Nuzo
Local-first, auditable memory for AI agents.
Durable context for Codex, Claude Code, and MCP-compatible hosts—without turning memory into hidden state.
Install · 60-second demo · Why Nuzo? · Security · MCP contract
Nuzo keeps scoped memories in local SQLite. Agents can recall bounded context across sessions, while you retain a CLI and public MCP contract to inspect, update, export, archive, or delete every record. Inferred memories remain drafts until you confirm them; recalled content remains untrusted data.
[!IMPORTANT] Nuzo
1.2.0is the final planned release. The repository becomes read-only after publication, and no ongoing maintenance or security response is promised. Published packages remain available for reproducible use and forking. See the end-of-maintenance notice.
Quick Start
Use Node.js 22 LTS or 24 LTS with npm 10 or newer:
npm install --global @nuzo/memory@1.2.0
nuzo setup
nuzo setup detects Codex and Claude Code, previews host changes, and asks
before writing configuration. To evaluate Nuzo without configuring a host or
touching your normal store, run the
disposable 60-second demo.
Two read-only recall hooks are expected: SessionStart and
UserPromptSubmit. They do not write memory.
Non-interactive setup and upgrade commands
nuzo setup --codex --yes
nuzo setup --claude-code --yes
nuzo setup --all --yes
nuzo update --yes
nuzo memory manage
The Memory Loop
Automatic host hooks only recall. Explicit requests can write directly; inferred capture uses a visible suggest-and-confirm flow. The same core policy applies through the CLI, MCP server, and supported host integrations.

Proof, Not Promises
| Claim | Repository contract |
|---|---|
| Local by default | SQLite and SQLite FTS are canonical; telemetry and network embeddings are off by default. |
| Auditable lifecycle | MCP tools cover history and audit alongside update, archive, delete, export, and import. |
| Explicit inferred writes | Capture suggestions report memory_writes: false; confirmation is a separate tool. |
| Read-only automatic recall | Host hooks open existing stores read-only and fail open without writing application state. |
| Tested releases | Node 22, Node 24, docs, CodeQL, package validation, and host smoke gates are required before merge. |
Inspect the memory model, MCP tool contract, trust boundary, and release checklist.
When Nuzo Fits
Choose Nuzo when individual memories need scopes, provenance, review state, relations, audit history, bounded recall, or reuse across supported hosts.
Keep shared repository instructions in AGENTS.md. Use a short MEMORY.md
when manual curation is enough. Nuzo is not a cloud sync service, team
knowledge base, autonomous profile builder, or hosted dashboard.

Packages
| Package | Intended use |
|---|---|
@nuzo/memory | Recommended install: CLI, MCP server, and host hook runtime. |
@nuzo/memory-core | Library-level integrations. |
Source workspace packages remain private. Public packages are generated and validated through the documented release process.
Project Status
The 1.2.0 release closes the planned roadmap. The repository is retained as
an auditable reference and is not accepting new feature work. Existing users
should pin an exact version and evaluate a maintained alternative or fork for
future runtime and dependency changes. Never publish real memory data,
credentials, or exports when discussing or forking Nuzo.
