## Prompts
|
|
|
|
**Server-side**:
|
|
MCP servers can provide LLM prompt templates (called simply _prompts_) to clients.
|
|
Every prompt has a required name which identifies it, and a set of named arguments, which are strings.
|
|
Construct a prompt with a name and descriptions of its arguments.
|
|
Associated with each prompt is a handler that expands the template given values for its arguments.
|
|
Use [`Server.AddPrompt`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp#Server.AddPrompt)
|
|
to add a prompt along with its handler.
|
|
If `AddPrompt` is called before a server is connected, the server will have the `prompts` capability.
|
|
If all prompts are to be added after connection, set [`ServerOptions.HasPrompts`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp#ServerOptions.HasPrompts)
|
|
to advertise the capability.
|
|
|
|
**Client-side**:
|
|
To list the server's prompts, call
|
|
Call [`ClientSession.Prompts`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp#ClientSession.Prompts) to get an iterator.
|
|
If needed, you can use the lower-level
|
|
[`ClientSession.ListPrompts`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp#ClientSession.ListPrompts) to list the server's prompts.
|
|
Call [`ClientSession.GetPrompt`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp#ClientSession.GetPrompt) to retrieve a prompt by name, providing
|
|
arguments for expansion.
|
|
Set [`ClientOptions.PromptListChangedHandler`](https://pkg.go.dev/github.com/modelcontextprotocol/go-sdk/mcp#ClientOptions.PromptListChangedHandler) to be notified of changes in the list of prompts.
