What's Wrong?

When using the Xcode MCP tools with the Claude Code Desktop app in the "Code" tab, macOS shows an Automation permission dialog ("Allow local-agent-mode-xcode to access Xcode?") on every single tool invocation. Clicking "Allow" does not persist the permission — the dialog reappears on the next call.

The Automation panel in System Settings > Privacy & Security > Automation remains empty, confirming macOS is not saving the grant.

Root Cause

The disclaimer helper binary at /Applications/Claude.app/Contents/Helpers/disclaimer has a generic code signing identifier:

Identifier=disclaimer

macOS TCC keys Automation permissions by the client binary's code signing identifier. Because this is a bare name rather than a reverse-DNS bundle ID (e.g., com.anthropic.claude.disclaimer), TCC does not persist the permission entry.

What Should Happen?

Clicking "Allow" should persist the Automation permission so the user is not re-prompted.

Claude says the fix is to
Give the disclaimer helper (or whichever binary sends Apple Events to Xcode) a proper reverse-DNS bundle identifier so macOS TCC can persist the Automation permission.

Error Messages/Logs

Allow "local=agent-mode=xcode" to access Xcode?

The agent "local-agent-mode-xcode" at /Applications/Claude.app/Contents/Helpers/disclaimer, PID [redacted], wants to use Xcode's tools to perform actions like building, testing, or modifying code.

Don't Allow | Allow
