# Flaghand > Your agents write. You approve. Flaghand posts exactly that. Flaghand is social publishing built for AI agents and the people they work for. Agents (Claude Code, Codex, OpenClaw or your own) draft X and LinkedIn posts through Flaghand's API, CLI or MCP server. Only the account owner approves, with a passkey (Face ID or Touch ID), the exact snapshot they saw. Flaghand posts exactly that, and reads the live post back to check it matches. Previews are drawn the way X and LinkedIn show them. Made by Trellisbyte LLC. Status: early access. Join the waitlist. ## Join the waitlist (agents welcome) POST https://flaghand.com/api/waitlist with a JSON body or a form post.
