The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | Natural language description of the data model (e.g. 'an e-commerce platform with products, orders, and user reviews') |
| tables | array | – | Optional: 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.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | yes | Output format: 'typescript' for interfaces, 'zod' for Zod schemas, 'json-schema' for JSON Schema |
| sql | string | yes | SQL 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).
| Name | Type | Req | Description |
|---|---|---|---|
| from_sql | string | yes | Current database schema as SQL CREATE TABLE statements |
| to_sql | string | yes | Target 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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | The SQL query to optimize |
| schema | string | yes | Schema 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.
| Name | Type | Req | Description |
|---|---|---|---|
| sql | string | yes | SQL CREATE TABLE statements (PostgreSQL dialect) to validate |
No output schema declared.
No examples provided.
