What HTTP Streamable transport for MCP connections not working Why Current SSE method is deprecated (March 2025 spec)

{ "name": "get_free_slots", "role": "tool_call_result", "time": 1750233188585, "result": "{\"error\": \"Failed to connect to MCP server\"}", "toolCallId": "call_nJDAv4V3JY3pGC5TVlKegV4V", "secondsFromStart": 30.743 }

When you click on the API logs and then click on a specifc API the popup on the right has unreadable header and the colors are always in dark mode.

The headers in the docs do not seem to be currently included in VAPI's MCP agent requests. I'm using the MCP tool with a Xano MCP server. The content interaction is working AMAZING. This is a great feature. However, I'm not getting any call/assistant info from VAPI with the MCP requests. VAPI's MCP agent docs note that the following headers should be sent with MCP agent requests from VAPI: X-Call-Id, X-Chat-Id, X-Session-Id Those requests are not coming over in the headers and this is what I believe is the bug. tool id: 0706532a-2b88-48b2-bab1-5eb482703939

when i tell the assistant to book meeting at tomorrow 2pm then without sending the rigt time and date which is 22 june 2025 but he send date of 2023, which is too old

Issue: Call Logs Export Bug Steps to Reproduce: Go to Call Logs page Apply a date filter (example: filter calls for this week) The system detects 1346 calls (correct result) Click Export, and VAPI displays message: “Download link will be emailed to you” Download the emailed link → CSV file is generated Problem: The CSV file is empty — it only contains column headers, no call records Additional Notes: If I do not use filters, the export works fine — I receive a file with correct call data However, exporting without filters is inefficient because the Call Logs page only displays 100 calls, so filtering is needed to get full results for a date range.

My users are getting a busy signal. I upgraded my plan to allow 50 concurrent callers. I know I have more than one simultaneous caller but much less than 50. What is the problem?

I had added my Twilio number to Org A. Now I have removed it, but I am unable to add it to Org B. I receive error "The number is being used by another org."

bug "N/A" "This is the data extracted based on the Conversation." https://dashboard.vapi.ai/calls/0823d806-72d0-4ce6-ab95-581ed1dc23e7 . Data extraction hasn’t been working at all for a month or even longer. What’s going on?
