Perplexity

Creating New Leads with MCP Server

`create_lead` lets your agent reliably log a new sales lead. Because of the Pydantic validation, you never get unexpected fields—the output is guaranteed to match your required schema. This means zero risk when passing data downstream. You can then list all existing leads using `list_leads`, knowing that every record retrieved adheres strictly to the defined structure.

Managing Customer Data with Pydantic AI

`get_customer_details` pulls a customer's profile, and the response is validated against your models. If the API sends back junk data, the agent fails loud and clear; it doesn't silently corrupt your process. You can also list all customers using `list_customers` with the same guarantee of correctness. Checking group chats requires running `get_group_chat`, making sure every piece of chat metadata is type-safe.

Tracking Internal Staff Records via MCP Server

`list_staff` provides a validated list of all organization employees. The agent uses this clean data set to inform its actions, eliminating guesswork. You can also check specific team metrics using `get_staff_stats`, knowing the output fields are predictable. It's built for correctness. When you need a reliable view of group activity, run `list_group_chats`.
