Show HN: PostgreSQL MCP Server with 135 tools for various purpose
A new PostgreSQL MCP server built in Rust offers 135 tools for database interaction, including utilities for SQL execution, schema inspection, data migration, query analysis, and AI integration via pgvector.
Background
- MCP (Model Context Protocol) is an open standard created by Anthropic that lets AI assistants like Claude interact with external tools and data sources in a structured way. A "MCP server" exposes capabilities that an AI can use on the fly.
- This project is a PostgreSQL MCP server written in Rust — it gives an AI assistant direct, real-time access to a PostgreSQL database, with 135 different tools covering schema inspection, querying, indexing, migrations, and more.
- PostgreSQL is the world's most advanced open-source relational database. Rust is a systems programming language prized for performance and safety, so this server is likely fast and memory-efficient.
- Why it matters: instead of a human running SQL commands or writing one-off scripts, an AI can now browse schemas, identify slow queries, suggest indexes, run EXPLAIN plans, and even perform migrations. The 135-tool surface makes it unusually comprehensive for a single database MCP server.
