WebRTC Transport for Model Context Protocol

WebRTC Transport for Model Context Protocol

There are scenarios where neither STDIO nor StreamableHTTP transport can be used to connect an MCP client to an MCP server. WebRTC can often be used instead if there is some sort of signalling connection established between the two parties.

Usage

    from mcp_webrtc import webrtc_server_transport
    from aiortc.contrib.signaling import CopyPasteSignaling

    async with webrtc_server_transport(CopyPasteSignaling()) as (read, write):
        app.run(
            read, write, app.create_initialization_options()
        )

    from mcp import ClientSession
    from mcp_webrtc import webrtc_client_transport
    from aiortc.contrib.signaling import CopyPasteSignaling

    async with (
        webrtc_client_transport(client_signaling) as (
            read,
            write,
        ),
        ClientSession(read, write) as session,
    ):
        await session.initialize()
        result = await session.list_tools()
        print(result.tools)
