Frequently asked questions
Do I need an API key?
No. ClinicalTrials.gov is completely free and public. No authentication required.
What are clinical trial phases?
Phase 1 tests safety in small groups; Phase 2 evaluates efficacy; Phase 3 confirms effectiveness in large populations; Phase 4 monitors post-approval. Each phase provides progressively stronger evidence.
Can patients find trials to enroll in?
Yes. Use the recruiting filter to find trials currently accepting participants. You can filter by condition, location, and eligibility criteria to find accessible trials.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
