Agent Index vs Fetch
A side-by-side look at the Agent Index and Fetch MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Agent Index for search & data extraction work as a local process; choose Fetch for search & data extraction as a local process. You can also run both side by side in one mcpServers block.
