Frequently asked questions
Can I see my open opportunities through the agent?
Yes! Use the list_close_opportunities tool. The agent will return all deals, and you can ask it to filter for those in an 'Open' or specific pipeline stage.
How do I check the tasks due for today?
Use the list_close_tasks tool. Your agent will fetch the list of CRM tasks, and you can ask it to identify those with a due date of today.
Where do I find my Close API Key?
Log in to Close, go to Settings, and select API Keys. You can generate and copy a new API key from that section.
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 Close MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
