MCP Prompt

An MCP prompt is a reusable, parameterized message template exposed by an MCP server that a host application can inject into a conversation to guide the model's behavior for a specific task. Unlike a hardcoded system prompt, MCP prompts are discovered dynamically and can accept arguments that are substituted at render time. They allow server authors to encode best-practice instructions alongside their tools so that any compliant host automatically receives well-crafted guidance.
