Quick answers

Is Context7 better than GitLab MCP?

Package installs favor Context7: 4,108,483 monthly installs to 421,764. GitLab MCP still ranks #2 of 183 maintained documentation servers. Data as of 2026-08-25; we haven't hands-on tested either.

Can I use Context7 and GitLab MCP together?

Yes - MCP clients accept multiple servers in one config, so you can enable both documentation servers side by side. If their tools overlap, keep the one whose toolset fits to keep your agent's tool list lean.

What environment variables do their READMEs document?

Context7: no environment variables extracted from the README setup; GitLab MCP: 12 environment variables extracted from the README setup. Extraction does not rule out other authentication or configuration steps; check each project's current documentation.
