Integrate ClinicalTrials.gov API to search clinical trials by condition, intervention, or location, with detailed study
Connects to ClinicalTrials.gov's database to search and retrieve clinical trial information by condition, location, status, and study ID. Includes data cleaning and local backup storage.
ClinicalTrials.gov is a community-built MCP server published by cyanheads that provides AI assistants with tools and capabilities via the Model Context Protocol. Integrate ClinicalTrials.gov API to search clinical trials by condition, intervention, or location, with detailed study It is categorized under databases, analytics data.
You can install ClinicalTrials.gov in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport.
Apache-2.0
ClinicalTrials.gov is released under the Apache-2.0 license. This is a permissive open-source license, meaning you can freely use, modify, and distribute the software.
Enable Claude to query your database directly using natural language
Example
Ask 'Show me top 10 customers by revenue this month' and get SQL results instantly
Eliminate manual SQL writing for ad-hoc queries, get insights 10x faster
Generate complex reports and analytics without leaving conversation
Example
Analyze sales trends, cohort retention, user behavior patterns conversationally
Democratize data access—non-technical team members can query databases
Understand database structure, relationships, and data models
Example
'Explain the user_orders table schema and its relationships'
Onboard engineers faster, explore unfamiliar databases efficiently

ClinicalTrials.gov has been reliable for tool-calling workflows; the MCP profile page is a good permalink for internal docs.
ClinicalTrials.gov is among the better-indexed MCP projects we tried; the explainx.ai summary tracks the official description.
I recommend ClinicalTrials.gov for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.
We evaluated ClinicalTrials.gov against two servers with overlapping tools; this profile had the clearer scope statement.
According to our notes, ClinicalTrials.gov benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.

💡 Pro Tips
Architecture
MCP server acts as bridge between Claude and database, translating natural language to SQL queries and returning results in structured format.
Protocols
Compatibility
✓ Use when
Use for ad-hoc data queries, exploratory analysis, report generation, schema exploration, and democratizing data access. Best for read-heavy analytics workloads.
✗ Avoid when
Avoid for production write operations, mission-critical transactions, real-time OLTP workloads, or when database contains sensitive PII without proper access controls. Use read replicas, not primary.
