FAQ

DBHub FAQ

Still curious? Email info@appsgit.com.

How do I install the DBHub MCP server?

Add the command npx -y @bytebase/dbhub to your MCP client: put it in claude_desktop_config.json for Claude Desktop, run claude mcp add for Claude Code, or add it to .cursor/mcp.json (Cursor) or .vscode/mcp.json (VS Code). The snippets on this page are ready to paste.

Is DBHub free?

The server is open source under the MIT license, so running it is free. It needs credentials (DSN, DB_PASSWORD, SSH_PASSWORD, SSH_PASSPHRASE and SSH_AUTH_SOCK) for the service it connects to, which may require a paid account.

Is DBHub actively maintained?

The most recent commit was on Oct 21, 2026. The latest release is v1.5.0, published Oct 9, 2026. appsgit only lists MCP servers with a commit in the last six months.
