Juno Open Health Tools MCP Server

Juno Open Health Tools

Free, privacy-conscious tools for turning messy symptom notes into a clearer appointment conversation.

This repository includes:

• an open JSON Schema and CSV format for a portable symptom diary;
• synthetic examples (no real patient data);
• an importable Notion appointment-preparation workspace;
• a printable, Canva-importable appointment-preparation pack;
• a local-first Chrome/Edge appointment-prep extension;
• a Juno Health Tools MCP app for ChatGPT and Codex;
• a combined four-skill and five-tool OpenAI plugin package with explicit consent and privacy boundaries;
• methods and citation guidance for researchers and patient organisations.

Safety and privacy

These materials help people organise information. They do not diagnose, recommend treatment, replace a clinician, or provide emergency care. The examples are synthetic. The MCP tools process submitted text in memory and do not intentionally persist it. Avoid adding information you would not want handled by the service or workspace where you use a template.

If symptoms may be urgent or life-threatening, contact local emergency services or an appropriate clinician.

Quick starts

Notion

Duplicate the free public Juno Appointment Prep template, or import the files in templates/notion into a new private Notion page.

Printable / Canva

Use the PDF in output/pdf/ as-is, or upload the layered PowerPoint in templates/canva to Canva for a more editable personal copy. The source generators are in scripts/.

Chrome / Edge extension

Use the source in extension, or download the store-ready ZIP from the latest GitHub release. It saves short changes, timeline points, daily-life impacts, and questions in local browser storage, then creates a copyable appointment plan. It makes no remote requests and requires only the browser storage permission.

MCP app

Try the public Juno Health Tools app, or read the endpoint documentation in app/README.md. Local development:

cd app
npm install
npm test
npm run dev

The public plugin source is in plugins/juno-health-tools, with submission and reviewer materials in submissions/openai-plugin-2026.md.

The remote server is published as io.github.MarshallBear1/juno-open-health-tools in the official MCP Registry.

Research and charity collaboration

The three-page Action for M.E. / PRIME concept note proposes a governance-first, co-authored public data brief about appointment communication for people with ME/CFS. It is a discussion document, not a research protocol or recruitment notice; no participant data has been collected.

Open symptom diary standard

The schema is intentionally small and patient-controlled. It captures observations rather than asserting diagnoses or causal relationships. See schema/README.md.
