About

OpenViking is an open source context database designed specifically for AI agents, built around a file-system paradigm that unifies the management of memories, resources, and skills. Instead of treating context as scattered chunks in a fragmented vector store, OpenViking organizes agent context into a virtual file system under the viking protocol, giving agents a structured way to store, navigate, retrieve, and observe the information they need. It is designed to help developers move beyond the hassle of manual context management by giving agents a minimalist interaction model for context, similar to reading and writing files. OpenViking supports hierarchical context loading, semantic retrieval, recursive retrieval, sessions, metrics, and observability, making it possible for AI agents to access the right level of information without stuffing everything into the prompt.

About

octobrain is an open-source persistent memory server for AI assistants, delivered as a Rust command-line application and Model Context Protocol (MCP) server. It stores notes, decisions, project context, and indexed documents so compatible assistants can retrieve information across conversations. Features include semantic and hybrid BM25/vector search, linked memories, project-scoped stores, goal consolidation, and a knowledge base that indexes URLs, PDFs, and common document formats. Teams can distribute shared knowledge through Git-backed knowledge boxes. octobrain runs with local embedding models or optional cloud embedding providers, and exposes tools for saving, searching, and deleting memories. It is designed for developers and teams extending MCP-compatible AI assistants with persistent, searchable context; installation and operation are managed on the user's own machine or environment.
