Counterparty Check MCP

An MCP server that allows AI agents to screen payees before making payments. It checks against US sanctions lists, detects lookalike domains, validates bank and wallet details, and identifies invoice fraud patterns. The server provides tools to check counterparty risk, screen sanctions, check API balance, and verify receipts, returning a verdict of proceed, review, or block.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http counterparty-check-mcp https://counterpartycheck.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add counterparty-check-mcp --url https://counterpartycheck.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable counterparty-check-mcp in your MCP settings.

{
  "mcpServers": {
    "counterparty-check-mcp": {
      "url": "https://counterpartycheck.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

{
  "mcpServers": {
    "counterparty-check-mcp": {
      "type": "streamableHttp",
      "url": "https://counterpartycheck.com/mcp",
      "disabled": false
