PostgreSQL MCP Server
Let your coding agent run SQL, inspect schemas, and handle routine Postgres DBA tasks without leaving the chat.
Overview
io.github.itunified-io/postgres is a Build-phase MCP server that gives AI coding agents 27 tools to query, schema-manage, and administrate PostgreSQL over a stdio connection.
What is this MCP server?
- 27 MCP tools covering queries, schema, CRUD, DBA, HA, and server management
- stdio transport via npx @itunified.io/mcp-postgres (version 2026.4.10)
- Connect with POSTGRES_CONNECTION_STRING to your live or local database
- Suited for agent-driven migrations, ad-hoc SQL, and operational Postgres checks
- Published from itunified-io/mcp-postgres on GitHub with MCP registry schema
- 27 MCP tools documented for queries, schema, CRUD, DBA, HA, and server management
- Package @itunified.io/mcp-postgres version 2026.4.10-1 with stdio transport
What problem does it solve?
Switching between your agent and psql or a GUI for every schema question and SQL tweak breaks flow when you are shipping solo.
Who is it for?
Indie builders with an existing Postgres database who want the agent to run diagnostics, explore tables, and execute approved SQL during backend work.
Skip if: Teams that forbid agent access to production databases or anyone who only needs a one-off migration script without ongoing agent connectivity.
What do I get? / Deliverables
After you register the server with POSTGRES_CONNECTION_STRING, your agent can inspect and change Postgres in-context while you stay in one workspace.
- Agent-callable query and schema operations against your Postgres database
- CRUD and DBA workflows without leaving the agent session
- Repeatable MCP registration for dev, staging, or local databases
Recommended MCP Servers
Journey fit
Solo builders wire up persistence and debug data issues during implementation, which is the Build phase on the Skillselion journey. PostgreSQL access maps to backend work: schema design, queries, CRUD, and server-side data operations.
How it compares
Direct PostgreSQL MCP integration with 27 DBA tools, not a generic SQL tutorial skill or ORM-only workflow.
Common Questions / FAQ
Who is io.github.itunified-io/postgres for?
Solo and small-team builders using AI coding agents who already run PostgreSQL and want query, schema, CRUD, and DBA actions from the agent instead of separate DB clients.
When should I use io.github.itunified-io/postgres?
Use it during Build when modeling schema and writing backend logic, and in Operate when you need quick agent-assisted checks on indexes, replication, or server health.
How do I add io.github.itunified-io/postgres to my agent?
Add the MCP server entry for @itunified.io/mcp-postgres (npx, stdio), set POSTGRES_CONNECTION_STRING to your database URL, and restart Claude Code, Cursor, or your MCP-compatible client.
