-If you want to try it the remote MCP server and explore it's capabilities, we recommend [Cloudflare's AI Playground](https://playground.ai.cloudflare.com/) for that. Add the `https://mcp.prisma.io/mcp` URL into the text field with the **Enter MCP server URL** placeholder, click **Connect**, and then authenticate with the [Prisma Console](https://console.prisma.io) in the popup window. Once connected, you can send prompts to the Playground and see what MCP tools the LLM chooses based on your prompts.
