Overview

What is Heym?

Heym is a self-hosted, source-available AI workflow automation platform built around LLMs, agents, and intelligent tooling. Wire together AI agents, vector stores, web scrapers, HTTP calls, and message queues on a visual canvas — then deploy instantly via Docker.

MCP Support

Heym supports the Model Context Protocol (MCP) in two directions:

As a client: Agent nodes connect to any external MCP server and gain all its tools automatically.
As a server: Your Heym workflows are exposed as an MCP server at /api/mcp/sse — callable from Claude Desktop, Cursor, or any MCP client.

Quick Start

git clone https://github.com/heymrun/heym.git
cd heym
cp .env.example .env
./run.sh

Then open the editor at http://localhost:4017.

MCP Server Config

Add this to your MCP client configuration:

{
  "mcpServers": {
    "heym": {
      "url": "http://localhost:4017/api/mcp/sse"
    }
  }
}

Songcheck Ai Music Detector

@afghanfansmedia-ai

Is this song AI or human? SongCheck detects AI-generated music (Suno, Udio, and more) and media from any AI agent. Point it at an audio file, an image/video, or a whole music folder and it returns a verdict (LIKELY AI-GENERATED / UNCERTAIN / LIKELY HUMAN), an AI-probability score, confidence, and provenance signals (Content Credentials / SynthID watermark, generator hints). Tools: detect_ai_music, detect_ai_media, scan_catalog (audit an entire catalog), and songcheck_health. Free tier is 5 checks/day; a paid key unlocks unlimited catalog scans. Powered by SongCheck (Khaled Media), a self-hosted v9 ensemble detector.
