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.

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
