langflow
A powerful Python-based visual framework for building and deploying AI-powered agents and workflows with Model Context Protocol (MCP) integration, drag-and-drop interface, and enterprise-grade deployment options
npx skills add majiayu000/claude-skill-registry --skill langflow --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
What it does
Langflow provides a Python-based visual framework to build and deploy AI-powered agents and workflows. It offers a drag-and-drop canvas, a component library, and MCP integration to connect tools and external MCP servers. It supports multi-agent coordination, tool ecosystems, and various deployment options (local, Docker, Kubernetes, cloud, and API export).
How it works
- The platform exposes a visual editor (Drag-and-Drop Canvas) to connect components (Inputs/Outputs, Parameters, Python Code) to form a Flow (Workflow).
- Agents are LLM-powered components that can autonomously select and execute tools (Calculator, Web Search, URL Fetcher, etc.).
- MCP Client/Server enable Model Context Protocol tool access and sharing, with connection modes including JSON Config, STDIO (local), and HTTP/SSE (remote).
- Flows can be deployed locally or in containers and exposed via RESTful API endpoints. Observability is supported via LangSmith and LangFuse, with authentication and security features (API keys, CORS, HTTPS).
- Custom components can be developed in Python, and components can be versioned and exported as JSON for portability.
When to use it
- When you need to rapidly prototype AI workflows visually without deep coding, and you require MCP tool integration and multi-agent orchestration.
- When deploying AI workflows in local, Docker, Kubernetes, or cloud environments and needing observability and security features.
What it can touch
- Tools and components within Langflow (Agent, MCP Tools, Data Sources, etc.).
- Deployment environments: Local development, Docker containers, Kubernetes, Cloud platforms.
- API endpoints for external integrations and flow export in JSON.
Caveats
- Requires Python 3.10-3.13 for desktops/macOS/Linux or 3.10-3.12 for Windows.
- Desktop version note: some features like Shareable Playground and Voice Mode may be unavailable.
- Licensing is MIT.

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill langflow --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
