Build Unblocker MCP

Build Unblocker MCP

A Model-Context-Protocol (MCP) server for Cursor IDE to terminate hung Windows build executables.

Features

  • Monitors specified build processes (cl.exe, link.exe, msbuild.exe, etc.)

  • Terminates processes that are idle (less than 1% CPU usage) for a configurable duration (default 90 seconds)

  • Provides a tool (unblock_build) for Cursor IDE to trigger the unblocking process

Installation

  1. Ensure you have Python 3.11 or later installed.

  2. Install using pipx (recommended for CLI tools):

    pipx install .

    Or using pip:

    pip install .

Cursor Integration

Add the following to your Cursor IDE settings (settings.json):

{
  "mcpServers": {
    "build-unblocker": {
      "command": "unblock-build-mcp"
    }
  }
}

Local Smoke Test

You can run the tool manually to test it (use --dry-run to avoid killing processes):

pipx run unblock-build-mcp --idle-seconds 5 --dry-run
