Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Diagnose a sanitized HTTP 401 authentication failure without accepting credentials or contacting the target endpoint.
Only scheme, host and path are retained; query and fragment are discarded.
This tool isn't marked read-only, so it may change something on the server or in an account you connected.
