Local Utilities MCP Server

A Python-based MCP server offering text, file, time, and security utilities via HTTP/stdio transport.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "aiforhumans-local-utils-mcp": {
      "command": "python",
      "args": [
        "server.py"
      ]
    }
  }
}

You run a local MCP server that exposes practical utilities for text, files, time, and security tasks. Built with FastMCP, it lets you perform common operations from a unified interface, making it easy to automate and integrate into your tools and workflows.

How to use

You connect to the server using an MCP client that supports stdio transports. Start by launching the server locally and then issue tool requests from your client. The server provides a suite of utilities such as temperature conversion, file operations, hashing, text analysis, date and time information, and password generation. Each tool returns structured results you can use in scripts, dashboards, or subsequent MCP actions.
