Mcp Postgres Nl Query

Lets an assistant inspect a PostgreSQL schema and run read-only or natural-language queries with tenant and row-level-security awareness.

What you can do

This local MCP server connects an assistant to a PostgreSQL database. It exposes the schema for inspection, executes read-only SQL, and translates natural-language questions into SQL while applying safety rails. It is described as row-level-security and tenant aware, so queries are scoped to the appropriate tenant context.

When to use it

Use it when an assistant needs to explore or query a PostgreSQL database in natural language without granting write access. It suits multi-tenant setups where row-level security must be respected during agent-driven queries.

Requirements

Runs as a local process on the user's machine via the npm package @infoinlet/mcp-postgres-nl-query over stdio. Desktop only; no web execution. No authentication, environment variables, or headers are declared, so database connection details must be supplied by other means.
