- Represents MCP servers in customizations and allow their state/ authentication requirements to be reflected. - Breaking: swap `ToolCallBase.clientId` -> `ToolCallBase.contributor` to allow signalling tool calls were triggered by particular MCP servers. - Add additional ToolCallBase._meta note for MCP servers and introduce the `mcp://` protocol channel. This should support all the base features of MCP + MCP Apps, excluding sampling, which is deprecated in the upcoming 2026-07-28 MCP spec and therefore not something I bothered including.
