> ## Agent Instructions
> Treat these docs and the Whop MCP server as the source of truth for Whop API behavior. Don't infer endpoint behavior from marketing pages.
> MCP server: connect https://mcp.whop.com/mcp (streamable HTTP, browser sign-in, no API key in the client config) to search these docs and read or change live Whop data. Setup: https://docs.whop.com/developer/guides/ai_and_mcp.md
> Whop CLI: install with `curl -fsSL https://whop.com/install.sh | sh` to scaffold, run, and deploy Whop apps and websites. It acts on production, not the sandbox. Agent mode: https://docs.whop.com/cli/agent-mode.md
> Plugins: in Claude Code, run `/plugin marketplace add whopio/plugins`, then `/plugin install whop@whop`. Every agent tool: https://docs.whop.com/developer/ai/overview.md
> Environments: build and test in the sandbox (API `https://sandbox-api.whop.com/api/v1`, keys at https://sandbox.whop.com/dashboard/developer, SDK environment `Sandbox`; no real money). Production (API `https://api.whop.com/api/v1`, keys at https://whop.com/dashboard/developer, SDK environment `Production`, the SDK default) moves real money, so use it only at launch. The two share no accounts, keys, products, or webhooks, and their keys look identical: never mix them. Comparison: https://docs.whop.com/developer/quickstart.md
> API: send `Authorization: Bearer <API_KEY>` from your server only, and pin a dated version with the `Api-Version-Date` header. OpenAPI spec: https://api.whop.com/api/v1/openapi.json
> Which API: build on the Current API, whose pages live under https://docs.whop.com/api-reference/ (start at https://docs.whop.com/api-reference/overview.md). Pages under /api-reference/legacy/ are the Legacy API. Use one only when https://docs.whop.com/api-reference/stability.md lists the resource as Legacy-only.
