Rails Hyperdrive mounts an MCP (Model Context Protocol) server at /_hyperdrive/mcp in development, exposing introspection tools for AI coding agents (eval Ruby, query DB, tail logs, list models/routes, locate source, fetch docs, snapshot stack). It also ships a `hyperdrive:init` generator that discovers and installs four artifact kinds — skills, guidelines, agents, and commands — shipped by companion gems under a documented contract. rails-hyperdrive is the mechanism; companion gems (rails-hyperdrive-) are the content.
