Show HN: Overture – Interactive plan viewer for AI coding agents (open source)

As a daily Claude Code and Cursor user, something that kept frustrating me is that plans are just a flat list of steps in the terminal and chat screen. I can't monitor what's happening at each step while it runs — I just wait for the whole thing to finish and hope it worked. If I want to restructure the plan, I'm copy-pasting text around in a chat box. I can't attach specific instructions or files to step 4 without it leaking into step 7. I can't tell one step to use the Figma MCP and another to use Supabase.

So I built Overture. It's an open-source MCP server that takes the agent's plan and turns it into an interactive node graph in your browser before any code gets written.

I can now click into any step and attach exactly what it needs — files, docs, API keys, an MCP server, special instructions — scoped to just that step. I can drag to reorder, delete steps, add new ones. I can see which steps depend on which. When the plan has a branch point (like Stripe Checkout vs Stripe Elements), I can pick one or run both in parallel and choose the winner. During execution, each node updates individually — green when done, red with logs when failed, and I can inspect the output of any step without waiting for the full run to finish.

Works with Claude Code, Cursor, Cline, Codex — anything that supports MCP. Plans are structured XML under the hood, and agents can declare input fields per step ("this step needs a Stripe API key") so I fill everything in upfront instead of getting interrupted mid-execution.

npx overture to try it. Everything runs locally.

Still early — contributions very welcome. Graph rendering, layout algorithms, and getting agents to consistently generate structured plans are all areas that need work.
