What you can do with Photon Health in Claude and ChatGPT
For clinic prescribers and staff who set up e-prescribing with Photon Health.
Find pharmacies by name or near a location
The AI searches pharmacies by name, or near a latitude and longitude within a radius in miles, for pick-up or mail order. It returns NPI, NCPDP, address, phone and fax.
Look up a medication, its products and package codes
The AI searches the medication database by drug name or by RxCUI, NDC or SKU. It then lists the strengths and forms, the packages and the NDC codes.
Review your treatment catalogs and prescription templates
The AI lists the organization's catalogs and reads one with its treatments and templates: quantity, refills, days supply and directions.
Review users, organization, equipment and dispense units
The AI reads the organization details and lists its users with name, NPI, credentials and roles. It can also search prescribable equipment and list dispense units.
How do I connect Photon Health?
Before you connect
Patient data: Do not use this server with protected health information (PHI). We do not sign HIPAA Business Associate Agreements (BAAs). See Terms, Health data.
The login page asks for your Client ID, Client secret and Environment.
Find the key pair in the Photon app → Settings (app.photon.health for production, app.neutron.health for the Neutron sandbox). Sandbox keys only work with Sandbox, production keys only with Production. Your credentials are used only to call the Photon API on your behalf and to derive a private account id; they are never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"photon-health": {
"url": "https://photon-health.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"photon-health": {
"type": "http",
"url": "https://photon-health.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Client ID, Client secret and Environment. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper organization | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per organization | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Photon Health server only. Ask your AI to run photonhealth_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with photonhealth_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with photonhealth_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
photonhealth_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
photonhealth_request_featureTell usefulapi that the user needs something the Photon Health tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. - Upgrade to Pro or Pro+
photonhealth_upgradeGet a paid plan for Photon Health (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
photonhealth_cancel_subscriptionCancel the caller's Photon Health Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run photonhealth_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Photon Health in Claude or ChatGPT?
Find pharmacies by name or near a location. Look up a medication, its products and package codes. Review your treatment catalogs and prescription templates. Review users, organization, equipment and dispense units. See what you can do for the details.
Is this an official Photon Health product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Photon Health. The server calls the Photon Health API with your own Photon Health access, so it sees only the data that your account can see.
Can I use this server with patient data (PHI)?
No. Do not use this server with protected health information (PHI). We do not sign HIPAA Business Associate Agreements (BAAs). See Terms, Health data.
Can I connect Photon Health to Claude or ChatGPT?
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
What do I need to connect?
The login page asks for your Client ID, Client secret and Environment. See Before you connect for where to find them.
Do I put my Photon Health key or an Authorization header in the client config?
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Client ID, Client secret and Environment. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
How do you keep my Photon Health credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Photon Health API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Photon Health.
Can the AI change my Photon Health data?
All 21 Photon Health tools are marked read-only.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Photon Health server only. Cancel any time: your paid plan then runs to the end of the paid period. Run photonhealth_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run photonhealth_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run photonhealth_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Photon Health tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with photonhealth_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Which AI clients can I use?
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
