Frequently asked questions
Can I see if a client has opened my proposal using the agent?
Yes! Use the get_proposal tool with the Proposal ID. Your agent will fetch the latest status, which includes whether the proposal has been viewed, signed, or paid.
How do I list all my saved proposal templates?
Simply ask the agent to list_templates. It will retrieve all the proposal templates available in your account for you to review and use.
Does the integration allow me to create a new contact?
Yes! Use the create_contact action with the name and email. Your agent will register the new contact in your Better Proposals CRM instantly.
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 Better Proposals MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
