open-compute-mcp

npm launcher for the Python open-compute MCP server. It forwards MCP JSON-RPC over local stdin/stdout. Real screen capture and input require an interactive Windows desktop on the MCP client's host. No Glama or other hosted/cloud desktop deployment is provided.

This short entrypoint replaces the long-form README.md at predecessor commit 59cd953. The corrected detailed guide is archived here, retaining the former section anchors and diagrams. It is a corrected copy, not an unchanged historical snapshot; the original remains available at the commit link.

Install and run

Requires Node.js 18 or newer and uv. The backend requires Python 3.10 or newer; uvx can use a compatible installed interpreter or download and manage one when needed. The default launch fetches the Python server from GitHub at the master branch; set OPEN_COMPUTE_GIT_REF to choose a branch, tag, or commit. These bootstrap steps require network access.

Add this server to a local MCP client:

{
  "mcpServers": {
    "open-compute": {
      "command": "npx",
      "args": ["-y", "open-compute-mcp"]
    }
  }
}

The npm package is published separately from this Git repository; check its published version for a particular source revision. A direct uvx configuration is in the detailed quick start.

What the launcher does

It starts the Python MCP server and forwards stdio. The wrapper does not implement a network filter, sandbox, privilege drop, or environment scrubber. The child inherits the launcher's environment and operating-system privileges.

The default uvx command retrieves the Python project from GitHub; npm installation contacts npm. In an interactive terminal, the optional update notice may check npm. Local stdio describes the client-to-wrapper transport; it does not block network access by the child or MCP client. The client controls routing of tool results, including screenshots.

For real capture and input, run the MCP client on the Windows desktop to be controlled. Action modes and targeting belong to the Python server; configure the client's approval controls. This wrapper is not an operating-system security boundary.

Tools and configuration

The tool reference is a snapshot of the separate Python project's tool list at a documented source ref. The running server's schemas define the available tools for the selected ref. See also the environment variables.

Related integration

The Cowork Protocol Desktop Companion includes an optional, human-started computer-use adapter that launches the separate Python Open Compute MCP server over local stdio. Its documented default uses uvx; this npm launcher is not a Cowork dependency. This relationship does not change the process, network, or privilege boundaries described above.

Documentation

The repository source manifest currently declares 0.1.0-alpha.20. This documentation work changes no version and publishes no release.

Installation

Source-derived launch command. Check the maintainer’s required arguments and credentials before running:

bash
npx -y open-compute-mcp

Set up in your AI client

Merge this template into ~/Library/Application Support/Claude/claude_desktop_config.json. Keep existing servers. Add any arguments, credentials, and permissions required by the maintainer; this template has not been install-tested.

json

  "mcpServers": {

      "command": "npx",
      "args": [
        "-y",
        "open-compute-mcp"
      ]
    }
  }
}

Restart Claude Desktop completely for changes to take effect. Confirm the server appears connected in the client’s tool list, then try a read-only example from its documentation.
