Pocketlantern

PocketLantern is an open-source, blocker-aware decision layer for AI coding agents, providing source-linked, time-sensitive decision cards and blocker warnings across tech stack decisions like authentication, front-ends, databases, AI APIs, and more. It runs as an MCP (Model Context Protocol) server, enabling AI agents and developers to instantly access relevant facts and constraints for technology migrations, upgrades, and purchases with a local, fully structured knowledge base. Target users include developers using AI coding assistants (like Claude Code or Cursor) who need up-to-date, actionable insights to avoid technical pitfalls and stale training data.
