Agentic Developer MCP is a server built on OpenAI's Codex that connects to AI clients via MCP and recursively to itself, enabling a workbench development paradigm. This paradigm positions the developer as a team lead managing AI agents to write code in a structured and controlled manner. The server leverages OpenAI's Responses API, and supports both local and hosted models, providing developers with complete control and privacy. The workbench approach allows for tailored environments, improving the accuracy and consistency of code generation.
