Dynamic Arguments

Parametrizing Context

Prompts achieve their power through arguments. Just like tools, you can use Zod to define what inputs a prompt requires.

server.prompt(
  "generate_report",
  { 
    department: z.string().describe("e.g. Sales, Marketing"),
    quarter: z.string().describe("e.g. Q1-2026")
  },
  ({ department, quarter }) => ({
    // Build context tailored to the department and quarter...
  })
);

When the user selects "Generate Report" in Claude Desktop, the UI will prompt them to type in the Department and Quarter before creating the message block.

How do you enforce strongly-typed arguments for a Prompt?
By using Zod schema definitions.

It is not possible; Prompts only take raw text.
