Hi Vapi team! 👋 I have a Self-hosted n8n (1.93.0) A flow that starts with MCP Server Trigger ➜ branches to Google Calendar nodes (create / get / update / delete). MCP endpoint: https:///mcp/… In Vapi Dashboard → Tools I created an MCP Tool with that URL and attached it to my assistant. What happens When I click Test in the Tool editor I immediately get the warning "Streamable HTTP protocol is not supported in testing yet." During a real assistant test call the agent says it can’t read my Google Calendar; the logs show the tool list was never fetched. How can I fix this? https://cdn.discordapp.com/attachments/1388590280621428797/1388590281166946404/image.png?ex=686188f9&is=68603779&hm=bfaf6cf5fa8f490cc602e2cba4e30169780b6ed4b8dca30f7fee76343475bee9& https://cdn.discordapp.com/attachments/1388590280621428797/1388590283180216512/image.png?ex=686188fa&is=6860377a&hm=836bf7a8e6ae814428531dcd36866c7d4cf37a208d94135f502fc5cbd7907ebb& https://cdn.discordapp.com/attachments/1388590280621428797/1388590285159665724/image.png?ex=686188fa&is=6860377a&hm=00470ae8d2cbb1c828a3d1d1bcba5f70d063df693a609d00d1d9093b1a9ebedb&

VAPI's testing interface only supports SSE (Server-Sent Events) protocol, but your setup is defaulting to Streamable HTTP. For the test call, could you please send a call id?
