Desktop automation MCP server — computer use for any AI agent. See the screen, control windows/mouse/keyboard, and drive Chrome over the Model Context Protocol (stdio). Desktop & browser automation need no API key; OCR runs locally; vision plugs into your own vision LLM (OpenAI-compatible or Anthropic native, BYOK).
nuphus-mcp is a lightweight, cross-platform desktop automation MCP server
that exposes desktop + browser automation as standard MCP tools. It speaks
JSON-RPC 2.0 over stdio — no daemon, no network service, one binary. Claude
Desktop, Cursor, VS Code, Copilot, or any MCP client can connect and
immediately control the screen, windows, keyboard/mouse, and Chrome —
computer use for any AI agent — desktop & browser automation need no API
key; local OCR is built in; vision works with your own vision LLM
(OpenAI-compatible, BYOK).

Part of the Nuphus ecosystem: Nuphus — a local-first AI agent with real desktop execution and dual-device (phone-as-second-screen) sync. nuphus-mcp exposes the same desktop + browser automation to any MCP client.
Using DeepSeek Harness (DSH)? nuphus-mcp itself is a plain stdio MCP server — not a DSH/Cordis plugin. Install the dedicated dsh-nuphus-mcp plugin instead (see DeepSeek Harness (DSH)).
