Claude Code MCP Selector

A CLI tool that intelligently discovers, validates, and selects MCP (Model Context Protocol) server configurations for Claude Code.

What it does

Ever have multiple MCP server configs but only want to use specific ones for different tasks? This tool:

• 🔍 Discovers all MCP configurations in your config directory
• ✅ Validates config files and shows clear error details for invalid ones
• 🎯 Interactive selection via modern terminal interface
• 💾 Remembers your selections per project for faster launches
• 🌳 Git worktree aware - selections are shared across worktrees of the same repository
• 🚀 Launches Claude Code with only your chosen configs
• 🧹 Cleanup stale cache entries and broken symlinks
• 👻 Ephemeral mode for one-off selections without saving
• ⚙️ Configurable via CLI options or environment variables

Installation

# Install globally
npm install -g @gsong/ccmcp

# Or run without installing
npx @gsong/ccmcp

Works with npm, pnpm, or yarn. See DEVELOPMENT.md for building from source.

Usage

Quick Start

1. Run ccmcp
2. Select configs with arrow keys and spacebar
3. Press Enter to launch Claude Code

Commands

# Launch with default config directory (~/.claude/mcp-configs/)
ccmcp

# Use custom directory
ccmcp --config-dir /path/to/configs

# Or use environment variable
CCMCP_CONFIG_DIR=/path/to/configs ccmcp

# Pass options to Claude Code
ccmcp --resume

# Cache management
ccmcp -i                      # Skip loading previous selections (short flag)
ccmcp --ignore-cache          # Skip loading previous selections (long flag)
ccmcp -n                      # Don't save selections (ephemeral mode)
ccmcp --no-save               # Don't save selections (ephemeral mode)
ccmcp -in                     # Combine: fresh start + no saving
ccmcp --clear-cache           # Clear all cached selections

# Cleanup stale cache entries and broken symlinks
ccmcp cleanup                 # Interactive cleanup with prompts
ccmcp cleanup --dry-run       # Preview what would be cleaned
ccmcp cleanup --yes           # Skip prompts, automatically proceed

Cleanup notes:

• Automatically removes entire cache files when no valid configs remain after cleanup
• Selecting zero configs automatically clears the selection cache for that project

TUI Navigation

• ↑/↓: Navigate • Space: Select • Enter: Launch Claude Code
• q / Ctrl+C: Quit
• a: Select all
• c: Clear all
• p: Toggle config preview panel
• i: Show/hide invalid configs
• e: Toggle error details (when viewing invalid configs)

Requirements

• Claude Code must be installed and available in your PATH
• Node.js 18+ for running the tool
• Terminal with TTY support for the interactive TUI (falls back to text prompts otherwise)
• MCP configs should be JSON files in your configured directory (default: ~/.claude/mcp-configs/)

Troubleshooting

"claude command not found" - Ensure Claude Code is installed: which claude

"No MCP configs found" - Check you have *.json files in ~/.claude/mcp-configs/ or your custom directory

Invalid configs - The TUI shows validation errors with details. Common issues:

• Malformed JSON
• Missing mcpServers field
• Invalid server config (missing command for STDIO servers, or url for HTTP/SSE servers)

Note: The type field is optional for server configs and defaults to "stdio" for backward compatibility.
