Mark Layer MCP Server

Website feedback your AI agent can act on. Draw, highlight, and comment on any live webpage, then share one link. A human reviews it in real time, or an AI agent connects over MCP and works it like a to-do list: acknowledge, fix, resolve, reply. It runs locally over stdio via the published package.

People who work with annotation, browser extension and bug tracking and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
