Frequently asked questions
How do I get my Hunter.io API key?
Log in to your Hunter.io account at hunter.io. In the left sidebar, click the API section (or go directly to hunter.io/api-keys). Your API key is displayed on this page. Click the copy button to copy it. Paste it into the configuration field below. Free plans include 25 searches and 50 verifications per month.
Can I find the email of a specific person at a company?
Yes. Give your AI agent a person's first name, last name, and company domain, and it returns their most likely professional email address with a confidence score. Perfect for reaching out to specific decision-makers.
How accurate is the email verification?
Hunter's verification checks MX records, SMTP responses, and catch-all configurations — returning a status of 'valid', 'invalid', 'accept_all', or 'unknown'. Valid emails have over 95% deliverability. Always verify before sending cold outreach to protect your sender reputation.
Does it work with free plans?
Yes. Hunter offers a free plan with 25 email searches and 50 verifications per month. The API key works the same regardless of plan — the only difference is quota limits. Upgrade to a paid plan for higher volumes.
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 Hunter MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
