Helisis MCP

Open this server in Claude and paste one URL.

Anthropic’s current custom connector flow is still manual: open Claude’s Connectors settings, choose Add custom connector, and paste the MCP server URL below. This server exposes authenticated PostgreSQL tools plus read_only_sql, with the raw SQL path running directly in the Next.js server and the typed PostgreSQL tool catalog still routed through Convex where that hop remains the cleaner boundary today.

Why this page exists

Anthropic’s official remote MCP docs currently describe a manual connector-add flow via Claude settings rather than a one-click install URL. This page shortens that path by giving operators the exact settings page and the exact server URL in one place while staying honest about the current runtime split.
