NEW MCP Prompt Completions

MCP Prompt Completions

A prompt field that merely accepts text is functional - but a prompt field that guides the user with intelligent suggestions creates a dramatically better experience. MCP prompt completions make prompts feel less like raw API inputs and more like polished, interactive UI components.

NEW Defining MCP Prompts

Defining MCP Prompts

Most users shouldn't have to become prompt engineers just to get great results from AI. MCP prompts let you encapsulate sophisticated prompt engineering into reusable, standardized capabilities that deliver consistent, high-quality LLM interactions across every client that uses them.
