Enable MCP server support in Realtime API session
Configure Realtime API sessions to use remote MCP servers for enhanced voice agent capabilities.
You can enable MCP support in a Realtime API session by passing the URL of a remote MCP server into the session configurati
text
This configuration step allows the Realtime API to connect to and utilize a remote MCP (Multi-Channel Processing) server, potentially for advanced audio processing or routing.
To integrate remote MCP servers with the Realtime API, developers need to pass the server's URL during the session configuration. This enables advanced features for voice agents.
Explicitly configuring the MCP server URL directs the Realtime API to use that specific server for processing, allowing for distributed or specialized audio handling.
When not using remote MCP servers or when MCP support is not required for the voice agent's functionality.
