Pyrite is an open-source 'second brain' that stores knowledge as markdown and YAML files in git, schema-validated and semantically searchable. It ships a CLI, REST API, web UI, plugin system and a three-tier MCP server so people, teams and AI agents can share the same knowledge base with zero hosting cost.
