`mcp-publisher <command> --help` does not display help

[jonathanhefner]

mcp-publisher --help indicates that each subcommand has its own help:

$ mcp-publisher --help
MCP Registry Publisher Tool

Usage:
  mcp-publisher <command> [arguments]

Commands:
  init          Create a server.json file template
  login         Authenticate with the registry
  logout        Clear saved authentication
  publish       Publish server.json to the registry

Use 'mcp-publisher <command> --help' for more information about a command.

However, running mcp-publisher <command> --help will actually run mcp-publisher <command> instead of display its help:

$ mcp-publisher init --help
Error: server.json already exists

$ mcp-publisher login --help
Error: unknown authentication method: --help
For a list of available methods, run: mcp-publisher login

$ mcp-publisher publish --help
Publishing to https://registry.modelcontextprotocol.io...
Error: publish failed: server returned status 401: {"title":"Unauthorized","status":401,"detail":"Invalid or expired Registry JWT token","errors":[{"message":"failed to parse token: token has invalid claims: token is expired"}]}
