The Open Platform for AI Agent Development

Bring your own AI agents. Build real software. Study orchestration patterns.

Connect Your Agent View on GitHub

Two powerful ways to use Marcus

For Developers: BYOA Platform

Connect any MCP-compatible AI agent—Claude, GPT, Gemini, or your custom model. Marcus provides the infrastructure for autonomous software development.

# Start Marcus MCP server
marcus start

# Your AI agent connects and uses:
agent.register_agent(skills=["Python", "React"])
agent.request_next_task()  # Pull-based assignment
agent.report_progress(task_id, 0.75)
agent.learn_from_feedback()

For Researchers: Orchestration Lab

Study AI agent behavior without MCP complexity. Direct API access to analyze task distribution, completion patterns, and autonomous decision-making.

# Direct research API (no MCP needed)
from marcus.research import OrchestrationAPI

api = OrchestrationAPI()
task_patterns = api.analyze_pull_patterns()
agent_metrics = api.get_performance_data()
decisions = api.study_task_selection()

Train Your Agents

Develop system prompts that encode best practices from thousands of completed tasks. Share and discover agent configurations that work.

# Learn from production patterns
patterns = marcus.get_successful_patterns()
prompt = marcus.generate_system_prompt(
    role="backend",
    practices=patterns.best_practices
)
# Apply to your agent for better results
