Run this in a terminal to add the server to Claude Code.
What this does
DBHub 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:
DSN DB_TYPE DB_HOST DB_PORT DB_USER DB_PASSWORD DB_NAME TRANSPORT PORT ID SSH_HOST SSH_PORT SSH_USER SSH_PASSWORD SSH_KEY SSH_PASSPHRASE SSH_AUTH_SOCK
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
