MCP servers configuration manager for Claude Desktop
An MCP App you install into Claude Desktop that gives you an inline UI for editing claudedesktopconfig.json — add, remove, and update MCP server entries without opening the file in a text editor.
- One model-visible tool: open-mcp-config-manager — opens the panel. - The panel then: - reads the current config (path resolved per-OS) - shows each server as an editable card (name, command, args, env) - lets you add servers from templates (filesystem, github, sqlite, postgres, memory) or blank - saves back with an atomic write and a timestamped backup of the previous file - Save & restart Claude — after a successful save it automatically quits and relaunches Claude Desktop so the new config takes effect - Non-mcpServers keys in the JSON are preserved verbatim.
- The model cannot see your existing server list, args, or env vars — the read/write/restart tools are marked visibility: ["app"], so only the UI (which you, the user, drive) can call them. - Every write is triggered by clicking Save & restart Claude in the panel. The model has no way to add a rogue MCP server behind your back, and no way to restart the app on its own. - Every save writes a claudedesktopconfig.json.bak. next to the file first, so you can always roll back.
Works on macOS, Windows (installer and Microsoft Store builds), and Linux (community Claude Desktop builds; XDGCONFIGHOME is honored when set). The config path, the running-status check, and the save-and-restart flow each have per-OS implementations:
