Counterparty Check
Check a payee before your agent pays: sanctions, lookalike domains, payment details, invoice fraud.
What it does
Counterparty Check is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
From the publisher's description, Electra Index matched it to 2 capabilities: invoicing and payments. That makes it a candidate for tasks such as detect fraudulent transactions or send and chase invoices.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.
