What problem does it solve?

This skill eliminates the tedious, error-prone process of manually setting up Polar payment integration, which requires configuring MCP servers, creating products, setting up webhooks, and writing framework-specific checkout code, saving developers hours of guesswork and documentation searching.

Core Features & Use Cases

• Guided MCP Setup: Step-by-step instructions for installing and authenticating the Polar MCP server across Claude Code, Cursor, and other supported environments.
• End-to-End Polar Configuration: Walks through organization creation, product setup for subscriptions or one-time purchases, and webhook endpoint configuration for both sandbox and production environments.
• Framework-Agnostic Code Generation: Integrates with the polar-integration skill to generate ready-to-use checkout, customer portal, and webhook endpoints for Next.js, Express, FastAPI, and other common backend frameworks.
• Use Case: A developer building a new SaaS app can use this skill to go from zero to a working, testable Polar checkout flow in under 30 minutes without manually piecing together scattered Polar documentation.
