Open MCP Client is a web application with a frontend UI and a separate agent service that handles core functionality. It requires OpenAI and LangSmith API keys, with the agent's dependencies managed through Poetry, and runs locally on port 3000. It suits developers who want to run and inspect an MCP client stack locally, launching the frontend and agent separately for debugging or together with a single command.
