Open MCP Apps runs on your own machine — the client starts it, so there is no endpoint to ping. 132 installs a week from npm. Last commit 16 Oct 2026.
Persistent, interactive MCP Apps — the AI builds an app once, you both reuse it

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Optional settings from the registry entry, left out of the block above:
OMA_DB (Path to the SQLite store. Defaults to a fixed per-user data directory; set this to isolate a store), OMA_VIEWER (Browser viewer on loopback. On by default; set to 0 to turn it off), OMA_DYNAMIC_TOOLS (Set to 1 to also expose one open_<name> tool per saved app. Off by default, because it costs prompt cache).
