How to Set Up and Use YC Killer
YC Killer is an open-source library of enterprise-grade AI agents built by Singularity Research to provide free alternatives to venture-backed AI startups. The collection includes a Deep Research agent (recursive multi-source research with citations), a fully autonomous Agentic Quant Hedge Fund (strategy ideation, alpha engineering, backtesting), a Jarvis executive assistant (calendar, email, web search, OAuth), an AI Hospital for medical triage, an AI Professor for tutoring, an Agentic Accounting Firm integrated with QuickBooks, an AI Call Center, and Nano-Claude-Code (a Rust implementation of a Claude Code-style coding agent). Each sub-agent ships with its own Docker setup and detailed README.
Prerequisites
- Docker and Docker Compose for containerised agents
- Node.js 18+ or Python 3.10+ depending on the agent (each agent varies — check its own README)
- API keys for AI providers used by each agent (e.g. OpenAI GPT-4 for most agents, or Anthropic for Nano-Claude-Code)
- Google OAuth credentials for the Jarvis agent (calendar/email features)
- An MCP-compatible client such as Claude Desktop if using the MCP interface
Clone the main repository
Clone the YC Killer monorepo which contains all agent subdirectories.
git clone https://github.com/sahibzada-allahyar/YC-Killer.git
cd YC-KillerChoose an agent and navigate to its directory
Each agent is a self-contained project with its own dependencies and setup instructions. Pick the one that fits your use case.
# Examples
cd Agentic-Deep-Research
# or
cd Agentic-Quant-Hedge-Fund
# or
cd Jarvis-Agentic-Executive-AgentInstall agent dependencies
Follow the agent-specific README to install dependencies. Most Python agents use pip; Node.js agents use npm.
# Python agents
pip install -r requirements.txt
# Node.js agents
npm installConfigure environment variables
Each agent requires API keys set as environment variables or in a .env file. The most common variable is OPENAI_API_KEY. Check each agent's README for the full list.
export OPENAI_API_KEY=your_key_here
# Additional keys vary by agent, e.g.:
export ANTHROPIC_API_KEY=your_key_hereRun via Docker Compose (recommended) or directly
Most agents ship with Docker support for easy, reproducible deployment.
# Docker (recommended)
docker-compose up --build
# Or run directly (Python example)
python main.pyConnect to Claude Desktop as an MCP server
Register the agent as an MCP server in Claude Desktop's config to access its capabilities from within Claude.

Example prompts matching the capabilities of YC Killer's various agents.
- "Run a deep research report on the current state of quantum computing startups, with citations."
- "Generate a market-neutral trading strategy idea based on momentum and mean-reversion principles."
- "Schedule a meeting with the team for next Tuesday at 3pm and send calendar invites via Jarvis."
- "Review this patient's symptoms and suggest which specialist they should see."Troubleshooting YC Killer
Docker build fails due to missing dependencies
Ensure Docker Desktop is running and up to date. Run docker-compose up --build from within the specific agent's subdirectory (not the repo root), as each agent has its own docker-compose.yml and Dockerfile.
API calls fail with authentication errors
Each agent has its own set of required environment variables. Copy the example .env file (cp .env.example .env) and fill in all required keys. The Deep Research agent needs OPENAI_API_KEY; the Jarvis agent also needs Google OAuth credentials configured in the Google Cloud Console.
Nano-Claude-Code Rust binary fails to compile
Nano-Claude-Code requires a recent Rust toolchain. Install or update via rustup (curl https://sh.rustup.rs -sSf | sh), then run cargo build --release from the Nano-Claude-Code directory.
