@mcp.tool() @require_permission("mi.read") async def b2b_sca_list(ctx: Context) -> dict[str, Any]: """List active Shared Call Appearance (SCA) subscriptions.""" app = ctx.request_context.lifespan_context return await app.mi_client.execute("b2b_sca_list") - src/opensips_mcp/mi/commands.py:239-239 (registration)Registration entry for the 'b2b_sca_list' MI command via the _r() helper, describing it as belonging to the 'b2b_sca' module with 'List SCA subscriptions' description and default 'mi.read' permission.
_r("b2b_sca_list", "b2b_sca", "List SCA (Shared Call Appearance) subscriptions", category="b2b_sca") - The _r() helper function used to register MI commands into the MI_COMMANDS registry. It creates an MICommand dataclass instance and stores it in the global dictionary.
