Callout

Callout is an open-source Model Context Protocol (MCP) server designed to provide automated multi-perspective reviews and coaching for software development projects. It integrates with AI code assistants like Claude Code, Cursor, VS Code, and Windsurf, offering 9 expert perspectives (technical, business, founder) to catch over-engineering and blind spots. Callout delivers architecture reviews, idea validation, habit coaching, compliance enforcement, tool recommendations, and plain-language test result translations—helping developers prioritize the right work and improve code/project quality without extra API costs.
