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

Continuous Integration

(Replace your-github-username with your actual GitHub username and build-unblocker-mcp with the repository name)

local-only server

The server can only run on the client's local machine because it depends on local resources.

A Model-Context-Protocol server for Cursor IDE that monitors and terminates hung Windows build executables (like cl.exe, link.exe, msbuild.exe) when they become idle.
