Greenlight

Visual status indicator that displays colored terminal backgrounds to signal AI work progress states

Greenlight provides visual feedback for AI assistant work status through full-screen colored terminal displays. The server offers tools for AI assistants to signal their current state (working, waiting for approval, or done) which triggers color changes in a companion display application - green when working, yellow when waiting, and red when complete. The implementation uses file-based communication with PID tracking to coordinate between the MCP server and display components, making it useful for developers who want immediate visual confirmation of task status without monitoring logs or terminal output.
