How to Use the Harvard ClinicalTrials MCP in Cursor

Q: How do I link Harvard ClinicalTrials to my project in Cursor?

Create a .cursor/mcp.json file in your root folder. Define the server path there, and the agent will be able to invoke the tools during your next coding session.

Q: What if I need to update my Harvard ClinicalTrials tools in Cursor?

Edit your mcp.json file to update the server configuration. The changes take effect as soon as you save and trigger the agent to re-scan the available tools.

Perplexity

Build apps using Harvard ClinicalTrials data

Use `search_studies` in Agent mode to pull live records into your editor. You write code that interacts with real medical data instead of relying on fake local stubs. This connects your logic to the actual database. You see the schema of the trial records immediately, which makes building your data pipeline much faster.

Automate trial filtering in Cursor

Call `search_by_phase` or `search_by_sponsor` to filter large sets of trials during your build process. The agent writes the code to handle these responses automatically. Stop guessing how the API handles complex inputs. By calling these tools directly, your code consumes the exact response format returned by the clinical database.

Verify trial status in production

Use `get_study_timeline` to check if your clinical data is outdated. The agent can verify the last update timestamp before it processes the study details. This ensures your application logic accounts for the current state of a trial. It removes the risk of building on top of stale or canceled study information.
