Configuration management and security toolkit for Claude Code
CLI & MCP Server • Always-on secret detection • Dry-run by default

Why CCH?

• CLI-First: Simple commands Claude can run directly - no MCP complexity required
• Safe by Default: Every cleanup previews changes before execution
• Intelligent Cleanup: 99.4% reduction capability (14MB → 84KB)
• Security Focused: Automatic secret detection on every command
• Global Analysis: Analyzes entire Claude workspace, not just individual projects

Install

# As global CLI (recommended)
npm install -g @light-merlin-dark/claude-code-helper

# Or as package
npm install @light-merlin-dark/claude-code-helper

Quick Start

CLI:

# Clean your config (dry-run by default)
cch clean                  # Preview what will be removed
cch clean --execute        # Actually perform cleanup

# Remove empty projects
cch clean projects -e      # Execute after preview

# Security audit
cch --audit                # Analyze config health
cch --mask-secrets-now     # Emergency secret removal

With Claude:

Tell Claude to run commands directly:

• "Run cch clean to preview cleanup"
• "Use cch --audit to analyze my config"
• "Run cch --mask-secrets-now to secure my config"

Cache Optimization

Claude Code accumulates session transcripts, debug logs, and file history in ~/.claude/. Over time, this can grow to 1.5GB+. CCH provides intelligent cache management:

• Analyze cache usage - See exactly what's using space
• Safe cleanup - Remove orphaned projects, stale sessions, large files
• Blob removal - Extract large images/outputs from sessions (surgical, preserves conversations)
• Dry-run first - All commands preview changes before execution

Typical savings: 100-200MB from orphaned projects, 10-50MB from blob cleanup.

Core Commands

Clean:

cch clean              # Remove large pastes, images, dangerous permissions
cch clean projects     # Remove empty or accidental projects
cch clean history      # Clear all conversation history
cch clean help         # See all options

# All commands preview first, use --execute to run
cch clean -e           # Execute after preview

Cache Management:

cch cache stats            # Quick cache overview
cch cache analyze          # Detailed cache breakdown
cch cache clean --orphaned # Remove orphaned projects
cch cache clean --stale 60 # Clean projects not accessed in 60 days
cch cache clean --large    # Clean sessions >10MB

# Blob cleanup (remove images/large outputs from sessions)
cch blob analyze           # Find sessions with large blobs
cch blob clean             # Preview blob removal
cch blob clean --execute   # Remove blobs, preserve conversation

Security:

cch --audit                # Full config analysis
cch --audit --stats        # Quick summary
cch --mask-secrets-now     # Emergency secret masking

Permissions:

cch -lp                # List current permissions
cch -add "docker"      # Add permission (auto-expands to docker:*)
cch -ap                # Apply permissions to all projects
cch -dp                # Discover common permissions

Settings:

cch fix-settings       # Fix Claude settings validation errors
cch fix-settings -e    # Apply fixes across all projects

Fixes validation errors in bulk:

• Tool names: "git status" → "Git status"
• Wildcards: "Bash(command )" → "Bash(command :)"
• MCP tools: "mcp__tool__name" → "Mcp__tool__name"

MCP Server (Optional)

For advanced integrations, install as MCP server:

cch install            # Install as MCP server
cch uninstall          # Remove MCP server

Most users only need the CLI. MCP provides programmatic access to the same functionality.

Available tools include:

• doctor - Comprehensive diagnostics and health checks
• audit - Security analysis and config health
• backup/restore - Configuration backup management
• view-logs - Filter and search CCH logs
• reload-mcp - Reload MCP configurations
• discover-mcp-tools - Analyze MCP tool usage across projects
• list-mcps - Show all MCPs in workspace
• get-mcp-stats - MCP usage statistics
• Bulk operations: add-permission, remove-permission, add-tool, remove-tool

Ask Claude to use them:

"Use CCH to reload the aia MCP"
"Run CCH diagnostics on my setup"
"Show me recent error logs"
"Audit my configuration for issues"

Safety Features

• Always-On Secret Detection: Automatic scanning on every command
• Dry-Run by Default: All clean commands preview before execution
• Emergency Response: cch --mask-secrets-now for immediate action
• Blocked Commands: Prevents rm -rf /, fork bombs, disk formatting
• Automatic Backups: Created before any changes
• Smart Expansion: docker → docker:* automatically

Configuration

~/.claude.json         # Claude's main config (managed by Claude)
~/.cch/                # CCH configuration directory
  ├── permissions.json # Your base permissions
  ├── preferences.json # User preferences
  ├── state.json       # Usage tracking
  └── backups/         # Configuration backups

Default safe permissions when starting fresh:

• make:*, npm run:*, npm test:*
• git status, git diff:*, git log:*

Development

# Clone and setup
git clone https://github.com/light-merlin-dark/claude-code-helper.git
cd claude-code-helper
npm install

# Build and test
npm run build       # Build for production
npm run dev         # Run in development mode
bun test            # Run all tests
bun test:watch      # Watch mode

Comprehensive test coverage: unit tests, integration tests, E2E CLI tests, MCP validation, and performance benchmarks.
