The Harmonic Endpoint Agent identifies every native AI app, AI-first IDE, CLI tool, locally hosted model and direct inference API call running on employee devices. The Harmonic Endpoint Agent detects Claude Desktop, Claude Code, Claude Cowork and OpenAI Codex on macOS and Windows.

Harmonic Usage Intelligence groups prompts, files, responses, and supported agent actions into coherent tasks and organization-specific use cases, with views by department, employee, application, approval status, and time. Harmonic builds an inventory of the AI apps a workforce uses, who uses them and for what work. Harmonic records which tools are approved, how policy was applied, what was coached or blocked, and where sensitive data was exposed. Harmonic offers configurable retention, role-based access, employee masking and EU or US hosting. Harmonic does not train on customer data.[5][8][9]
