IaC Memory MCP Server

This is a personal project to see if Claude 3.5 Sonnet can write a moderately complex MCP Server in Python.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "agentwong-iac-memory-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/iac-memory-mcp-server",
        "run",
        "iac-memory-mcp-server"
      ],
      "env": {
        "DATABASE_URL": "sqlite:////home/herman/iac.db"
      }
    }
  }
}

IaC Memory MCP Server provides persistent memory storage with version-aware context for Infrastructure-as-Code components. It organizes IaC resources, tracks relationships, and enables quick discovery and analysis of Terraform and Ansible artifacts, helping you maintain accurate, up-to-date context for your infrastructure definitions.

How to use

You integrate the IaC Memory MCP Server with your MCP client to explore, analyze, and manage IaC components. Use the search features to discover resources, analyze entities to understand dependencies, and retrieve provider or module details for Terraform and Ansible. The server exposes hierarchical resource URIs, supports relationship mappings, and returns version-aware information to help you reason about changes over time.
