Overview
Langflow gives you a visual canvas for wiring LLMs, retrieval steps and tools into a flow. Every flow automatically becomes an MCP tool, so Claude, Cursor or any MCP client can call a research-and-draft pipeline you built by dragging boxes. It is MIT licensed and free to self-host, but there is no published cloud pricing.

Works with AI agents
Official MCPLangflow MCP is built in: each project on your own Langflow instance exposes its flows as MCP tools over streamable HTTP, with an API key when auth is on. Langflow can also call other MCP servers through its MCP Tools component. Vendor docs →
What a content marketer uses it for: Build a brief-to-draft flow once, then call it from Claude or Cursor whenever you need a first draft.
