SHARC provides semantic code search capabilities through the Model Context Protocol (MCP). This guide will help you set up SHARC with your preferred AI assistant.

​
Prerequisites

Before you begin, ensure you have:
  • Node.js 18+ installed
  • A SHARC API key — sign in at sharc.sh with Google or GitHub, then create one at Dashboard → API Keys
  • An MCP-compatible AI assistant (Claude Code, Codex, Droid, OpenCode, Cursor, etc.)

​
Quick Start

The fastest way to get started is with Claude Code: 
claude mcp add sharc -e SHARC_API_KEY=sk_mcp_... -- npx -y @sharc-code/mcp@latest
That’s it! Now you can index and search your codebases: 
> Index this codebase for semantic search

● index_codebase (MCP)
  ⎿ Indexed 2,450 chunks from 342 files in 18.3s

> How does authentication work?

● search_code (MCP)
  ⎿ Found 3 results with scores 0.94-0.98

How It Works

  1. Index your codebase - SHARC analyzes your code, splits it into semantic chunks, and creates embeddings
  2. Ask questions - Use natural language to search for code functionality
  3. Get precise results - Receive ranked code snippets with relevance scores
  4. Stay updated - File watching keeps your index current as you code
