Questions
Frequently asked questions
How do I add a databases & storage MCP server to Claude or Cursor?
Open a server page in this category and copy the client config block. For local servers it is a command plus arguments; for hosted remotes it is a URL. Paste it into your client's MCP settings and restart the client.
Are these databases & storage servers free?
Most are open source and free to run. Some connect to paid services and need an API key from that provider. The server page links to the repository or website where pricing, if any, is documented.
How are servers sorted?
By completeness: servers with a package or remote, a repository, a clear description, and recent updates rank first. It is not a quality score or a security review.
