Is it safe to check my password using this tool?

Yes. This agent uses the K-Anonymity model. Only the first 5 characters of your password's SHA-1 hash are sent to the HIBP server. The full password or full hash never leaves your local environment, making it cryptographically safe.

Where can I get an API Key?

You can purchase an API key directly from the [HIBP website](https://haveibeenpwned.com/API/Key). It requires a small monthly subscription to prevent mass scraping and abuse.

Have I Been Pwned + Pydantic AI FAQ

Common questions about integrating Have I Been Pwned MCP Server with Pydantic AI.

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 Have I Been Pwned MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
