A research library that lets Claude save web pages and notes as clean markdown, then organize them into collections you can query later. The MCP exposes operations to save URLs, browse collections, search your archive, and distill entire collections into focused context summaries. Think of it as persistent memory for research workflows: your agent can capture a dozen articles mid-conversation, organize them by project, then synthesize the collection into dense reference material that survives across sessions. Also includes structured "skills" for tracking living project docs and feature specs that update surgically over time. Free tier gives you 100 saves and full MCP access, pro unlocks unlimited storage and team workspaces.
