VaultRubric MCP server

Free, public, read-only Model Context Protocol server for VaultRubric. VaultRubric publishes evidence-based comparisons of where to keep money: crypto exchanges, hardware and software wallets, high-yield savings accounts, and brokerages/IRAs.

The server is hosted by VaultRubric, so there is nothing to install. This repo only holds the listing metadata.
