wtinydb-mcp: Model Context Protocol Server for WTinyDB

wtinydb-mcp is an official Model Context Protocol (MCP) server built on top of FastMCP that equips AI agents with tools to architect, validate, scaffold, and generate code for WTinyDB (TinyDB + Pydantic document database engine).

Key Technologies & Libraries

• MCP Protocol: Open standard connecting AI models to external tools and context.

• FastMCP: Python framework for fast MCP server implementation.

• WTinyDB: Pydantic-powered document database engine on top of TinyDB.

• Pydantic v2: Data schema validation and Python AST inspection.

• Pytest: Modern Python testing framework.

• Pytest-Cov: Code coverage measurement for pytest.

• Docker: Containerized test execution environment.

MCP Tools Exposed

1. validate_model_schema(model_code: str): Validates Pydantic document models for WTinyDB compatibility.

2. search_wtinydb_pattern(query: str): Searches the official wisrovi SUITE catalog for WTinyDB architectural patterns.

3. deploy_wtinydb_scaffolding(target_dir: str, project_name: str, scaffold_type: str): Deploys project scaffolding with repository, config, models, and tests.

4. get_wtinydb_architect_blueprints(): Returns code reference and blueprints for WTinyDB features.

5. get_wtinydb_architect_manual(): Returns the comprehensive WTinyDB architecting manual.

6. generate_wtinydb_crud(model_code: str): Automatically generates repository CRUD class for Pydantic models.
