Schema Tools Reference
Complete reference for the 13 MCP tools and 3 resources available in the NeoArc Studio Schema MCP server, covering schema CRUD, model generation, drift detection, lineage, and breaking change analysis.
Schema MCP Server
The schema server provides full access to API schema definitions (.schema.json). Schemas define the data contracts for REST APIs, GraphQL operations, gRPC methods, webhooks, and MCP tools. The server's most powerful capability is its integration with the central data model - schemas can be auto-generated with full lineage tracking, and drift detection identifies when they diverge from their source.
Discovery Tools
Explore and inspect existing schemas in the workspace.
Schema CRUD
Create schemas and manage their fields. Each field has a type, optional specialisation (e.g. email, uuid, int32), validation rules using an expression tree, and optional lineage linking it to a model entity property.
Model Integration
The most powerful tools in the schema server. Generate schemas directly from data model entities with automatic lineage tracking, then use drift detection to keep them aligned over time.
Analysis and Governance
Validate schemas, check for breaking changes before modifying fields, trace lineage coverage, and find every place a schema is referenced across your API ecosystem.
Inheritance
Schemas support inheritance via the extends field. A schema can inherit fields from one or more parent schemas, with optional lineage overrides for inherited fields.
Resources
Reference data the AI can read on demand to understand field types, validation rules, and schema structure.
