-### Raw MCP Protocol Objects
-
-The FastMCP client attempts to provide a "friendly" interface to the MCP protocol, but sometimes you may need access to the raw MCP protocol objects. Each of the main client methods that returns data has a corresponding `*_mcp` method that returns the raw MCP protocol objects directly.
-
-```python
-# Standard method - returns just the list of tools
-tools = await client.list_tools()
-# tools -> list[mcp.types.Tool]
-
-# Raw MCP method - returns the full protocol object
-result = await client.list_tools_mcp()
-# result -> mcp.types.ListToolsResult
-tools = result.tools
-```
-
-Available raw MCP methods:
-
-*   **`list_tools_mcp()`**: Returns `mcp.types.ListToolsResult`
-*   **`call_tool_mcp(name, arguments)`**: Returns `mcp.types.CallToolResult`
-*   **`list_resources_mcp()`**: Returns `mcp.types.ListResourcesResult`
-*   **`list_resource_templates_mcp()`**: Returns `mcp.types.ListResourceTemplatesResult`
-*   **`read_resource_mcp(uri)`**: Returns `mcp.types.ReadResourceResult`
-*   **`list_prompts_mcp()`**: Returns `mcp.types.ListPromptsResult`
-*   **`get_prompt_mcp(name, arguments)`**: Returns `mcp.types.GetPromptResult`
-*   **`complete_mcp(ref, argument)`**: Returns `mcp.types.CompleteResult`
-
-These methods are especially useful for debugging or when you need to access metadata or fields that aren't exposed by the simplified methods.

 ### Advanced Features
 
 MCP allows servers to interact with clients in order to provide additional capabilities. The `Client` constructor accepts additional configuration to handle these server requests.

-The client transport often has its own error-handling mechanisms, so you can not always trap errors like those raised by `call_tool` outside of the `async with` block. Instead, you can use `call_tool_mcp()` to get the raw `mcp.types.CallToolResult` object and handle errors yourself by checking its `isError` attribute.
