Mcp Server

realopengroup/mcp-server

Connects to RealOpen's crypto real estate platform to answer questions about buying property with Bitcoin, Ethereum, stablecoins, and other crypto. The public endpoint surfaces their knowledge base with tools for fee structure, supported cryptocurrencies, transaction workflows, and service areas. The authenticated endpoint adds account management: add crypto wallets, verify ownership via signature or dust transfer, check KYC status, and generate proof of funds letters as PDFs. Built for buyers who want to present crypto holdings to sellers without liquidating to fiat first, and for agents who need to understand the crypto closing process. Uses Streamable HTTP transport with OAuth 2.1 for the authenticated flow.
