sayou

A persistent knowledge workspace that gives Claude 11 MCP tools for versioned file storage, search, and retrieval. It treats context like a file system instead of a database: every write creates a new version with YAML frontmatter for metadata, reads respect token budgets and return summaries when needed, and searches work across both content and frontmatter fields. You get workspace_write, workspace_read, workspace_search, and workspace_history for version diffs, plus glob patterns, grep, and a key-value store with TTL support. Installs via pip with auto-configuration for Claude Code, Cursor, or Windsurf. Optional cloud sync through Sayou Drive. Reach for this when you need Claude to remember research, decisions, or structured notes across sessions without everything living in chat history.
