Frequently asked questions
What is the best MCP server for vector databases?
By GitHub stars, the most adopted vector databases entries on MCP Harbor are graphify (★134,032), ruflo (★78,856) and PageIndex (★39,590). Popularity is a starting point only. Check whether the project is maintained by the vendor, when it was last updated and which permissions it needs, then try it on a test account before giving it real credentials.
How do I add an MCP server for vector databases?
Open a listing below, copy the package name or server URL from its README, and add it to your client: claude mcp add in Claude Code, mcpServers in Cursor or Claude Desktop, servers in VS Code. The install guide has copy-paste config for each one.
How many vector databases MCP servers are there?
MCP Harbor currently lists 294 projects that match vector databases. 180 of them were updated in the last 30 days and 83% of the GitHub projects carry an open-source license. The list is rebuilt every day from the official MCP Registry, GitHub, npm and PyPI, so a new server shows up here on the first daily update after it meets the listing criteria.
MCP servers for other tools
Data last updated . Stars and downloads are refreshed every day from GitHub and npm.
