Nabu

CI crates.io docs.rs License: MIT OR Apache-2.0

The scribe for your coding agents. Durable, local, cross-tool history of everything Codex, Claude Code, OpenCode, and pi do — searchable long after the context window, the process, or the tool is gone.

Nabû is the Babylonian god of scribes and writing, written 𒀭𒀝 (dAG) in cuneiform. It does one job well: inscribe what happened so it outlasts memory.

What it is

Coding agents forget. Compaction drops detail, sessions end, and switching tools loses context. nabu captures every session as append-only JSONL, indexes it into a rebuildable SQLite full-text index, and serves it back — to you on the CLI, and to other agents over MCP — with a citation (session, tool, raw line) on every result.

• Local-first. No telemetry, no cloud, no central database. Your history stays on your machine.
• Full fidelity of what each tool exposes. Raw JSONL is the source of truth; the index is derived and rebuildable. nabu preserves upstream payloads before best-effort normalization.
• Cross-agent. One normalized event model over Codex, Claude Code, OpenCode, and pi.
• Agent-first. A read-only MCP server (search_history, get_session, …) so a new session can recover what an old one learned.

Install

cargo install nabu-cli      # installs the `nabu` binary

Optional semantic/hybrid search is behind a default-off semantic cargo feature.

Quickstart

nabu init                 # create the local store (~/.nabu)
nabu wizard               # guided install of capture hooks + MCP (or: nabu install all)
nabu search "auth bug"    # find prior work, with citations
nabu mcp serve --transport stdio   # expose history to agents

How to use

Full command reference and the MCP surface: docs/USAGE.md.

Privacy

Raw history is full fidelity and may contain secrets. It never leaves the machine by default. Use export --redact for anything shared, and purge to delete by session or date.

Status

MVP, in active development. Capture, indexing, citation-first search, and the MCP server work today.
