Every tool call from Pydantic AI to the Harvard ClinicalTrials MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Harvard ClinicalTrials MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
