MySQL & PostgreSQL MCP Server

MCPOpen SourceMIT25.4

by kaulvimal • Visualization & Charts

A read-only MCP server that lets MCP-compatible clients inspect schemas, metadata, and run read-only SQL queries against MySQL and PostgreSQL databases.

Example Use Cases

1
Inspect and document the schema of a MySQL or PostgreSQL database without direct write access.
2
Run read-only SQL queries, get execution plans (EXPLAIN), and fetch metadata for automated analysis or reporting.
3
Generate visual schema representations (JSON, DOT, Mermaid) or discover relationships and navigation paths between tables.

Description

This project implements a Model Context Protocol (MCP) server exposing tools to explore database schemas, retrieve metadata (tables, columns, indexes, constraints), discover relationships, and execute read-only queries (SELECT, EXPLAIN, DESCRIBE). It includes schema visualization outputs (JSON, DOT, Mermaid) and utilities for comparing schemas and finding navigation paths between tables. The server is built for safety (read-only operations) and extensibility, and is intended to be run locally or integrated with MCP-capable clients.
