Sezzlee PostgreSQL MCP Server

What this does

Sezzlee PostgreSQL exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.

Requirements

This server needs the following environment variables to be set before it can run:

SEZZLEE_POSTGRES_SERVER
SEZZLEE_POSTGRES_PORT
SEZZLEE_POSTGRES_DATABASE
SEZZLEE_POSTGRES_USER
SEZZLEE_POSTGRES_PASSWORD
SEZZLEE_POSTGRES_SSL_MODE
SEZZLEE_POSTGRES_CONNECT_TIMEOUT_MS
SEZZLEE_POSTGRES_QUERY_TIMEOUT_MS

Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).

How do I install Sezzlee PostgreSQL?

Run the Claude Code command in the install section to add Sezzlee PostgreSQL to Claude Code, or copy the ready-made config for your client from the install section on this page. Restart your client afterwards and the tools appear in your next conversation.

Which clients work with Sezzlee PostgreSQL?

This page carries setup and config for Claude Code, Claude Desktop, Cursor and VS Code. Any other MCP client that accepts a standard server config can connect to Sezzlee PostgreSQL as well.

Does Sezzlee PostgreSQL need an API key?
