Auto-mode telemetry now tags MCP tool calls with which server they connect to and whether that's ambiguous

What

When Claude Code's auto-mode (a mode that can approve or reject tool calls automatically) logs telemetry about falling back to asking the user, making a decision, or showing a permission prompt, calls involving an MCP tool (one provided by a Model Context Protocol server) now get extra information attached: which server connection the tool belongs to, and a flag for whether that association is ambiguous. This is computed only when needed and reused for the rest of that call.

Why

This gives clearer visibility into how auto-mode handles MCP tools specifically, which is useful since a tool name alone doesn't always identify which server it came from.
