What is knowledge-base-server?
knowledge-base-server gives AI agents a shared, persistent memory. It ingests your Obsidian vault, code, documents, web clippings and other sources, classifies and summarises them, and serves the results through an MCP server and REST API, so Claude Code, Codex, Gemini CLI and other MCP clients can use the same knowledge across sessions. It uses SQLite full-text search with optional embeddings and has a web dashboard. It is free and open source under the MIT licence.
Pros
- One memory shared by several AI agents
- Keeps Obsidian as the human-friendly source
- Free and open source (MIT), self-hosted
Cons
- Needs technical setup and a running server
- Young project, still growing
Who should use knowledge-base-server
Developers and Obsidian users who want their AI agents to remember context between sessions.
