Post to social media from Claude
Connect PostJay to Claude over MCP and just say what to post. Claude drafts your captions and schedules to 13 platforms — no dashboard, no copy-paste.
Claude is great at writing posts — but it can't publish them. PostJay closes that gap. It exposes a Model Context Protocol (MCP) server that Claude connects to, turning "write me a LinkedIn post" into "write it and schedule it for 9am," done in one message.
Once connected, Claude can list your accounts, draft on-brand captions, and schedule or publish across all 13 networks — right from Claude Desktop or claude.ai. You stay in control: Claude proposes, you confirm, PostJay posts for real through each platform's official API.
Why post from Claude with PostJay
Native MCP connection
PostJay ships a real MCP server (not a screen-scraper). Add it once in Claude and the scheduling tools appear — list integrations, draft, schedule, publish.
Claude drafts, then posts
Ask Claude to write a thread and schedule it. It uses your brand voice, then publishes to the platforms you pick — no switching to a dashboard.
13 platforms, real publishing
Posts go out for real to Instagram, TikTok, YouTube, LinkedIn, Facebook, Pinterest, Threads, Bluesky, X, Mastodon, Discord, Telegram and Tumblr via each platform's official API — with per-platform formatting, not one blast.

Claude + PostJay FAQ
