Impact Preview MCP

An MCP server that acts as a safety layer for autonomous AI agents by intercepting proposed actions, analyzing their impact, and showing a diff preview before execution. It provides tools to preview file writes, file deletions, and shell commands, along with risk assessment and an approval workflow to prevent accidental changes to production environments.
