About OHarness

OHarness is a transparent agent harness that runs an AI assistant for work on your local computer. You control the context, memory, models, tools and permissions: it speaks natively to Anthropic, OpenAI and Gemini plus any OpenAI-compatible endpoint or local models via Ollama and LM Studio, with built-in tool calling, an MCP client, subagents in isolated contexts, and sessions, memory and credentials kept in readable files on your machine across desktop, browser and CLI frontends.
