CLIO Spack

Overview

CLIO Spack is a Model Context Protocol server that provides structured discovery and installation tools for the Spack package manager, designed to support scientific computing workflows and AI agents. It exposes Spack operations as callable tools, allowing AI assistants to automate package discovery and installation without manual intervention.

The server runs locally on your machine via the Python package clio-kit, installed through uvx clio-kit. It communicates with MCP clients over stdio and requires no authentication or external credentials. The latest release is v2.1.0, distributed under the BSD-3-Clause license with source code available at iowarp/clio-kit on GitHub, which has 26 stars.

CLIO Spack is listed in the AI & Agents category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, you can claim this listing to verify ownership and keep the information up to date.
