Pocketlantern

PocketLantern is an open-source MCP (Model Context Protocol) server that serves as a blocker-aware decision layer for AI coding agents. It enables agents to answer queries about migration, upgrades, vendor decisions, and licensing by surfacing up-to-date, source-linked decision cards and blocker warnings—covering critical breaking changes, deprecations, and lock-in issues across development and infrastructure stacks. Designed for integration with AI code agents like Claude Code and Cursor, it's a fast, local lookup server useful for developers and engineering teams who want AI-generated answers grounded in verifiable, timely facts.
