Sari - Local Search MCP Server

Sari (사리)

🇰🇷 한국어 가이드 (Korean Guide)

Sari is a high-performance Local Code Search Agent implementing the Model Context Protocol (MCP). It empowers AI assistants (like Claude, Cursor, Codex) to efficiently navigate, understand, and search large codebases without sending code to external servers.

Key Features:

• ⚡ Fast Indexing: SQLite FTS5 + AST-based symbol extraction.
• 🔍 Smart Search: Hybrid ranking (Keyword + Symbol structure).
• 🧠 Code Intelligence: Call graphs, snippets management, and domain context archiving.
• 🔒 Local & Secure: All data remains on your machine. No external API dependency.

🚀 Installation & Setup

This section is written for first-time setup and daily use.

Prerequisites

• Python 3.9+
• One package manager: uv (recommended) or pip
• A workspace path you want Sari to index

Check Python:

python3 --version

5-Minute Quickstart (Recommended Path)

1. Install Sari.

# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - -y --update

# Windows (PowerShell)
irm https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python - -y --update

2. Go to your project root.

cd /absolute/path/to/your/project

3. Start daemon + HTTP for this workspace.

sari daemon start -d

4. Check health.

sari status
sari doctor

5. Connect your MCP client (see Client Configuration below).

Alternative Install Methods

uv:

uv tool install sari
uv tool install "sari[full]"   # optional extras
uv x sari status               # run without install

pip:

pip install sari
pip install "sari[full]"       # optional extras

Reinstall From PyPI (Release Validation)

Use this when you want to verify the packaged release (e.g., MCP connection fix) without local source interference.

# 1) Remove existing tool environment
uv tool uninstall sari

# 2) Force reinstall from PyPI (ignore local project config/sources and cache)
uv tool install --reinstall --refresh --no-cache --no-config --no-sources "sari[full]==0.3.13"

# 3) Verify installed tool version
uv tool list

Optional: check all published versions on PyPI before pinning.

python3 -m pip index versions sari

Pick Your Runtime Mode

• stdio mode: Best default for MCP clients that launch server subprocesses.
• HTTP mode: Useful when stdio transport is unstable in your environment.

Start HTTP directly:

SARI_WORKSPACE_ROOT=/absolute/path/to/project \
sari --transport http --http-api-port 47777 --http-daemon

HTTP MCP endpoint:

http://127.0.0.1:47777/mcp

Verification

After installation, verify your active features:

sari doctor
# If 'sari' command is not found, use:
# python3 -m sari doctor

---

🔌 Client Configuration

Choose one of the options below.

Option A: Auto-write config (recommended)

Use this when you want Sari to write config for you.

# Writes workspace-local config files:
#   .codex/config.toml, .gemini/config.toml
sari --cmd install --host codex
sari --cmd install --host gemini
sari --cmd install --host claude
sari --cmd install --host cursor

Preview only:

sari --cmd install --host codex --print

Option B: Manual stdio config

Use this when you want full manual control.

Codex / Gemini TOML (.codex/config.toml or .gemini/config.toml):

[mcp_servers.sari]
command = "sari"
args = ["--transport", "stdio", "--format", "pack"]
env = { SARI_WORKSPACE_ROOT = "/absolute/path/to/project" }
startup_timeout_sec = 60

Gemini legacy JSON (~/.gemini/settings.json):

{
  "mcpServers": {
    "sari": {
      "command": "sari",
      "args": ["--transport", "stdio", "--format", "pack"],
      "env": {
        "SARI_WORKSPACE_ROOT": "/absolute/path/to/project"
      }
    }
  }
}

Claude Desktop / Cursor JSON:

{
  "mcpServers": {
    "sari": {
      "command": "sari",
      "args": ["--transport", "stdio", "--format", "pack"],
      "env": {
        "SARI_WORKSPACE_ROOT": "/absolute/path/to/project",
        "SARI_RESPONSE_COMPACT": "1"
      }
    }
  }
}

Option C: HTTP endpoint mode

Use this if your client prefers MCP-over-HTTP URL.

1. Start HTTP in background:

SARI_WORKSPACE_ROOT=/absolute/path/to/project \
sari --transport http --http-api-port 47777 --http-daemon

2. Point client MCP URL to:

http://127.0.0.1:47777/mcp

Connection Checklist

After configuring the client:

1. Restart the MCP client app/CLI session.
2. Run:

sari status

3. Confirm:

• daemon is running
• HTTP is running
• no connection error in client logs

🛠️ Usage (MCP Tools)

Once connected, your AI assistant can use these tools:

Core Tools

• search: Search for code or documentation using keywords or regex.
• read_file: Read file content (optimized for large files).
• list_files: List files in the repository.
• search_symbols: Find classes, functions, or methods by name.
• read_symbol: Read only the definition of a specific symbol (saves context).

Intelligence Tools

• call_graph: Analyze function call relationships (upstream/downstream).
• save_snippet / get_snippet: Save and retrieve important code blocks with tags.
• archive_context / get_context: Store domain knowledge and design decisions.
• grep_and_read: Search and read top N files in one go (Composite tool).

🩺 Troubleshooting

Check Status

You can check the daemon status and indexing progress:

sari status

sari status will automatically use the actual HTTP port recorded in .codex/tools/sari/data/server.json (workspace-local). The daemon port is discovered via the global registry at ~/.local/share/sari/server.json, so clients can reconnect without manual port changes.

If Daemon Port Is Busy

If you see a message like "Daemon already running" but things still don't work, another process may be using the default port.

# Try a different daemon port:
SARI_DAEMON_PORT=47790 sari daemon start -d

Run Daemon + HTTP Together

sari status talks to the HTTP server, so you should run the daemon and HTTP together. The daemon auto-starts HTTP for the current workspace.

# Start both (daemon will auto-start HTTP):
sari daemon start -d

# If you need a custom workspace:
SARI_WORKSPACE_ROOT=/path/to/workspace sari daemon start -d

Zero-Downtime Upgrade (Port Split)

You can run a new daemon+HTTP on different ports, switch clients, then stop the old one.

# Start new instance on alternate ports:
sari daemon start -d --daemon-port 47790 --http-port 47778

# Check new instance:
sari status --daemon-port 47790 --http-port 47778

Run Doctor

Diagnose issues with your environment or installation:

sari doctor

Advanced doctor flags (including --auto-fix) are available via:

python3 -m sari.mcp.cli doctor --auto-fix

Update

Update Sari using the installer script:

curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - --update -y

After updating, restart the daemon to load the new version:

pkill -f "sari.mcp.daemon"
sari daemon start -d

The bootstrap script now starts a new daemon on a free port automatically to allow zero-downtime updates.

Storage Maintenance

To prevent unlimited growth of auxiliary data (snippets, error logs, etc.), Sari implements TTL (Time-To-Live) policies. Existing data is automatically cleaned up based on TTL settings, or you can manually trigger it.

Manual Prune:

# Prune all tables using default/configured TTL
python3 -m sari.mcp.cli prune

# Prune specific table with custom days
python3 -m sari.mcp.cli prune --table failed_tasks --days 3

TTL Configuration (Environment Variables):

• SARI_STORAGE_TTL_DAYS_SNIPPETS (Default: 30)
• SARI_STORAGE_TTL_DAYS_FAILED_TASKS (Default: 7)
• SARI_STORAGE_TTL_DAYS_CONTEXTS (Default: 30)

Uninstall

To remove Sari, indexed data, and default configs:

# macOS/Linux
curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - --uninstall

# Windows
irm https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python - --uninstall

To also remove workspace-local caches (if used), pass the workspace root:

curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - --uninstall --workspace-root /path/to/project

The uninstall command also scans your home directory for .codex/tools/sari caches and removes them (best effort).

If you set SARI_CONFIG to a custom path and want that file removed too, pass:

curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - --uninstall --force-config
