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.

OmniSteward is a modular AI agent orchestration platform built on Python that connects to OpenAI, local LLMs, and supports custom models. It provides memory modules to store context, toolkits for API calls, web search, code execution, and database queries. Users define agent templates with prompts, workflows, and triggers. The framework orchestrates multiple agents in parallel, manages conversation history, and automates tasks via pipelines. It also includes logging, monitoring dashboards, plugin architecture, and integration with third-party services. OmniSteward simplifies creating domain-specific assistants for research, operations, marketing, and more, offering flexibility, scalability, and open-source transparency for enterprises and developers.

ThreeAgents is built in Python, leveraging OpenAI's chat completions API to instantiate multiple AI agents with distinct roles (system, assistant, user). It provides abstractions for agent prompting, role-based message handling, and context memory management. Developers can define custom prompt templates, configure agent personalities, and chain interactions to simulate realistic dialogues or task-oriented workflows. The framework handles message passing, context window management, and logging, enabling experiments in collaborative decision-making or hierarchical task decomposition. With support for environment variables and modular agents, ThreeAgents allows seamless swapping between OpenAI and local LLM backends, facilitating rapid prototyping of multi-agent AI systems. It ships with example scripts and Docker support for quick setup.
