What FLUJO does
FLUJO is an open-source, local-first application for building AI workflows by connecting models, MCP tools and reusable subflows on a drag-and-drop graph. Flows can be stepped through node by node in its built-in chat debugger, triggered on schedules or events, and served to other applications through OpenAI-compatible and MCP endpoints.
Why teams reach for it: FLUJO is an MCP hub and inspector in one local-first app: it installs servers from the official MCP Registry, a GitHub repo or a local folder, lets you browse and call each server's tools, resources and prompts from its detail view with a one-click connection test, and re-exposes any configured server to other MCP clients such as Claude Desktop, Cursor or Cline over Streamable HTTP, so a server is set up and inspected once instead of per client.

How will you inspect behavior and fix failures?
Inspectors & debugging tools let developers see what's happening inside an MCP connection and fix problems when something breaks.
