MCP server for querying PostgreSQL databases

VerifiedSTDIODesktop onlyDatabases

Overview

AI-generated overview

Local MCP server that lets an assistant query PostgreSQL databases.

What you can do
  • Query PostgreSQL databases from an assistant session.
  • The server is described only as a way to run queries against PostgreSQL; no individual tools, connection settings or result formats are documented in the supplied material.
When to use it
When you want an assistant to read or explore data in a PostgreSQL database from your own machine, for example to answer questions about tables and records without switching to a separate SQL client.
Requirements
Runs as a local process over stdio, installed from the npm package postgres-connector, so Node.js and npm are needed. Desktop only; no web execution. No environment variables, headers or authentication are declared, so how the database connection is supplied is not documented. Network access to the PostgreSQL server is required.
Before you install
No credentials, environment variables or headers are declared, so it is unclear how database access is configured or where connection details are stored. Querying a database can expose sensitive data to the assistant and its model provider, and any write or delete capability is undocumented; review the package before pointing it at production data.

Installation

In SourceWeft

  1. Open Postgres Connector in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

SourceWeft has not started this package in its sandbox yet, so its tools are not known.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
