v0.4.0

🚀 FastAPI-MCP now supports Streamable HTTP transport.

HTTP transport is now the recommended approach, following the specification that positions HTTP as the standard while maintaining SSE for backwards compatibility.

⚠️ Breaking Changes

• mount() method is deprecated and will be removed in a future version. Use mount_http() for HTTP transport (recommended) or mount_sse() for SSE transport.

Added

• 🎉 Streamable HTTP Transport Support - New mount_http() method implementing the MCP Streamable HTTP specification
• 🎉 Stateful Session Management - For both HTTP and SSE transports
