CounterpartyCheck

Overview

CounterpartyCheck is an MCP server that performs pre-payment checks on EVM and Solana addresses, returning a status of ok, caution, or block along with detailed reasons for each determination. Built by Crypto Money Maker, it integrates seamlessly with any MCP-compatible AI assistant, enabling models to call its tools directly within conversations and agent workflows.

You can deploy CounterpartyCheck in two ways: connect to the hosted endpoint at https://api.youraitools.co/counterpartycheck/mcp without any local setup, or install it locally on your machine using npx -y @agentgate-builder/counterpartycheck. The current release is v0.1.1 and requires no authentication to use.

CounterpartyCheck is categorized under Finance on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership, display the Verified badge, and ensure information stays up to date.
