Does it work on Windows or Linux?
No. The script relies on macOS-specific paths (`~/Library/Application Support/Claude/`) and commands (`killall`, `open`), so it will not work on Windows or Linux.

Overview
What is Claude MCP Config Switcher?
A command-line tool for macOS that quickly switches between different mcpServers configurations for the Claude desktop application. It lets you define multiple named profiles (e.g., “default”, “staging”, “dev”) and swap the active MCP server block in Claude’s config file without manual editing, then automatically restarts Claude to apply the changes.
How to use Claude MCP Config Switcher?
Install via the quick install command (curl -fsSL … | sh -s -- --install) or manually by running the setup.sh --install script. After installation, create .json profile files in ~/.config/claude/ containing an mcpServers key. Use the command claude-mcp-switch <profile> (or claude-mcp-switch to default to “default”) to switch, claude-mcp-switch -l to list available profiles, and claude-mcp-switch last to revert to the previous configuration.

Frequently asked questions
What dependencies are required?
The `jq` utility must be installed. It can be installed via `brew install jq`.
Where are configuration profiles stored?
Profiles are stored as `.json` files in the `~/.config/claude/` directory. Each file must contain an `mcpServers` key.
What does the script modify in Claude’s config file?
The script only reads and writes the `mcpServers` key. Other keys in the target Claude config file are preserved, and other keys in source profile files are ignored.
How do I revert to the previous configuration?
Use the command `claude-mcp-switch last`. The script saves a backup of the previous `mcpServers` block into `~/.config/claude/last.json`.
