Perplexity

Code with real, structured trial data

Use the `search_clinical_trials` tool to have Cursor's agent query the live database. Ask it to find trials for a specific drug, then tell it to generate a Python function that parses the results. You get working code based on the actual data structure. Stop writing code against stale mock data. With this tool, your agent builds functions using real-world API responses, which cuts down on rework and debugging later.

Get full trial details inside your editor

The `get_trial_details` tool fetches the complete study information for any NCT identifier. If you have an ID in a comment or a variable, just highlight it and ask the agent to 'get details for this trial and create a JSON object'. Cursor will drop the formatted data right where you need it. It’s perfect for quickly scaffolding data models or populating test fixtures without ever leaving your IDE.

Find recruiting studies for your health app

The `find_recruiting_trials` tool is built for finding active studies. While coding a feature, you can ask the agent, 'find recruiting trials for pediatric asthma in New York'. It returns structured data you can use immediately. This MCP server gives your agent direct access to enrollment information. You can build features that show users relevant, joinable trials based on their profile, powered by live data.

Setup guide

Set up ClinicalTrials.gov MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the ClinicalTrials.gov MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent ClinicalTrials.gov transactions." If the MCP tools are loaded correctly, Cursor will call the ClinicalTrials.gov tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "clinicaltrialsgov-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"

Common questions about ClinicalTrials.gov MCP in Cursor

Activate the agent and ask it to find trials using a tool, then tell it what to do with the data. For example: 'Find trials for Ozempic using `search_clinical_trials`, then write a TypeScript interface for the results'.

Yes. Put an NCT ID in your code, highlight it, and tell the agent 'get the details for this trial'. It will use the `get_trial_details` tool and insert the full record as code or a comment.

Just ask the agent directly in chat, like 'find recruiting trials for Parkinson's disease'. Cursor will automatically use the `find_recruiting_trials` tool from this MCP server.

No. The MCP server handles the connection to ClinicalTrials.gov securely. You just install the server in your Cursor config and you're ready to go.

No, nothing is stored. When your agent queries for a condition or NCT ID, the request passes through a stateless Vinkius server to ClinicalTrials.gov. Your search data is never retained.
