A side-by-side look at the Confirme, by Synapse and Email Verifier MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Confirme, by Synapse for communication work over a hosted endpoint; choose Email Verifier for communication as a local process. You can also run both side by side in one mcpServers block.
