Perplexity

Direct shipping calculations inside Cline

The `calculate_prices` tool fetches live shipping rates from Correios directly into your VS Code environment. Cline uses this MCP tool to write, test, and verify your e-commerce pricing logic against live carrier data. When you ask Cline to build a shipping calculator component, it writes the React code, calls this tool to get real Brazilian rates, and checks that the UI renders the pricing correctly.

Auto-fill Brazilian addresses via Cline MCP Server

The `consult_cep` tool retrieves complete address names, neighborhoods, and cities from a single Brazilian ZIP code. Cline invokes this tool to test form validation rules in your signup or checkout pages. You can command Cline to verify that your shipping forms correctly parse Brazilian CEPs. The agent runs the tool, grabs the address payload, and writes assertions to match the returned JSON structure.

Live transit time estimation in your editor

The `estimate_delivery_time` tool calculates how long a package takes to travel between two Brazilian postal codes. Cline uses this tool to populate delivery date badges in your product list components. Tell Cline to add a Brazilian delivery badge to your product page. It will write the component, call the estimation tool, and display the accurate delivery window directly in your code.
