LangGraph MCP leverages directed acyclic graphs to represent sequences of LLM calls, allowing developers to break down tasks into nodes with configurable prompts, inputs, and outputs. Each node corresponds to an LLM invocation or a data transformation, facilitating parameterized execution, conditional branching, and iterative loops. Users can serialize graphs in JSON/YAML format, version control workflows, and visualize execution paths. The framework supports integration with multiple LLM providers, custom prompt templates, and plugin hooks for preprocessing, postprocessing, and error handling. LangGraph MCP provides CLI tools and a Python SDK to load, execute, and monitor graph-based agent pipelines, ideal for automation, report generation, conversational flows, and decision support systems.

LLMFlow provides a declarative way to design, test, and deploy complex language model workflows. Developers create Nodes which represent prompts or actions, then chain them into Flows that can branch based on conditions or external tool outputs. Built-in memory management tracks context between steps, while adapters enable seamless integration with OpenAI, Hugging Face, and others. Extend functionality via plugins for custom tools or data sources. Execute Flows locally, in containers, or as serverless functions. Use cases include creating conversational agents, automated report generation, and data extraction pipelines—all with transparent execution and logging.
