Build the connectors at https://clono.sh/connectors/mailboxvalidator and https://clono.sh/connectors/clono.Build a connector from https://clono.sh/connectors/mailboxvalidator/mcp. Use only this address for every call; don't look MailboxValidator up anywhere else. It signs in with OAuth, not an API key: authorize URL https://auth.tendle.ai/mailboxvalidator/authorize, token URL https://auth.tendle.ai/token, dynamic client registration at https://auth.tendle.ai/register, scopes `mcp`, PKCE with S256, as a public client with no client secret. Then also build the Clono connector from https://clono.sh/connectors/clono/mcp. It needs no sign-in, and it finds more connectors when a task needs one. Tell me when both are built.If your agent says it couldn’t connect, try again. Sign-in sometimes takes a second try.
