Zyntra - Temp e-mails MCP — questions

Answers built from our own checks of this server.

Why is there no tool list for Zyntra - Temp e-mails MCP?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.

Is Zyntra - Temp e-mails MCP working right now?

How do I connect Zyntra - Temp e-mails MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Zyntra - Temp e-mails MCP need an API key?
