postgresql-mcp: a read-only PostgreSQL bridge for Claude Code
An MCP server that lets Claude Code inspect schemas, run SELECT queries, and explain plans against your PostgreSQL databases — safely
A surprising amount of debugging boils down to “let me check the database.” Schema lookups, sample row counts, “is this index actually being used,” EXPLAIN plans. None of that is hard to do in psql, but pulling Claude Code into the loop means copy-pasting schemas and query results back and forth, which gets old.
postgresql-mcp is an MCP server that gives Claude Code direct, read-only access to PostgreSQL. Claude does the inspection, you keep the conversation flowing.
