# Hints and MCP Servers > Source: > Published: 2026-08-05 07:00:00+00:00 I am making some sort of **customer service MCP server** for my own use. I can tell an LLM (such as `LFM2.5-2.6B-Q4_K_M.gguf` in `llama-cpp` ) what I want, and it will do it for me. I have been thinking for ways for an AI agent to convey to the MCP server what the user is talking about. Basically, if the user says something like "view tutorial XYZ", the AI agent needs to provide a `hint` about what the person is asking about. The `view_file` tool has an optional `hint` parameter, and the tool description says to use `hint` "t" when the user is talking about tutorials. Then in the **Rust MCP server**, the code can use the `hint` (alongside the `name` ) and use it to help find the appropriate page. So if the user is talking about **tutorials**, it will return a page that more closely matches tutorials rather than blog posts. The goal of the LLM is to parse in **natural language** and provide my own functions (like `view_file` ) with information about what the user was talking about. The `hint` can give **better results** than just a `name` ; having the LLM help determine the context of the request is useful.
