io.github.rog0x/schema MCP Server

The MCP server provides schema validation and generation tools for AI agents, enabling JSON Schema and TypeScript type generation, along with robust validation workflows. It supports MCP-related topics and serves as a practical component for model-context workflows.

🛠️ Key Features

JSON Schema generation from sample data (infers types, required fields, formats, enums)
TypeScript interface and type generation from JSON data or schemas
Schema validation with detailed error messages and JSON path tracing

🚀 Use Cases

Build and validate model-context contracts for AI agents
Generate validation schemas to ensure data integrity in MCP pipelines
Produce TypeScript types aligned with JSON schemas for developer tooling

⚡ Developer Benefits

Streamlined schema creation and validation in one server
Clear error reporting to accelerate debugging and integration
Supports multiple MCP-related tools and agent contexts

⚠️ Limitations

Description based on readme excerpt; if further features exist, they are not reflected here
Behavior inferred from typical MCP-schema-tools usage; verify against actual endpoints and API surface

Tools

generate_json_schema

Generate a JSON Schema from sample JSON data. Infers types, required fields, formats (email, date, URI, UUID), and detects enum patterns from multiple examples.

generate_typescript

Generate TypeScript interfaces and types from JSON data or a JSON Schema. Handles nested objects, arrays, optional fields, enums, and union types.

validate_schema

Validate data against a JSON Schema with detailed error messages including JSON path, expected type, actual value, and the violated constraint keyword.

mock_from_schema

Generate realistic mock data from a JSON Schema. Smart field-name detection produces contextual values: email fields get valid emails, name fields get realistic names, phone fields get formatted numbers, etc.

diff_schemas

Compare two JSON Schemas to find added, removed, and changed fields. Identifies type changes, constraint changes, and classifies each difference as breaking or non-breaking for backwards compatibility analysis.
