# `fastmcp.prompts.prompt`
Base classes for FastMCP prompts.
## Functions
### `Message`
```python
Message(content: str | ContentBlock, role: Role | None = None, **kwargs: Any) -> PromptMessage
```
A user-friendly constructor for PromptMessage.
## Classes
### `PromptArgument`
An argument that can be passed to a prompt.
### `Prompt`
A prompt template that can be rendered with parameters.
**Methods:**
#### `enable`
```python
enable(self) -> None
```
#### `disable`
```python
disable(self) -> None
```
#### `to_mcp_prompt`
```python
to_mcp_prompt(self, **overrides: Any) -> MCPPrompt
```
Convert the prompt to an MCP prompt.
#### `from_function`
```python
from_function(fn: Callable[..., PromptResult | Awaitable[PromptResult]], name: str | None = None, title: str | None = None, description: str | None = None, icons: list[Icon] | None = None, tags: set[str] | None = None, enabled: bool | None = None, meta: dict[str, Any] | None = None) -> FunctionPrompt
```
Create a Prompt from a function.
The function can return:
- A string (converted to a message)
- A Message object
- A dict (converted to a message)
- A sequence of any of the above
#### `render`
```python
render(self, arguments: dict[str, Any] | None = None) -> list[PromptMessage]
```
Render the prompt with arguments.
This method is not implemented in the base Prompt class and must be
implemented by subclasses.
### `FunctionPrompt`
A prompt that is a function.
**Methods:**
#### `from_function`
```python
from_function(cls, fn: Callable[..., PromptResult | Awaitable[PromptResult]], name: str | None = None, title: str | None = None, description: str | None = None, icons: list[Icon] | None = None, tags: set[str] | None = None, enabled: bool | None = None, meta: dict[str, Any] | None = None) -> FunctionPrompt
```
Create a Prompt from a function.
The function can return:
- A string (converted to a message)
- A Message object
- A dict (converted to a message)
- A sequence of any of the above
#### `render`
```python
render(self, arguments: dict[str, Any] | None = None) -> list[PromptMessage]
```
