MCP tool-surface drift check: compare a pinned baseline (tool fingerprints) against the live surface (JSON-RPC tools/list, SSE-aware, well-known fallback) or an inline current_tools. Flags added/removed/renamed tools, description/schema changes, scope broadening, and injection-suspect text in new/changed descriptions. Signed verdict. $0.01.
