MCP Implementations and Rails World Preparations

Andrew and David catch up on everything from wild weather and the upcoming Rails World conference to Andrew’s latest deep dive into MCPs (Model Context Protocols). Andrew shares what he’s learned while building an MCP for a Rails side project, including choosing the official Ruby MCP SDK, discovering the limitations of resources versus tools, and wrestling with OAuth and Doorkeeper authorization. They also look ahead to Rails World in Austin, highlighting talks on Active Search, Ractors, Herb, Action Text, Solid Cable, custom Rails generators, and appropriately enough MCPs.
