ClinicalTracker.org + Perplexity: when a trial changes, look for coverage and papers with sources

ClinicalTracker.org tells you when a trial or FDA record you follow changes, with links to the official record. Perplexity answers with citations, so you can then look for published coverage and papers about the study and open each source. Information only, not medical advice.

Key takeaways

The short version.

  • ClinicalTracker.org watches ClinicalTrials.gov and openFDA and links every change to the official record.
  • Perplexity answers with citations, which suits the second step: finding coverage and papers about a study after you know what changed.
  • Perplexity's help center describes custom remote connectors that take an HTTPS MCP address, so you can try adding the tracker yourself if your account allows it.
  • The help page does not say which plans include custom connectors, and organization members need an admin to allow them, so check your own account.
  • This is research information, not medical advice. Coverage is not a verdict on a trial, and neither tool judges eligibility or ranks treatments.

It is for people who follow a trial closely and want to read around it: patients and families, patient advocates, journalists, students, researchers and analysts who like to see where a claim comes from.

ClinicalTracker.org watches ClinicalTrials.gov and openFDA, both public U.S. government sources, and tells you, or your AI assistant, when a trial or FDA record changes. Every change links to the official record. Perplexity is an AI answer engine that cites the pages it read.

One tells you what changed in the record. The other helps you find what has been published about the study. This is not an official integration, and AgentStructure has no partnership with Perplexity.

Use cases

4 ways people use ClinicalTracker.org + Perplexity.

  1. Change, then press

    1. See the change first, then look for coverage

    Start with the tracker: what changed in the trials I follow this week? Each change comes with the previous and new values and a link to the registry record.

    Then ask Perplexity what news outlets and medical sites have published about that study. Because it cites its sources, you can open each one and see whether it matches the record or only repeats a headline. Treat the results as leads to read.

  2. Papers

    2. Find papers about a study

    A registry record is not a paper. After results are posted or a status changes, ask Perplexity to find published papers or conference abstracts that mention the trial's NCT number, and to show the link for each.

    ClinicalTracker.org also offers an alert kind for new published papers about a trial. Perplexity is a way to go further, with its own sources for you to open.

  3. Recruiting status

    3. Check how a status change was described

    A trial may move from not recruiting to recruiting, or be suspended. The tracker records the change and links the record. Ask Perplexity how the sponsor or the press described it.

    A registry status of recruiting is not a promise of an open place in a study. Contact the study site listed in the record, and talk to your care team about any trial.

  4. Plain words

    4. Understand a term in a change

    A change may mention a phase, an endpoint or an eligibility rule you have not met before. Ask Perplexity to explain the term and cite where the explanation comes from.

    The tracker does not judge eligibility, rank how well treatments work or predict whether a trial will succeed, and an explanation of a term does not either.

How to

How do I connect ClinicalTracker.org to Perplexity?

  1. Step 1

    Copy the tracker's address from [clinicaltracker.org](https://clinicaltracker.org): https://clinicaltracker.org/mcp for the full tools, which ask you to sign in, or https://clinicaltracker.org/mcp/public for search only.

  2. Step 2

    In Perplexity, open Plugins, or Customize and then Connectors. Per its [help center](https://www.perplexity.ai/help-center/en/articles/13915507-adding-custom-remote-connectors), choose Add custom, then Connector, then Add MCP connector, and select Remote.

  3. Step 3

    Enter a name and the address. It must use HTTPS. Pick an authentication method; the help page lists None, API Key and OAuth 2.0. The full address asks you to sign in, so OAuth is the option to try. Tick the acknowledgement box and click Add.

  4. Step 4

    Click the connector card to authenticate and enable it, then ask what changed in the trials you follow. Open the sources before you rely on any answer.

Perplexity's help page does not say which plans can add custom connectors. Organization members need an admin to allow it, and the page warns that Perplexity cannot verify third-party servers. If you cannot add it, you can still use the tracker's free email alerts and paste the registry links into Perplexity. ClinicalTracker.org is not listed in Perplexity's directory or built into it.

FAQ

Frequently asked questions.

Is ClinicalTracker.org an official Perplexity integration?

No. There is no partnership, listing or built-in integration. Perplexity describes custom remote connectors, and you add the tracker's address yourself if your account allows it.

Is this medical advice?

No. The tracker reports what the official registries say and what changed. It does not judge eligibility, rank treatments or predict whether a trial will succeed. Talk to your care team about any trial.

Does Perplexity decide if coverage about a trial is right?

No. It finds pages and cites them. Open the sources and compare them with the official record, and treat any claim you cannot match to the record with caution.

Where does the trial data come from?

ClinicalTrials.gov and openFDA, both public U.S. government sources. History starts when the tracker first saw a study; earlier versions are on the registry's own history tab.
