User Info MCP Server

A simple MCP (Model Context Protocol) server that provides user information management through tool calls. Built with FastMCP for efficient context sharing.

Features

  • Dynamic Mode: Allows session-based user info storage when USER_MANAGED=true

  • Multiple Transports: Supports both stdio and HTTP communication

  • Date Integration: Automatically includes current date in responses

Usage Examples

Getting User Info

# The tool automatically includes current date user_info = await get_user_info() # Returns: "=== CURRENT DATE: 2024-01-15 ===\nUSE THIS DATE FOR ALL CALCULATIONS\n\n[your user info]"

Storing User Info (Dynamic Mode)

await put_user_info(""" Name: John Doe Company: Tech Corp Location: San Francisco, CA Role: Software Engineer Interests: - Python development - Machine learning - Open source """)

Dependencies

  • fastmcp>=2.11.3 - MCP server framework

  • uv - Python package manager (for running)

Notes

  • In dynamic mode, user information is stored in memory and persists only for the current session

  • The current date is automatically included in all responses and should be trusted for calculations

  • Static mode falls back to a default message if user_info.txt doesn't exist
