How is this list ranked?

Our picks follow real search demand for each app's MCP server, then we choose the best live server for that app (official first). The second list ranks every other live server by trust score: uptime, verified publisher, maintenance, adoption and transparency.

Can I pay to be on this list?

No. Rankings and grades can't be bought. Sponsored slots are always labeled Featured and sit outside the ranking.

Why are some popular servers missing?

This list only includes remote servers that use OAuth or no sign-in, because that's all ChatGPT and claude.ai can connect to. Local servers work in Claude Desktop, Claude Code, Cursor and VS Code.
