- Update validate_mcps() to accept http://, https://, and crewai-amp: URLs
- Update _get_mcp_tools_from_string() to route http:// URLs to _get_external_mcp_tools()
- Add warning log when http:// scheme is detected (security awareness)
- Update mcps field description to mention http:// support for local development
- Update HTTPTransport and MCPServerHTTP docstrings with http:// examples
- Add comprehensive tests for HTTP MCP support
This enables developers to use local MCP servers running on http://localhost
or other local HTTP endpoints during development, while maintaining security
awareness by logging warnings when http:// is used.
