mcp-agent-graph provides a graph-based orchestration layer for AI agents, enabling developers to map out complex multi-step workflows as directed graphs. Each node in the graph corresponds to an agent task or function, capturing inputs, outputs, and dependencies. Edges define the flow of data between agents, ensuring correct execution order. The engine supports sequential and parallel execution modes, automatic dependency resolution, and integrates with custom Python functions or external services. Built-in visualization allows users to inspect graph topology and debug workflows. This framework streamlines the development of modular, scalable multi-agent systems for data processing, natural language workflows, or combined AI model pipelines.
