IaC Memory MCP Server: Persistent Storage and Intelligent Resource Management for AI Applications

Overview: What is IaC Memory MCP Server?

The IaC Memory MCP (Model Context Protocol) Server is an advanced solution designed to enhance Claude AI's capabilities by providing persistent memory storage for Infrastructure-as-Code (IaC) components. This server focuses on version tracking, relationship mapping, and comprehensive documentation management for Terraform and Ansible resources. By leveraging the Model Context Protocol (MCP), it ensures that IaC component data is accessible, consistent, and version-aware, enabling seamless integration with various AI applications such as Claude Desktop, Continue, Cursor, and others.

🔧 Core Features & MCP Capabilities

Resource Management

The server implements sophisticated resource management capable of organizing resources hierarchically via URI-based access. Resources are structured in a clear and logical manner under the following URI patterns:

resources://<platform>/<category>/<name>

Supported Platforms:

• Terraform: For AWS, Google Cloud, Azure configurations.
• Ansible: For Playbooks, Collections, Modules.
• iac (General Infrastructure Entities): For custom or generic resources.

Example URIs include:

resources://terraform/providers/aws
resources://terraform/resources/aws/s3_bucket

Dynamic Resource Templates

Resource templates are dynamically generated for easy access and utilization. These templates provide standardized data access patterns, making it easier to retrieve information about providers, resource types, collections, modules, etc.

Prompts & Analytical Tools

The server supports four advanced prompts:

1. search_resources

   • Purpose: Search for IaC resources.
   • Arguments:
     • provider: Provider name (e.g., aws).
     • resource_type: Type of resource (e.g., s3_bucket).

2. analyze_entity

   • Purpose: Analyze an entity and its relationships.
   • Arguments:
     • entity_id: Unique identifier for the entity.
     • include_relationships: Boolean value to determine if related entities are included.

3. terraform_provider

   • Purpose: Get information about a Terraform provider.
   • Arguments:
     • provider_name: Name of the provider (e.g., aws).
     • version: Optional specific version inquiry.

4. ansible_module

   • Purpose: Get information about an Ansible module.
   • Arguments:
     • collection_name: Name of the Ansible collection.
     • module_name: Specific module name.
     • version: Optional specific version inquiry.

Tools for IaC Component Management

The server includes comprehensive tools for managing Terraform and Ansible components, including:

• Terraform:

  • get_terraform_provider_info
  • list_provider_resources
  • get_terraform_resource_info
  • add_terraform_provider
  • add_terraform_resource
  • update_provider_version

• Ansible:

  • get_ansible_collection_info
  • list_ansible_collections
  • get_collection_version_history
  • get_ansible_module_info
  • list_collection_modules
  • get_module_version_compatibility

Additionally, it supports entity operations for creating, updating, and deleting entities.

⚙️ MCP Architecture & Protocol Implementation

The IaC Memory MCP Server follows the Model Context Protocol (MCP) architecture designed to facilitate seamless communication between AI applications, data sources, and tooling. The protocol ensures efficient and secure interaction by providing:

1. Persistent Storage: A robust storage mechanism for IaC component data.
2. Version Tracking: Comprehensive version tracking of individual resources and entities.
3. Relationship Mapping: Advanced relationship mapping to understand dependencies between components.
4. Schema Validation & Metadata: Real-time schema validation and metadata recording for enhanced security.

🚀 Getting Started with Installation

Configuration Environment Variables

For development, you can configure the server using environment variables:

DATABASE_URL=sqlite:////path/to/db.sqlite
MCP_DEBUG=1
MCP_TEST_MODE=1

Create a .env file to store these values.

Development Setup

To integrate with Claude Desktop, include the following in your development setup JSON configuration:

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

For production setups, use:

"mcpServers": {
  "iac-memory": {
    "command": "uvx",
    "args": [
        "--from",
        "git+https://github.com/AgentWong/iac-memory-mcp-server.git",
        "python",
        "-m",
        "iac_memory_mcp_server"
    ],
    "env": {
          "DATABASE_URL": "sqlite:////home/herman/iac.db"
      }
  }
}
