What is kimi-mneme?

kimi-mneme is a Kimi Code CLI plugin that adds persistent memory to your coding sessions. It automatically captures context, compresses it with AI, and injects relevant past observations into future sessions. Never lose track of what you were doing — even after days or weeks.

💡 Looking for Kimi plugins? This is an official-style plugin for the Kimi CLI ecosystem. Install with uv tool install kimi-mneme and run mneme bootstrap to get started.

Why kimi-mneme?

• Never lose context — Your coding history survives across sessions, restarts, and even weeks of inactivity
• AI-powered memory — Automatically structures raw tool outputs into searchable observations
• Zero configuration — Works out of the box with Kimi Code CLI
• Privacy-first — Local SQLite storage; AI structuring/compression are optional and can be disabled
• Cross-platform — Windows, macOS, Linux support

Offline Behavior & Privacy

kimi-mneme is designed to work fully offline with graceful degradation when AI services are unavailable:

Feature	With API (online)	Without API (offline)
Observation storage	✅ Full	✅ Full (always local)
Full-text search (FTS5)	✅ Full	✅ Full (local SQLite)
Semantic search (sqlite-vec)	✅ Full	✅ Full (local embeddings)
Session timeline	✅ Full	✅ Full
Context injection	✅ Full	✅ Full (heuristic-based)
AI structuring	✅ Rich metadata (type, facts, concepts)	⚠️ Heuristic fallback (rule-based)
AI compression	✅ Semantic summaries	⚠️ Raw observations stored
Pattern detection	✅ AI + heuristic	⚠️ Heuristic only
Web viewer	✅ Full	✅ Full
MCP tools	✅ Full	✅ Full

Privacy note: When AI structuring is enabled, tool outputs are sent to the configured LLM provider after applying 3-layer sanitization (system content stripped, secrets redacted, privacy tags removed). No raw credentials, tokens, or <private> blocks ever leave your machine. Use Ollama or other local LLM for 100% offline operation with zero network calls.

Who is this for?

• Developers using Kimi Code CLI who want persistent project memory
• Teams working on complex codebases across multiple sessions
• Anyone looking for kimi plugins to extend their CLI workflow
• Users of Moonshot AI ecosystem tools

Key Features

Feature	Description
🧠 Persistent Memory	Context survives across sessions, restarts, and reboots
🤖 AI Structuring	Raw tool outputs → structured observations (title, facts, narrative, concepts) via configurable LLM (Kimi, Ollama, OpenAI-compatible)
⚡ Heuristic Fallback	Works without API key — rule-based structuring when Kimi is unavailable
🔍 Smart Search	Full-text (FTS5) + semantic (sqlite-vec) hybrid search across your project history
📊 Progressive Disclosure	3-layer retrieval: index → timeline → full details (token-efficient)
🖥️ Web Viewer	Real-time memory stream at http://localhost:37777
🔌 Kimi Plugin Tools	mneme_search, mneme_timeline, mneme_get — AI can query its own memory
🖇️ MCP Server	Claude Desktop, Cursor, Goose integration — 15 memory tools
📝 PROJECT.md	Auto-generated project context from structured observations
🔒 Privacy Tags	3-layer filtering: strip system content → redact sensitive → deep sanitize (applied before any AI processing)
📊 Knowledge Collections	Curate and query project-specific knowledge corpora
🌳 Tree-sitter Analyzer	AST-based code exploration (Python, JS, TS, Rust, Go)
💰 Token Economics	See token savings and read cost per observation
⚡ Zero Config	Install and forget — works automatically
📁 Project Config	Per-project .mneme.json for custom settings
📌 Session Checkpoints	Resume context after Kimi CLI compaction
🔁 Cross-Session Patterns	Auto-detect recurring errors, fixes, decisions
✂️ Truncation Tracking	Record when tool outputs exceed 100K chars

Quick Start

Prerequisites

• sqlite3 CLI: Required for database inspection and internal operations. Install via your system package manager (apt install sqlite3, brew install sqlite3, winget install SQLite.SQLite, etc.)

Install via uv tool (recommended — global install)

Installs mneme globally (available in any directory, like git or docker):

# Install globally as a permanent tool
uv tool install kimi-mneme

# Or install latest from GitHub
uv tool install git+https://github.com/barrelc/kimi-mneme.git

# Run bootstrap (sets up hooks, plugin, DB, server)
mneme bootstrap

# Start using Kimi CLI
kimi

Why uv tool instead of uvx?

• Global commands — mneme available everywhere, not just in project folder
• No cache issues — installed permanently, not temporary
• Faster startup — no re-installation on each run
• Easy updates — uv tool upgrade kimi-mneme

Update

Via uv (recommended)

# Update to latest version
uv tool upgrade kimi-mneme

# Re-run bootstrap to update hooks and config
mneme bootstrap

Via pip

# Update to latest version
pip install --upgrade kimi-mneme

# Re-run bootstrap to update hooks and config
mneme bootstrap

Alternative: Install via uvx (temporary, no install)

Runs without installing — useful for testing or CI:

# One-shot run (slower, re-installs each time)
uvx --refresh --from git+https://github.com/barrelc/kimi-mneme.git mneme bootstrap

⚠️ uvx caches installations. Use --refresh to force update, or switch to uv tool install for a better experience.

Local / Development Install

For contributing or hacking on the code:

# Clone and install in editable mode
git clone https://github.com/barrelc/kimi-mneme.git
cd kimi-mneme
uv pip install -e ".[dev]"

# Or with pip
pip install -e ".[dev]"

Install via pip (global)

# Install globally
pip install kimi-mneme

# Or install in user space (no sudo needed)
pip install --user kimi-mneme

mneme bootstrap

Note: pip install --user installs to ~/.local/bin (Linux/macOS) or %APPDATA%\Python\Scripts (Windows). Make sure this directory is in your PATH.

What bootstrap does

Step	What happens
Database	Creates SQLite DB at ~/.kimi/mneme/mneme.db
Hooks	Registers 4 lifecycle hooks in ~/.kimi/config.toml (auto-injects context on session start)
Plugin	Installs mneme_search, mneme_timeline, mneme_get tools into Kimi CLI
MCP Server	Registers kimi-mneme MCP server in ~/.kimi/mcp.json (15+ tools for Claude/Cursor/Goose)
Skills	Copies mem-search skill to ~/.kimi/skills/ (teaches AI the search→timeline→get workflow)
Server	Starts web dashboard at http://localhost:37777

One command = fully configured. No manual setup needed.

Recommended: Install sqlite3 CLI for database inspection and internal operations:

# Linux (Debian/Ubuntu)
apt install sqlite3

# macOS
brew install sqlite3

# Windows
winget install SQLite.SQLite

Use Kimi CLI normally

kimi

That's it. Every session is automatically captured and indexed. When you start a new session in a project, previous context is automatically injected.

Out-of-Box Experience

After mneme bootstrap, everything works automatically:

1. Auto-injected context on every kimi start — shows "What we did before" with real prompts, files, and tools
2. Plugin tools — Kimi AI can call mneme_search, mneme_timeline, mneme_get to query memory
3. MCP tools — 15+ tools including memory_search, memory_semantic_search, smart_search, smart_outline
4. Skills — Kimi learns the 3-layer workflow: search → timeline → get (10x token savings)
5. Web UI — Browse full timeline at http://localhost:37777

💡 Ask Kimi: "What did we do yesterday?" or "Search my memory for the auth bug" — it will use the memory tools automatically.

CLI Commands

mneme bootstrap          # One-shot setup (hooks, plugin, DB, server)
mneme update             # Update hooks and config to latest version
mneme server             # Start web server
mneme init               # Initialize database only
mneme stats              # Show database statistics
mneme cleanup --days 30  # Remove old observations

---

Per-Project Configuration

Create .mneme.json in your project root:

{
  "injection": {
    "max_tokens": 1000,
    "recency_boost_days": 14,
    "include_patterns": true
  },
  "privacy": {
    "exclude_patterns": ["*.local.env", "secrets/"]
  }
}

This merges with global config (project values override global).
