A thin Rails layer over the official MCP Ruby SDK. Mounts a Streamable HTTP MCP endpoint, gates access behind API-key or HTTP Basic auth, enforces fail-closed per-tool database roles, and ships seven bundled plugins (DB, Sidekiq, Solid Queue, Flipper, Rake, Cache, Custom Tools) plus a Ruby DSL for writing your own.
