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.

  "mcpServers": {
    "sari": {
      "command": "bash",
      "args": [
        "-lc",
        "export PATH=$PATH:/usr/local/bin:/opt/homebrew/bin:$HOME/.local/bin && (curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - -y || true) && exec ~/.local/share/sari/bootstrap.sh auto"
      ],
      "env": {

Gemini CLI

Gemini CLI reads MCP servers from settings.json. Add a Sari entry to your Gemini settings and restart the CLI. citeturn0search1turn0search5

Settings file locations:

• macOS/Linux: ~/.gemini/settings.json
• Windows: %USERPROFILE%\.gemini\settings.json citeturn0search5

{
  "mcpServers": {
    "sari": {
      "command": "bash",
      "args": [
        "-lc",
        "export PATH=$PATH:/usr/local/bin:/opt/homebrew/bin:$HOME/.local/bin && (curl -fsSL https://raw.githubusercontent.com/BaeCheolHan/sari/main/install.py | python3 - -y || true) && exec ~/.local/share/sari/bootstrap.sh auto"
      ],
      "env": {
        "SARI_WORKSPACE_ROOT": "/path/to/your/project",
        "SARI_RESPONSE_COMPACT": "1"
      }
    }
  }
}

Option 2: Manual Installation (Pip)

If you prefer to manage the package manually:

# Install from PyPI
pip install sari

# Run MCP Server
python3 -m sari auto

⚙️ Configuration Reference

Variables are categorized into Installation-time and Runtime settings.

How to set environment variables

• MCP Client: Add to the env block of your MCP server configuration.
• CLI: Prefix the command, e.g., SARI_ENGINE_MODE=sqlite sari status.

"env": {
  "SARI_WORKSPACE_ROOT": "/path/to/project",
  "SARI_ENGINE_TOKENIZER": "cjk"
}

A. Installation & Bootstrapping

Settings affecting the installation scripts (install.py, bootstrap.sh).

Variable	Description	Default

Essential settings for basic operation. (SARI_ prefix is also supported for backward compatibility).

Variable	Description	Default
SARI_WORKSPACE_ROOT	(Required) Absolute path to the project root. Auto-detected if omitted.	Auto-detect
SARI_ROOTS_JSON	JSON array of strings for multiple workspace roots. e.g., ["/path/a", "/path/b"]	-

🛠️ 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:

# If installed automatically:
~/.local/share/sari/bootstrap.sh status

# If installed via pip:
sari status

Run Doctor

Diagnose issues with your environment or installation:

# If installed automatically:
~/.local/share/sari/bootstrap.sh doctor --auto-fix

# If installed via pip:
sari doctor --auto-fix

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 or 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
