`fastmcp.server.transforms.prompts_as_tools`

Transform that exposes prompts as tools. This transform generates tools for listing and getting prompts, enabling clients that only support tools to access prompt functionality. The generated tools route through ctx.fastmcp at runtime, so all server middleware (auth, visibility, rate limiting, etc.) applies to prompt operations exactly as it would for direct prompts/get calls. Example:

from fastmcp import FastMCP
from fastmcp.server.transforms import PromptsAsTools

mcp = FastMCP("Server")
mcp.add_transform(PromptsAsTools(mcp))
# Now has list_prompts and get_prompt tools

Classes

`PromptsAsTools`

Transform that adds tools for listing and getting prompts. Generates two tools:

list_prompts: Lists all prompts
get_prompt: Gets a specific prompt with optional arguments

The generated tools route through the server at runtime, so auth, middleware, and visibility apply automatically. This transform should be applied to a FastMCP server instance, not a raw Provider, because the generated tools need the server’s middleware chain for auth and visibility filtering. Methods:

`list_tools`

list_tools(self, tools: Sequence[Tool]) -> Sequence[Tool]

Add prompt tools to the tool list.

`get_tool`

get_tool(self, name: str, call_next: GetToolNext) -> Tool | None

Get a tool by name, including generated prompt tools.
