## Description

This MCP connects your AI agent straight to the gold standard source for clinical trial transparency: the NIH's ClinicalTrials.gov database. Instead of spending hours navigating complex government websites—manually filtering tabs and cross-referencing dates—your AI client handles it all in real time. You can query vast datasets spanning hundreds of thousands of studies, pinpointing exactly what you need, whether it’s a Phase 3 trial for Alzheimer's or a drug study sponsored by a specific company. The system pulls complete protocols, eligibility criteria, and enrollment status right into your workflow. It doesn't matter if you use Claude, Cursor, or any other compatible client; through Vinkius, you get one connection point to this critical biomedical data source. This MCP is essential for anyone working with advanced medical research.

## Capabilities

### Identify active participant opportunities
Instantly find clinical trials that are currently enrolling participants based on a specific medical condition.

### Pull comprehensive study protocols
Retrieve full, detailed records for any registered trial using its unique NCT identifier.

### Search the entire global registry
Run complex searches across the entire database by keywords, drug name, sponsor, or specific study phase.

## Use Cases

### A patient advocate needs to know what's available for a rare disease.
The agent uses find_recruiting_trials, specifying the rare condition. It returns a list of 8 active trials across different institutions, including their enrollment targets and current status, so the advocate can immediately guide families toward open opportunities.

### A pharma researcher needs to verify competitor data quickly.
The agent uses search_clinical_trials, filtering by a specific drug name and sponsor. It generates a report showing all historical and current trials for that compound across different global sites, which is essential for competitive analysis.

### A clinician needs the full details on a promising trial.
The agent receives an NCT number from a colleague. The user feeds it to get_trial_details, and the MCP returns the complete protocol summary, including exact inclusion/exclusion criteria for immediate patient verification.

### Analyzing all Phase 3 trials related to immunotherapy.
The agent uses search_clinical_trials, setting filters for 'immunotherapy' and 'Phase 3'. It compiles a table listing the top five studies globally, detailing their primary endpoints and recruitment status.

## Benefits

- Pinpoint active participant opportunities: Use find_recruiting_trials to immediately identify studies enrolling people with a specific medical condition, saving weeks of manual searching.
- Deep dive into protocols: get_trial_details pulls the full study protocol for any trial using its NCT ID. You get eligibility rules, intervention details, and sponsor info all in one place.
- Comprehensive search scope: The search_clinical_trials tool lets your agent query over 500k studies by condition, drug name, or even filter results just to see Phase 3 trials.
- Saves time on tedious data collection: Instead of copying and pasting details from multiple NIH pages, the MCP delivers structured, usable data directly to your chat window.
- Supports complex filtering: You can combine criteria—say, 'Alzheimer's *and* Phase 2 *and* drug X—all in one query using search_clinical_trials.

## How It Works

The bottom line is, your AI client pulls massive amounts of public health research data into a clean, usable format without needing any manual API calls or site navigation.

1. You instruct your AI client to search for trial data, specifying criteria like a disease or therapeutic area.
2. The MCP executes the query against the NIH database and filters the results according to your parameters (e.g., Phase 2 trials only).
3. Your agent returns structured data: lists of matching studies, full protocols, or enrollment status reports that you can use immediately.

## Frequently Asked Questions

**How can I use the ClinicalTrials.gov MCP to find trials for a specific disease?**
You tell your AI agent you need to search by condition, like 'Alzheimer's disease.' The system will query all available studies and provide filtering options so you only see relevant phases or drug types.

**Does the ClinicalTrials.gov MCP show me trials that are closed?**
It can. However, if you need to know what's open for participants right now, your agent uses a specific tool to filter out completed or paused studies and only shows active enrollment opportunities.

**What kind of data do I get when I use the ClinicalTrials.gov MCP?**
You receive highly structured biomedical data, including eligibility criteria, sponsor names, intervention details, and recruitment timelines—not just a link to a webpage.

**Is the information from the ClinicalTrials.gov MCP real-time or cached?**
The MCP connects directly to the NIH database, ensuring you get current public data. This means your research reflects the most recent status updates available in the registry.

**Can I use the ClinicalTrials.gov MCP for drug development analysis?**
Yes. You can search by specific drug names or therapeutic areas and filter results to map out which compounds are being tested at various stages, helping you track competitive moves.
