Show HN: Lumae Native macOS screen-demo recorder that agents can edit over MCP

Lumae is a native macOS screen-demo recorder that integrates with the Model Context Protocol (MCP), enabling AI agents to edit recordings programmatically. The tool was announced on Hacker News as a Show HN submission, allowing builders to record screen interactions and grant agents structured access to edit and refine those recordings via MCP.

The recorder captures macOS screen activity and stores it in a format that agents can parse and modify through MCP—a standardization effort that lets large language models and autonomous systems interact with applications and services through a common protocol. This approach addresses a workflow gap: typically, screen recordings are static artifacts that require manual editing or re-recording if changes are needed. Lumae flips that by making recordings into editable, agent-friendly data.

The specific feature set and pricing details remain minimal in the initial Show HN post, which received 2 points and 2 comments at the time of posting. The announcement links to lumae.app for further information on the product and its capabilities.

Screen recording is a common task in demo creation, tutorial production, and bug reporting. By making recordings editable by agents over MCP, Lumae targets workflows where developers or content creators need programmatic control over captured footage—trimming, re-narrating, or extracting segments without re-recording. The MCP integration means the tool fits into broader AI-agent toolchains rather than standing alone as a simple recorder.
