MCP prompt

Definition

An MCP prompt is a reusable, parameterized message template an MCP server offers, which a user can invoke to start a task with the model.

Prompts are the least-used of MCP's three primitives (tools, resources, prompts). They let a server ship ready-made workflows — e.g. 'summarize this PR' — that surface in the client as slash-command-like options. Useful, but most servers skip them and ship tools only.
