RealTime API SIP problem with MCP Server

I set up a realtime API prompt with a SIP connection.

Everything works fine except for the MCP servers. Basically, when I test the prompt from the platform, it works fine. However, if I use it from the SIP connection in the socket, I get an error.

{“type”:“mcp_list_tools.failed”,“event_id”:“event_CIfv69R3WvHbbBSDzzkX3”,“item_id”:“item_CIfv4mMBzO254X3xV7HP5”}

If I try it from the platform dashboard, it works fine.

All other settings in the saved prompt, including the “functions,” work!

Any idea? Is it a bug?

do you see any traffic to your MCP server when using it with SIP?

No… no message… no traffic
