Prompt Opinion offers a platform that turns standalone healthcare AI agents into full workflows. Instead of scattered pilots that never leave the lab, it hooks agents up to your EHR, policies and data, then stitches them together into real-world tasks. Builders write the AI logic, organizations supply charts and rules, and the platform uses open specs—MCP for tools, A2A for agent-to-agent calls, FHIR for data—to keep everything interoperable. You can start from templates, write native agents in the system, pull in third-party bots from the registry or tap into reusable MCP tools like clinical calculators or coding lookups. Once assembled, these workflows handle things like generating prior-auth packets, matching patients to trials, spotting care gaps across populations, summarizing charts or drafting policy-aligned guidance. Every agent adapts its output to the context—one patient at the bedside, a cohort for population health, or research criteria for trial matching. Prompt Opinion serves two audiences. Builders—clinicians, informaticists and engineers—get reference code in TypeScript and Python, plus infrastructure to publish agents once and reach every customer. Healthcare organizations get turnkey agents connected to their EHR from day one, complete with governance, audit trails and compliance. Now live in beta, the Agents Assemble Challenge invites developers to build and publish AI agents that deliver concrete outputs—a document, table, transaction, consultation or task—ready for production use.
