Postgres Connector
Connect your agent to a live PostgreSQL database so it can run read queries and inspect schema while you implement features or fix data bugs.
Overview
io.github.martymarkenson/postgres-connector is a MCP server for the Build phase that lets AI agents query PostgreSQL databases over stdio.
What is this MCP server?
- MCP bridge for PostgreSQL query execution from the agent
- stdio npm package postgres-connector v1.0.2
- Fits local dev, staging, or tunnelled production read replicas when you configure connection strings safely
- Lightweight connector focused on querying rather than full ORM management
- Package version 1.0.2 on npm identifier postgres-connector
- Transport: stdio
- Scope: querying PostgreSQL databases (per registry description)
What problem does it solve?
Builders constantly copy SQL into psql or GUI tools while the agent guesses at table names and joins without seeing real data.
Who is it for?
Solo SaaS builders with a Postgres-backed app who want the agent to explore data safely during backend development.
Skip if: Teams that need governed BI semantics, row-level audit on every tool call, or databases other than PostgreSQL without another connector.
What do I get? / Deliverables
The agent can run authorized queries against your Postgres instance so answers reflect actual schema and sample rows in the same coding session.
- Query results and schema-aware answers grounded in live PostgreSQL data
- Faster iteration on SQL and API handlers without leaving the agent thread
Recommended MCP Servers
Journey fit
SQL access against your app's database belongs in Build when backend logic, migrations, and data shapes are actively changing. Backend is the canonical shelf because the primary job is querying and understanding relational data behind your API, not marketing analytics dashboards.
How it compares
Thin SQL query MCP for Postgres, not a full data pipeline, warehouse sync, or ORM code generator.
Common Questions / FAQ
Who is io.github.martymarkenson/postgres-connector for?
Indie developers and small teams building on PostgreSQL who want their coding agent to inspect and query the database during implementation and debugging.
When should I use io.github.martymarkenson/postgres-connector?
Use it in Build/backend work when you need to verify queries, understand relationships, or debug data issues while pairing with your agent on API or SQL changes.
How do I add io.github.martymarkenson/postgres-connector to my agent?
Install the npm stdio package postgres-connector v1.0.2, add it to your MCP server list, and configure your PostgreSQL connection string and network access per your agent's secrets handling.
