IaC Memory MCP Server

IaC Memory MCP Server

A Model Context Protocol (MCP) server that enhances Claude AI's capabilities by providing persistent memory storage for Infrastructure-as-Code (IaC) components, with a focus on version tracking and relationship mapping for Terraform and Ansible resources.

[!NOTE] This was a personal project to determine the state of AI's ability if the person using it (me)doesn't have subject matter expertise (lack of Python knowledge). Since it has become rather costprohibitive, I do not intend to develop or maintain this project further.

Overview

The IaC Memory MCP Server addresses the challenge of maintaining accurate, version-aware context for IaC components by providing:

• Persistent storage and version tracking for IaC components
• Hierarchical resource organization with URI-based access
• Comprehensive relationship mapping between components
• Version-specific documentation management
• Schema validation and temporal metadata tracking
• Automated relationship analysis and insights

Core Components

Resource Management

The server implements a sophisticated resource management system with hierarchical URIs:

Resource URI Structure

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

Supported platforms:

• terraform
• ansible
• iac (for general infrastructure entities)

Example URIs:

resources://terraform/providers/aws
resources://terraform/resources/aws/s3_bucket
resources://ansible/collections/community.aws
resources://ansible/modules/community.aws/s3_bucket

Resource Templates

The server provides dynamic resource templates for standardized access patterns:

• Terraform provider information: resources://terraform/providers/{provider_name}
• Resource type details: resources://terraform/resources/{provider_name}/{resource_type}
• Ansible collection data: resources://ansible/collections/{collection_name}
• Module information: resources://ansible/modules/{collection_name}/{module_name}

Prompts

The server implements four specialized prompts for IaC component discovery and analysis:

search_resources

• Purpose: Search for IaC resources
• Arguments:
  • provider: Provider name
  • resource_type: Resource type
• Returns: Information about specific resources for the given provider

analyze_entity

• Purpose: Analyze an entity and its relationships
• Arguments:
  • entity_id: Entity ID
  • include_relationships: Include relationships
• Returns: Detailed entity analysis including name, type, and observations

terraform_provider

• Purpose: Get information about a Terraform provider
• Arguments:
  • provider_name: Name of the Terraform provider (required)
  • version: Specific version to query (optional)
• Returns: Detailed provider information for the specified version

ansible_module

• Purpose: Get information about an Ansible module
• Arguments:
  • collection_name: Name of the Ansible collection (required)
  • module_name: Name of the module (required)
  • version: Specific version to query (optional)
• Returns: Detailed module information for the specified version

Tools

The server implements comprehensive tooling for IaC component management:

Terraform Tools

• get_terraform_provider_info: Retrieve detailed provider information including version and resources
• list_provider_resources: List all resources available for a specific provider
• get_terraform_resource_info: Get detailed information about a specific resource type
• add_terraform_provider: Register new providers with versioning
• add_terraform_resource: Add resource definitions with schemas
• update_provider_version: Update provider versions with new documentation

Ansible Tools

• get_ansible_collection_info: Get detailed information about an Ansible collection
• list_ansible_collections: List all available Ansible collections
• get_collection_version_history: View version history of a collection
• get_ansible_module_info: Get detailed information about a specific module
• list_collection_modules: List all modules in a collection
• get_module_version_compatibility: Check version compatibility of modules
• add_ansible_collection: Register new Ansible collections
• add_ansible_module: Add new modules with validation and documentation

Entity Operations

• create_entity: Create new infrastructure entities
• update_entity: Modify existing entity configurations
• delete_entity: Remove entities with relationship cleanup
• view_relationships: Analyze entity dependencies and relationships

Configuration

The server supports configuration through environment variables:

• DATABASE_URL: SQLite database location
• MCP_DEBUG: Enable debug logging when set
• MCP_TEST_MODE: Enable test mode for database resets

For development, create a .env file:

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