Claude-Code -Selector

Claude Code MCP Server Selector is a fast, interactive TUI tool for managing MCP servers used by Claude Code. It discovers all available MCP servers, merges configuration from multiple sources, and lets you enable or disable specific servers with a three-state toggle (RED off, GREEN on, ORANGE available but runtime-disabled). When you start the tool, it launches Claude Code with a minimized context window containing only the selected servers, helping you minimize token waste and improve performance. Use SPACE to toggle servers, and ENTER to save changes and launch Claude Code. The CLI subcommands allow scriptable control (enable/disable, list, and export utilities) and the marketplace integration can install or uninstall plugins directly from the TUI.

You can run the selector via npx (recommended) or install globally with npm. After enabling the desired set of servers, the tool forwards any additional CLI arguments straight to Claude Code, acting as a transparent wrapper. It also detects if you’re running inside a Claude session and provides guidance about when changes take effect.

Prerequisites:

• Node.js 20 or later
• npm (comes with Node.js) or npx

Installation options:

1. Install globally via npm (recommended for frequent use):

npm install -g @henkisdabro/mcp-selector

2. Run directly with npx (no installation required):

npx @henkisdabro/mcp-selector

3. Verify installation by launching the tool:

mcp --help

Notes:

• The tool is designed to work well with Claude Code and will automatically launch Claude Code with the optimized configuration after you save changes.
• You can pass through additional arguments to Claude Code after configuration; these are forwarded transparently.

Tips and common considerations:

• Enable only 2–3 MCP servers per session to maximize context efficiency and minimize token usage.
• Use the CLI subcommands (enable/disable, --all, --json, --quiet) for automation and scripting scenarios.
• If you’re running inside an active Claude session, changes take effect on the next session restart; you can use /mcp or @mention for immediate toggles.
• The tool supports marketplace plugin discovery and installation from within the TUI (NEW v2.0).
• Ensure you’re using a compatible Claude Code configuration and that MCP servers are discoverable by the selector (it merges 12+ sources with scope precedence).
