Ocular Optokinetic Nystagmus (OKN) MCP Server
Provides OKN gain, retinal slip, and visual-motion sickness scoring to support Hermes personal agent UI animation moderation and visual stabilization.
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
Ocular Optokinetic Nystagmus (OKN) Skill
Zero-dependency sovereign personal agent skill for non-invasive evaluation of Optokinetic Nystagmus (OKN) slow-phase velocity gain, retinal slip velocity, and visual-vestibular motion stabilization.
