Database

Local MCP server that gives an assistant SQL text tools: formatting, plain-English explanation, schema analysis, query building and migration generation.

What you can do

• Format and prettify SQL queries for MySQL, PostgreSQL and SQLite
• Explain a query in plain English, listing tables, columns, conditions and optimization tips
• Parse CREATE TABLE statements into tables, columns, constraints, keys and indexes, and draw an ER diagram in Mermaid
• Build SQL from natural-language descriptions, including filters, aggregation, joins, ordering and pagination
• Compare old and new schemas and generate up and down ALTER TABLE migrations

When to use it

Useful when you work with SQL as text and want help tidying queries, understanding unfamiliar SQL, documenting a schema, drafting queries from a description, or producing migration statements between two schema versions, without connecting to a live database.

Requirements

Runs as a local Node.js process installed from the npm package; the README describes installing dependencies, building, and pointing a desktop client at the built entry file. No database connection, account, API key or environment variable is declared.
