Uag

Form.io's UAG brings their JSON schema forms into the MCP world, giving AI agents the same structured understanding of forms that their JavaScript renderer gives humans. You get two main tools: one converts natural language into validated form submissions, the other lets agents analyze existing submission data and contribute their own fields based on configurable criteria. Think automating college application reviews where an agent reads a student's essay and academics, then fills out an evaluation form following your rubric. The criteria lives in special content components with a uag property, agent fields get tagged with matching personas, and the whole thing works with their open source platform. Best for workflows where you need AI to both understand and contribute to structured data collection processes.
