Smoke run 3 showed agents loading builtin Anthropic connectors
(mcp__claude_ai_Gmail__authenticate, Google Calendar, Notion, Drive)
alongside our 5 roboco MCP servers. The connectors bloat the tool
surface and give the LLM 'discover' targets it shouldn't have.
The Claude Code CLI's --strict-mcp-config flag tells it to load ONLY
the servers from --mcp-config, ignoring all builtin defaults. Added
to _append_image_and_claude_args next to --mcp-config.
Note: the existing --tools allowlist (Read,Write,Edit,Bash,Grep,Glob,
Task,TodoWrite) only filters builtin tools, not MCP-prefixed ones —
that's why the connectors slipped through.
