Unclear It is not clear how registering an aliased tool changes the way the classifier checks its calls.
What
Auto mode is a permission mode in which Claude Code uses a classifier, an automatic safety check, to decide whether each tool call can run without asking you. Claude Code now has a step that looks at your toolAliases, which are alternative names that point at a tool.
An alias that points at an MCP tool name (an MCP tool comes from an external server and is named in the form mcp__server__tool) gets that tool registered.
An alias that points at a tool from an SDK-created MCP server running with CLAUDE_AGENT_SDK_MCP_NO_PREFIX, which drops the mcp__<server>__ prefix from tool names, also gets the tool registered.
For any other alias, Claude Code logs a warning that an allow rule for that tool still runs its calls without the classifier's check.
This step is off unless it is switched on remotely.
Why
Tools reached through an alias could slip past the auto mode check. The warning tells you when an allow rule you wrote means a tool's calls are not being checked.
Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
