marklayer-mcp
Advanced tools
MCP (Model Context Protocol) server that bridges MarkLayer annotations to AI coding agents.
When users annotate any webpage with MarkLayer, your agent receives the comments as a structured work queue: it can acknowledge, resolve, dismiss, and reply to each one — and the human sees the status updates live.
# Add to Claude Code:
claude mcp add marklayer -- npx -y marklayer-mcp
# Or pre-connect to a specific room:
claude mcp add marklayer -- npx -y marklayer-mcp --room https://marklayer.app/s/abc123
In your agent prompt:
Watch my MarkLayer annotations. For each one, acknowledge it, make the fix, then resolve it with a summary.
The agent will call marklayer_watch_annotations in a loop and process incoming feedback as it arrives.

The compromise affects MemTensor's MemOS, an open source memory framework for large language models (LLMs) and AI agents. Both npm package @memtensor/memos-cloud-openclaw-plugin and the PyPI package MemoryOS are compromised. They drop cross-platform Go binaries that exfiltrate developer secrets.
