Connect a client

Before you start

When your client asks you to sign in, use your Neutron account. The client opens Photon’s sign-in page and brings you back afterward.

In claude.ai, open Customize in the sidebar, then Connectors.
Click +, then Add custom connector.
Enter a name, such as Photon Neutron, and the remote MCP server URL https://ai.neutron.health.
Click Connect and sign in with your Neutron account. The connector shows as active once you’re signed in.

Connectors you add on claude.ai also work in the Claude desktop app.

In chatgpt.com, open Settings, then Apps.
Under Advanced settings, click Create app.
Enter a name, such as Photon Neutron, and the server URL https://ai.neutron.health.
Sign in with your Neutron account.
In a chat, turn on the app before you ask it to prescribe.

claude mcp add --transport http photon https://ai.neutron.health

Then run /mcp in Claude Code to sign in with your Neutron account.

Point any MCP client that supports streamable HTTP at https://ai.neutron.health.

To act for a prescriber, let the client run OAuth. Without a token, the server answers with a 401 challenge that points to its OAuth metadata at /.well-known/oauth-protected-resource, so the client can find the sign-in flow from the URL alone.
To draft from a backend, send a machine token as Authorization: Bearer …. A machine token can take intake, search and draft, but it can’t send. A prescriber sends from Prescribe. See Agent-drafted orders.

Ask for a prescription for a test patient:

Prescribe amlodipine 5 mg, one tablet daily, 30 tablets, for Paige Turner, born 1990-01-01, female.

The agent calls rx_intake, rx_search and rx_draft, then shows you the draft and any screening alerts. It sends only when you confirm.

Assistants can be cautious about clinical requests. Tell yours that you’re working in Photon’s Neutron sandbox with test patients.
