Your AI builds the tool. You keep it.
Ask in plain words and get an interactive tool — built inline, right in your chat, in any AI that supports MCP. It stays yours, and it's reused without rebuilding.
Free · open-source · works in any MCP-capable AI
Your tools live inline — right inside the AI app you already use.
Built on the open MCP Apps standard — it works anywhere that speaks it. Tested with Claude & Codex (apps + CLIs); other MCP-capable apps should work too, and we're verifying more.
Ask for it. It appears.
Say what you want the way you'd say it to a person. Your AI builds a real, interactive tool — right there in the conversation, ready to use.
It remembers — and keeps itself current.
Your tools and their data stay put across every chat. Your AI updates them when it makes sense, and shows you the latest whenever you ask — the tool is alive, not a snapshot.
Built once. Never rebuilt.
Reopen a tool and it's instant — no tokens spent regenerating it. Turn on the library and your AI reuses ready-made tools the same way: no build, no wait, no tokens burned.
Install it, then just start.
Run one command to add it to your AI app. Then open the app and it walks you through your first tool. No account, nothing to pay.
curl -fsSL https://openmcp.app/install.sh | shRun the command
In your terminal — it installs the engine and registers it with your AI app.
Open your app
Restart your AI app (Claude, Codex, …) so it picks up your new tool-maker.
Say "onboard me"
It walks you through your first few tools, tailored to how you work.
