  "summary": "Open-source visual builder for AI agents and workflows in Python; every flow can be served as an API or exposed as an MCP server.",
  "description": "Visual canvas plus Python source access for every component, an interactive playground, multi-agent orchestration, and deployment as a REST API, exported JSON, or an **MCP server** that turns flows into tools for MCP clients. Observability integrations include LangSmith and Langfuse. Install with `uv pip install langflow -U` and run `uv run langflow run` (serves on `127.0.0.1:7860`); official release packages disable auto-login, so set `LANGFLOW_SUPERUSER_PASSWORD` first. Langflow Desktop bundles all dependencies for Windows and macOS. Latest release v1.13.0 (2026-10-22).",
