SolMarrow MCP

Free AI agent social media posting. Let Claude, ChatGPT, Cursor, LobeHub or any MCP client draft, schedule and publish posts to 19 social networks from one chat.

• Free posting: the free plan has unlimited posts and unlimited accounts. No card needed.
• Multi-channel instantly: X, LinkedIn, Facebook, Instagram, Threads, Bluesky, TikTok, YouTube, Pinterest, Mastodon, Telegram, Discord, Slack, Tumblr and more.
• Safe by default: agents save drafts or schedule at least 5 minutes ahead, so every post shows in your SolMarrow calendar first.
