xint-mcp-must-specify-engagement-policy
xint MCP server defaults to read_only policy when registered without explicit --policy flag, silently blocking all Phase 2b write operations (like, bookmark, follow, block, mute, engage). Must register with claude mcp add -s project xint -- /usr/local/bin/xint mcp --policy engagement to enable full OAuth write capability. Add this to the session startup hook for auto-registration since xint MCP is project-scoped and wiped at session close.
