Amazon DynamoDB MCP Server

Generates type-safe Python code from schema.json including entity classes with field validation, repository classes with CRUD operations, fully implemented access patterns, and optional usage examples. The generated code uses Pydantic for validation and boto3 for DynamoDB operations.

Java JRE version 17 or newer (set `JAVA_HOME` or ensure `java` is in your system PATH)

Validates your DynamoDB data model by loading dynamodb_data_model.json, setting up DynamoDB Local, creating tables with test data, and executing all defined access patterns. Saves detailed validation results to dynamodb_model_validation.json.

Analyzes existing MySQL databases to extract schema structure, access patterns from Performance Schema, and generates timestamped analysis files for use with dynamodb_data_modeling. Supports both RDS Data API-based access and connection-based access.

Converts your data model (dynamodb_data_model.md) into a structured schema.json file representing your DynamoDB tables, indexes, entities, fields, and access patterns. This machine-readable format is used for code generation and can be extended for other purposes like documentation generation or infrastructure provisioning. Automatically validates the schema with up to 8 iterations to ensure corre

Validates schema.json files for code generation compatibility. Checks field types, operations, GSI mappings, pattern IDs, and provides detailed error messages with fix suggestions. Ensures your schema is ready for the generate_data_access_layer tool.
