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.

sayou
A file-system inspired context store for AI agents.
Built to replace the databases of the web era. Open source. File-first. SQL-compatible.
Databases were designed for transactions — they reduce nuance to fit a schema. Agents think deeply, then forget everything when the session ends. sayou is where reasoning persists, context accumulates, and knowledge compounds over time.
- Files that hold what databases can't — Frontmatter for structure. Markdown for context. Versioned. Auditable.
- One read. Full context. — Every read accepts a
token_budget. Returns summaries with section pointers when content exceeds the budget. - Knowledge that compounds — Append-only version history. Every change is a new version. Full audit trail and time-travel reads.
- Any agent can connect — MCP server, Python library, or CLI. Optional REST API with
pip install sayou[api].
Quick Start
