Three new ways to expose the widget's data to other tools.

  • --mcp-server  : runs as a Model Context Protocol server over stdio.
                    Claude Code can call the get_usage tool to see its
                    own weekly limit. Add to ~/.claude.json mcpServers.
  • --print-usage : prints current usage as JSON to stdout and exits.
                    For shell scripts, statuslines, etc.
  • Local HTTP    : optional toggle in Settings → "Local HTTP endpoint".
                    NWListener on 127.0.0.1:9123, GET /usage returns
                    cached snapshot JSON. Never exposed externally.

Both server modes reuse BrowserCookieReader + ClaudeAPI, so they
honor the same multi-browser preferences as the menu bar widget.

The Settings menu now includes "MCP install instructions…" which
shows the exact ~/.claude.json snippet with the binary path and
offers to copy it to the clipboard.
