rohkun 2.2.2.2

Client-side code analysis tool for API connections

Rohkun CLI v2

Client-side code analysis tool that finds API connections in your codebase.

Features

• 🚀 Fast - All analysis happens locally on your machine
• 🔒 Private - Your code never leaves your computer
• 🎯 Accurate - Finds endpoints and API calls across multiple languages
• 📊 Detailed Reports - Saved locally in .rohkun/reports/
• 💥 Blast Radius - See impact of code changes
• 📈 Confidence Scoring - Know how reliable each connection is
• 🔄 Diff Over Time - Compare reports to track changes
• ⚡ High Impact Detection - Find critical nodes in your codebase

Installation

pip install rohkun

Quick Start

1. Get your API key from rohkun.com/dashboard

2. Configure the CLI:

rohkun config --api-key YOUR_API_KEY

3. Run analysis on your project:

rohkun run

Or run on a specific directory:

rohkun run /path/to/project

Note: rohkun scan is still available as an alias for backward compatibility.

How It Works

1. Authorization Check - CLI checks with server if you have credits
2. Local Analysis - All code analysis happens on your machine
3. Snapshot Creation - Each scan automatically creates a snapshot (like Git commits)
4. Automatic Comparison - Starting from your second scan, automatically compares with previous snapshot
5. Report Generation - Results saved to .rohkun/reports/
6. Usage Tracking - CLI reports completion to server for billing

Your code is never uploaded to our servers.

Snapshot Workflow

Think of it like Git commits for your architecture:

• First scan: Creates Snapshot #1 (baseline)
• Second scan: Creates Snapshot #2, automatically compares with #1
• Third scan: Creates Snapshot #3, automatically compares with #2
• And so on...

Each scan shows you exactly what changed—new endpoints, removed API calls, broken connections, and more.

Commands Reference

Quick Reference Table

Command	Description
rohkun run [path]	Scan codebase and generate report
rohkun run [path] --visualize	Scan + open 3D visualization
rohkun config --api-key KEY	Set API key
rohkun mcp-setup	Configure MCP for AI assistants
rohkun --version	Show version
rohkun --help	Show all commands

rohkun run - Analyze Codebase

rohkun run [path] [options]

Scans your codebase for API endpoints, connections, and dependencies.

Arguments:

• path - Directory to scan (default: current directory)

Options:

• --visualize - Generate and open interactive 3D knowledge graph
• -v, --verbose - Show detailed output (blast radius, confidence scores)

Examples:

# Scan current directory
rohkun run

# Scan specific folder
rohkun run ./my-project

# Scan with visualization
rohkun run ./my-project --visualize

# Verbose output
rohkun run -v

Note: rohkun scan is an alias for backward compatibility.

---

rohkun config - Configure CLI

rohkun config --api-key YOUR_KEY

Saves API key to .rohkun/config.json in your project.

Environment Variables (alternative):

export ROHKUN_API_KEY=your_key_here
export ROHKUN_API_URL=https://custom-api.com  # For self-hosted

---

rohkun mcp-setup - Setup AI Integration

rohkun mcp-setup [options]

One command to configure MCP (Model Context Protocol) for AI assistants.

What it does:

• ✅ Checks Rohkun installation
• ✅ Uses existing API key (or prompts for one)
• ✅ Auto-detects IDE (Cursor/Claude Desktop)
• ✅ Creates/updates MCP config file
• ✅ Works alongside other MCP servers

Options:

• --ide cursor|claude - Force specific IDE
• --api-key KEY - Provide API key directly

After setup: Restart your IDE, then ask your AI:

• "What endpoints does this project have?"
• "Analyze the codebase structure"
• "Show me what changed since last scan"

---

rohkun --version

rohkun --version

Shows current CLI version (e.g., Rohkun CLI v2.2.2).

---

MCP Server (For AI Integration)

The MCP server (rohkun-mcp) is separate from the main CLI. It's designed to be called by AI assistants, not run manually.

How MCP Works

1. Setup: Run rohkun mcp-setup once
2. Restart: Restart your IDE (Cursor/Claude Desktop)
3. Use: Ask your AI about code structure - it automatically calls Rohkun

MCP Tools Available

Tool	Description
analyze_codebase	Full codebase analysis
check_impact	Check impact of changes to a file/endpoint
show_changes	Compare current state to previous snapshot
visualize_architecture	Generate knowledge graph
list_snapshots	List available snapshots

MCP Troubleshooting

"Parse error: Expecting value" - The MCP server is trying to read JSON from stdin. This happens if:

• You accidentally ran rohkun-mcp directly (don't do this)
• A terminal has a stuck MCP process

Fix: Close terminal, open fresh one, use rohkun run not rohkun-mcp.

# Check for stuck processes
tasklist | findstr python

# Kill if needed
taskkill /F /IM python.exe

---

rohkun --help

rohkun --help

Shows all available commands and options.

Supported Languages

• Python (Flask, FastAPI, Django)
• JavaScript/TypeScript (Express, Next.js, React)
• Go (net/http, Gin, Echo)
• Java (Spring Boot)
• And more...
