Defense-in-depth repo scope enforcement for the GitHub MCP proxy: - Default-deny for unknown tools (allowlist of known tools) - Search query scoping: auto-inject repo:OWNER/REPO, block org:/user: qualifiers - Block non-repo-scoped tools (search_users, search_orgs, get_teams, etc.) - Inject owner/repo when tools omit them - Server-side tool filtering via X-MCP-Toolsets/Tools/Readonly/Lockdown headers - Sensible default toolsets: repos,issues,pull_requests,git,labels - Lockdown mode enabled by default - VM cannot override X-MCP-* headers - Skip body re-serialization when unmodified Also adds GitHub App token generation scripts and comprehensive tests (unit + end-to-end with mock upstream server).

- Remove unused github_app_token.sh (only github_app_token_demo.py is used by claude-vm.sh) - Document token generation flow: GitHub App device flow with repository_id scoping - Rename "Security layers" to "Defense-in-depth" to clarify these are additional layers on top of GitHub's token scoping Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The VM is already sandboxed, so the interactive confirmation for --dangerously-skip-permissions is unnecessary. Pass IS_SANDBOX=1 env var when launching claude CLI. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
