Adding instructions to the server

[IDmedia]

I use fastapi_mcp with PydanticAI and it works great for tools, but is there a way to tell the AI the correlation between functions and give it a worflow/instructions to follow when using this MCP server?

Looking at FastMCP and its documentation it has this:

from fastmcp import FastMCP

# Create a basic server instance
mcp = FastMCP(name="MyAssistantServer")

# You can also add instructions for how to interact with the server
mcp_with_instructions = FastMCP(
    name="HelpfulAssistant",
    instructions="This server provides data analysis tools. Call get_average() to analyze numerical data."
)

I prefer this library for it's simplicity. Is there an alternative that would allow me to pass instructions to the AI through the MCP?
