berkelium 0.0.2

Berkelium CLI — TUI for code graph management.

Berkelium CLI

Berkelium CLI is a Code Graph Management tool and Model Context Protocol (MCP) server. It uses tree-sitter to parse your codebase into a structured graph stored in SQLite, enabling high-fidelity impact analysis and surgical context retrieval for AI assistants.

🚀 Quick Start

Installation

# Install
pip install berkelium

# Run the TUI
berkelium-cli

Development Setup

git clone https://github.com/BerkeliumLabs/berkelium-cli
cd berkelium-cli
uv sync

🖥️ TUI Features

The Berkelium TUI (berkelium-cli) provides a terminal interface for:

• Build/Update Graph: Index supported languages (Python, JS/TS, Go, Java, Rust, C/C++).
• Incremental Sync: Uses git-diff to update the graph in milliseconds.
• Exploration: Visualize symbols and relationships directly in your terminal.

🤖 MCP Server (for AI Assistants)

Connect Berkelium to Claude, Cursor, or any MCP-compatible client to give your AI "graph-vision" over your code.

Configuration (Claude Desktop)

Add this to your claude_config.json:

{
  "mcpServers": {
    "berkelium": {
      "command": "berkelium-mcp",
    }
  }
}

Available Tools

• build_or_update_graph: Performs a full extraction or an incremental git-diff sync.
• get_impact_radius: Analyzes functional blast radius (upstream callers and downstream dependencies).
• get_structural_context: Returns Markdown-formatted context optimized for LLM injection.
• get_file_symbols: Lists all symbols (functions, classes, etc.) defined in a specific file.
• search_symbols: Locates symbols by name fragment across the entire codebase.
• query_graph: Executes read-only Cypher queries directly against the code graph.

Available Prompts

• review_my_pr: A guided workflow that syncs the graph, identifies changes via git, and suggests targeted tests based on impact analysis.

🏗️ Architecture

• Extractor (extractor.py): Language-agnostic extraction using tree-sitter.
• Store (store.py): Persistence layer using GraphQLite on SQLite.
• Sync (sync.py): Git-based incremental synchronization logic.
• Retriever (retriever.py): Graph traversal algorithms for impact and context.
