kill-process-mcp is a cross-platform MCP server exposing tools to list and kill OS processes via natural language queries. It provides two core tools: process_list, which lists running processes ordered by CPU or memory with optional filters such as name, user, status, CPU/memory thresholds, system-process filtering, and supports sort order and limit, and process_kill, which terminates the selected process (with extreme prejudice!). The server is designed to work with MCP-compatible LLM clients like Claude Desktop or Cursor and runs on macOS/Windows/Linux with Python 3.13+ and the uv runtime, relying on the mcp and psutil libraries. Installation supports two modes: the preferred uvx workflow with no cloning, or a manual clone-based setup. The README provides configuration examples to register the server with Claude Desktop and Cursor, including uvx and manual mode JSON snippets, and guidance for upgrading and troubleshooting. There are safety notes and an emphasis on practical process management, plus an optional persistent shim for faster startup. Overall, kill-process-mcp enables natural language-driven discovery and termination of system processes for proactive maintenance.
