Classes

​
ClientPromptsMixin

Mixin providing prompt-related methods for Client. Methods:

​
list_prompts_mcp 

list_prompts_mcp(self: Client) -> mcp.types.ListPromptsResult
Send a prompts/list request and return the complete MCP protocol result. Args:
  • cursor: Optional pagination cursor from a previous request’s nextCursor.
Returns:
  • mcp.types.ListPromptsResult: The complete response object from the protocol, containing the list of prompts and any additional metadata.
Raises:
  • RuntimeError: If called while the client is not connected.
  • McpError: If the request results in a TimeoutError | JSONRPCError

​
list_prompts 

list_prompts(self: Client) -> list[mcp.types.Prompt]
Retrieve all prompts available on the server. This method automatically fetches all pages if the server paginates results, returning the complete list. For manual pagination control (e.g., to handle large result sets incrementally), use list_prompts_mcp() with the cursor parameter. Returns:
  • list[mcp.types.Prompt]: A list of all Prompt objects.
Raises:
  • RuntimeError: If called while the client is not connected.
  • McpError: If the request results in a TimeoutError | JSONRPCError

​
get_prompt_mcp 

get_prompt_mcp(self: Client, name: str, arguments: dict[str, Any] | None = None, meta: dict[str, Any] | None = None) -> mcp.types.GetPromptResult
Send a prompts/get request and return the complete MCP protocol result. Args:
  • name: The name of the prompt to retrieve.
  • arguments: Arguments to pass to the prompt. Defaults to None.
  • meta: Request metadata (e.g., for SEP-1686 tasks). Defaults to None.
Returns:
  • mcp.types.GetPromptResult: The complete response object from the protocol, containing the prompt messages and any additional metadata.
Raises:
  • RuntimeError: If called while the client is not connected.
  • McpError: If the request results in a TimeoutError | JSONRPCError

​
get_prompt 

get_prompt(self: Client, name: str, arguments: dict[str, Any] | None = None) -> mcp.types.GetPromptResult

​
get_prompt 

get_prompt(self: Client, name: str, arguments: dict[str, Any] | None = None) -> PromptTask

​
get_prompt 

get_prompt(self: Client, name: str, arguments: dict[str, Any] | None = None) -> mcp.types.GetPromptResult | PromptTask
Retrieve a rendered prompt message list from the server. Args:
  • name: The name of the prompt to retrieve.
  • arguments: Arguments to pass to the prompt. Defaults to None.
  • version: Specific prompt version to get. If None, gets highest version.
  • meta: Optional request-level metadata.
  • task: If True, execute as background task (SEP-1686). Defaults to False.
  • task_id: Optional client-provided task ID (auto-generated if not provided).
  • ttl: Time to keep results available in milliseconds (default 60s).
Returns:
  • mcp.types.GetPromptResult | PromptTask: The complete response object if task=False, or a PromptTask object if task=True.
Raises:
  • RuntimeError: If called while the client is not connected.
  • McpError: If the request results in a TimeoutError | JSONRPCError
