Perplexity

Add Triangle as a custom remote MCP connector in Perplexity. Create a confidential OAuth app, authorize through your Triangle account, then ask Perplexity to use your approved health topics, notes, and records.

Perplexity documentation

Before you start

  • A Triangle account with an active patient profile.
  • A Perplexity Pro, Max, or Enterprise plan. Custom remote MCP connectors are not available on the Free plan.
  • A confidential OAuth app created in the Triangle developer portal, with Perplexity’s OAuth callback registered.

Connection details

What to enter if Perplexity asks for them.

Scopes
Not configured in the connector — permissions are granted on Triangle’s OAuth consent screen when you authorize.

Set it up

  1. Create OAuth credentials for Perplexity

    Perplexity’s custom connector form asks for a Client ID and Client Secret. Create a confidential OAuth app in the Triangle developer portal first.

    • Open https://app.trianglehealth.com/developer/apps and click Create app.
    • Set the display name to Perplexity (shown on the Triangle consent screen).
    • Choose Confidential client (Client ID + Client Secret).
    • Add https://www.perplexity.ai/rest/connections/oauth_callback as a redirect URI base.
    • Save the app, then copy the Client ID and the one-time Client Secret. Store the secret securely because Triangle will not show it again.

  2. Select + Add custom connector

    Custom MCP connectors live under Perplexity Connectors. Open the add menu and choose Add custom connector.

    • Open Perplexity on the web at https://www.perplexity.ai/.
    • Open your profile menu, then Account Settings (or All settings).
    • Select Connectors.
    • Click + Add custom connector, then choose + Add custom connector from the menu.

  3. Provide MCP URL, Client ID, and Client Secret

    Point the connector at Triangle’s MCP URL and paste the OAuth credentials from your confidential Triangle app.

    • Enter a name such as Triangle Health.
    • Optionally add a short description and upload an icon.
    • Set the MCP server URL to https://app.trianglehealth.com/mcp.
    • Open Advanced and set Authentication to OAuth.
    • Paste Your Client Id and Your Client Secret from the Triangle developer portal.
    • Click Add.

  4. Connect and complete the login consent flow

    Authenticate the connector so Perplexity can call Triangle tools with your approved permissions. When finished, Triangle appears under Connected.

    • Click Connect on the Triangle Health connector if Perplexity does not start OAuth automatically.
    • Sign in to Triangle when prompted.
    • Review permissions on the consent screen and click Accept.
    • New users complete the short setup flow (name, agreements, patient profile) before consent.
    • Return to Perplexity Connectors → Connected and confirm Triangle Health shows with a connected status.
    • You can revoke access anytime from https://app.trianglehealth.com → Settings → AI Services.

  5. Talk to Perplexity about your health

    Enable the Triangle connector for the conversation, then ask Perplexity to review records, research conditions, or work with your notes.

    • Start a new thread in Perplexity.
    • Select or enable the Triangle Health connector for that thread if Perplexity requires per-conversation selection.
    • Try prompts such as “Please check my health notes,” “Using Triangle, list my health topics,” or “Summarize my recent Triangle medical records.”
    • Approve any connector prompts Perplexity shows before tool use.
    • Manage or revoke the connection anytime from Settings → AI Services in the Triangle app.

What you can do

  • Browse and organize health topics on your Triangle profile.
  • Read and create notes attached to topics.
  • Search notes across topics.
  • List medical records and read summaries or extracted content (requires medical_records:read consent).
  • Use data tools such as get_topics and get_topic_notes — ChatGPT-style inline widgets are not available in Perplexity.
  • OAuth through a confidential developer portal app (Client ID and Client Secret) plus Perplexity’s custom connector flow.
  • Manage connections anytime from Settings → AI Services in the Triangle app.

Troubleshooting

I do not see Add custom connector in Perplexity

Custom remote connectors require Perplexity Pro, Max, or Enterprise — they are not available on Free. Upgrade, then look for + Add custom connector on Settings → Connectors. Enterprise members may also need an admin to allow custom connectors.

Connector fails to add or tools do not load

Confirm the MCP URL is exactly https://app.trianglehealth.com/mcp, Authentication is OAuth, and you pasted the Client ID and Client Secret from a confidential Triangle app. Remove the connector, add it again, and complete Triangle consent without closing the browser tab early.

OAuth never opens or authorization fails

Confirm your confidential app registers https://www.perplexity.ai/rest/connections/oauth_callback as a redirect URI base, and that the Client ID and Client Secret match that app. Open the Triangle connector card from Settings → Connectors and click Connect again. If it still fails, tell us what Perplexity shows so we can update this guide.

Perplexity does not use Triangle in chat

Enable the Triangle Health connector for the current thread if your plan requires it, then ask explicitly to use Triangle. Retry with a new thread after confirming the connector shows under Connected.

A Triangle tool returns an authorization error

The tool may require a permission you did not grant. Disconnect Perplexity from Triangle Settings → AI Services, reconnect from Perplexity Connectors, and approve the needed permission on the consent screen.

How do I revoke Perplexity access?

Go to Settings → AI Services at https://app.trianglehealth.com and click Disconnect next to the Perplexity connection. Access is revoked immediately. You can also remove the connector from Perplexity Settings → Connectors.
