Run this in a terminal to add the server to Claude Code.
What this does
pgops 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:
PGOPS_DSN PGOPS_READONLY_DSN PGOPS_READ_ONLY PGOPS_APPROVAL_MODE PGOPS_AUDIT_LOG PGOPS_DEFAULT_TIMEOUT_MS PGOPS_MAX_TIMEOUT_MS PGOPS_DEFAULT_ROW_LIMIT
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
