Tool Tokens
design_schema ~101

Design a database schema from a natural language description. Generates CREATE TABLE SQL (PostgreSQL), index recommendations, and a text-based ERD. Optionally accepts explicit table definitions to validate and enhance.

NameTypeReqDescription
descriptionstringyesNatural language description of the data model (e.g. 'an e-commerce platform with products, orders, and user reviews')
tablesarrayOptional: provide explicit table definitions to validate and enhance instead of generating from description

No output schema declared.

No examples provided.

generate_types ~89

Generate typed code from SQL CREATE TABLE statements. Supports three output formats: TypeScript interfaces, Zod validation schemas, or JSON Schema definitions.

NameTypeReqDescription
formatstringyesOutput format: 'typescript' for interfaces, 'zod' for Zod schemas, 'json-schema' for JSON Schema
sqlstringyesSQL CREATE TABLE statements (PostgreSQL dialect) to generate types from

No output schema declared.

No examples provided.

migrate_schema ~83

Generate migration SQL by diffing a "from" schema against a "to" schema. Produces ALTER TABLE statements in safe dependency order, rollback SQL, and warnings for destructive changes (column drops, type changes).

NameTypeReqDescription
from_sqlstringyesCurrent database schema as SQL CREATE TABLE statements
to_sqlstringyesTarget database schema as SQL CREATE TABLE statements

No output schema declared.

No examples provided.

optimize_queries ~76

Analyze a SQL query against a schema and suggest performance improvements. Identifies missing indexes, recommends query rewrites, and provides EXPLAIN plan interpretation hints.

NameTypeReqDescription
querystringyesThe SQL query to optimize
schemastringyesSchema context as SQL CREATE TABLE statements, so the tool can identify missing indexes and table structure

No output schema declared.

No examples provided.

validate_schema ~81

Validate SQL CREATE TABLE statements for best practices. Checks for missing primary keys, unnamed constraints, missing FK indexes, data type issues (e.g. TIMESTAMP vs TIMESTAMPTZ), naming conventions (snake_case, plural tables), and N+1 query risks.

NameTypeReqDescription
