or trading: OFAC SDN, UK, EU, Canada and US CSL in one call. Returns the paid x402 request for your input (GET /sanctions/check, $0.005 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. Sanctions lists only (OFAC SDN, UK, EU, Canada, US CSL). Send address or name, not both. For a broader rule-based risk label use wallet_risk (addresses) or token_risk (tokens); for a list of addresses use sanctions_screening_batch; for a payee address before paying use check_payee; for a company or person with country or LEI use check_counterparty. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.

Bad input is refused before any charge. For one address or a name use sanctions_screening. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price.
