Open Mcp Apps

Overview

Open Mcp Apps is a Model Context Protocol (MCP) server: Persistent, interactive MCP Apps — the AI builds an app once, you both reuse it. In practice that means any MCP-compatible AI assistant can call Open Mcp Apps's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package @2nd1st/open-mcp-apps speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.5.9, published under the MIT license, with source at 2nd1st/open-mcp-apps on GitHub, where it has earned 27 stars.

Open Mcp Apps is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
