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.

Graphium is a knowledge graph and LLM orchestration framework that supports ingestion of structured data, creation of semantic embeddings, and hybrid retrieval for Q&A and chat. It integrates with popular LLMs, graph databases, and vector stores to enable explainable, graph-powered AI agents. Users can visualize graph structures, query relationships, and employ multi-hop reasoning. It provides RESTful APIs, SDKs, and a web UI for managing pipelines, monitoring queries, and customizing prompts, making it ideal for enterprise knowledge management and research applications.

Geers AI Lang Graph provides a graph-based abstraction layer for building AI agents that coordinate multiple LLM calls and manage structured knowledge. By defining nodes and edges representing prompts, data, and memory, developers can create dynamic workflows, track context across interactions, and visualize execution flows. The framework supports plugin integrations for various LLM providers, custom prompt templating, and exportable graphs. It simplifies iterative agent design, improves context retention, and accelerates prototyping of conversational assistants, decision-support bots, and research pipelines.
