Etan Heyman

AI Infrastructure Engineer. Building open-source tools for AI coding agents.


Golems — MCP servers for the agentic IDE era

Three open-source MCP servers. 44 tools. Works with Claude Code, Codex, Gemini, Cursor, and Kiro.

Project What it does Install
BrainLayer Persistent memory for AI agents — knowledge graph, hybrid search, 12 MCP tools pip install brainlayer
VoiceLayer Voice I/O for AI agents — local STT via whisper.cpp, neural TTS, 10 MCP tools npm i voicelayer-mcp
cmuxLayer Terminal orchestration — spawn panes, read screens, coordinate agents, 22 MCP tools npm i -g cmuxlayer

Each ships with a native macOS companion: BrainBar (menu bar memory dashboard) and VoiceBar (always-on voice interface).

Built on the Golems agent ecosystem — 55+ skills, autonomous coding loop, 6 MCP servers.
