4 use cases

  • Automate a signed-in website with one saved browser profile

    Log in once in the managed Chrome profile, then let an agent run browser tasks that reuse that session.

    View prompt
    Use the nuphus-mcp server to open <site URL> in its managed browser, take a browser snapshot, and confirm the account is still signed in. Then extract <data field> from <page> and return it as a list. Verify the snapshot shows the expected account name before you extract anything.

  • Drive an existing anti-detect browser window over CDP

    Attach the server to a fingerprint browser you already run, with optional port self-healing on reopen.

    View prompt
    Use the nuphus-mcp server to attach to the external browser at http://127.0.0.1:9222 and take a browser snapshot of the current page. Return the page title and the first five interactive elements. Verify the snapshot comes from the attached window and not a managed Chrome.

  • Operate a native desktop app by its accessibility tree

    Drive native UI through Windows UIA or macOS AX using observe, candidate, execute, and verify steps.

    View prompt
    Use the nuphus-mcp semantic desktop tools to bind the window titled <window title>, pick the element labeled <element label>, and perform <action>. Return the verified state as text. Verify the state with desktop_verify_state before reporting success.

  • Combine a vision model with local OCR for exact clicks

    Use your own vision model for meaning and local OCR for pixel-precise coordinates on screen.

    View prompt
    Use the nuphus-mcp desktop_vision tool to describe where the <target label> button is on screen, then use desktop_perceive to find its exact coordinates. Click it and return a screenshot path. Verify the screenshot shows the expected change before you report success.

How to use Nuphus MCP

  1. Check you have what it needs: Rust stable toolchain to build from source with Cargo; Chrome or Edge installed for browser tools; An MCP client that supports stdio servers.
  2. Open mrpulor-gh/nuphus-mcp on GitHub and read the README and license.
  3. Install the Rust stable toolchain and build Nuphus MCP from source with Cargo.
  4. Add the Nuphus MCP server to your MCP client as a stdio server.
  5. Let the server open its managed Chrome, go to the target site, and log in once.
  6. Ask the agent to use the browser_* tools to navigate, take a snapshot, and extract the data you need.

These steps come from our top use case, Automate a signed-in website with one saved browser profile, which also has a copy-paste agent prompt.
