Show HN: Proxima – local open-source multi-model MCP server (no API keys) (github.com)

Proxima has launched a local, open-source multi-model server that allows users to interface with several AI models, including ChatGPT, Claude, Gemini, and Perplexity, through a single API endpoint without the need for API keys. This innovative tool simplifies workflows by enabling developers to access various functionalities—such as chatting, searching, coding, and translating—using one URL and a straightforward function setup. By leveraging existing browser sessions, Proxima maintains privacy and user control over data, running entirely on local machines. This development is significant for the AI/ML community as it enhances accessibility and flexibility in utilizing multiple AI models without the typical overhead associated with authentication and API management. The introduction of features like a smart router to optimize model selection for specific queries, along with 27 new multi-channel processing tools, empowers developers to streamline their coding environments. Proxima's REST API compatibility with OpenAI means it can be easily integrated into existing projects, making it a versatile option for both individual programmers and larger development teams.
