Uses handleTool helper to authenticate and call Gmail API's users.settings.forwardingAddresses.get method.
async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.forwardingAddresses.get({ userId: 'me', forwardingEmail: params.forwardingEmail }) return formatResponse(data) }) } - src/index.ts:1091-1093 (schema)Input schema for get_forwarding_address tool requiring a single 'forwardingEmail' string parameter.
