Frequently asked questions
How do I find my Buddy Punch Subscription Key?
Log in to the Buddy Punch Developer Hub, navigate to your profile, and copy your Subscription Key (requires an active Enterprise plan).
Can I punch in an employee via AI?
Yes! The punch_in_out tool allows your agent to record a punch action by providing the employee ID and punch type (In/Out) programmatically.
How do I retrieve time entries for payroll?
Use the list_time_entries tool to retrieve detailed historical records of all work duration and breaks for the current pay period.
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 Buddy Punch MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
