Triggers that publish to Mastodon
Native formatting
Posts that look native, not pasted
Cross-posting the same text everywhere produces broken Mastodon posts — truncated mid-word, missing media, wrong aspect ratio. Feedloop reshapes the post to Mastodon's native format before it ships. Specific to Mastodon: 500 chars body, image + video.
Over Mastodon's character limit — gets cut mid-word.
Auto-truncated at word boundaries, native media, char count handled.
Any source
Wire any source to your Mastodon
RSS feeds, a WordPress webhook, a connected social account, a CSV upload, an AI assistant via MCP, or the in-dashboard composer. Whichever trigger fires, the post lands on Mastodon formatted natively.

FAQ
Mastodon auto-poster questions
- Does Feedloop really publish directly to Mastodon?
- Yes — we use Mastodon's official API, not a browser automation hack. Your post lands the same way it would if you'd opened the Mastodon app and tapped Publish.
- Do I need a Mastodon business account?
- No. Any active Mastodon account works. Just connect it once via OAuth.
- What does it cost to schedule Mastodon posts with Feedloop?
- Feedloop has a free tier you can use to schedule Mastodon posts. Paid plans unlock higher volume and additional connected accounts. We accept USD via Polar and Ethiopian Birr via Telebirr.
- Can I auto-post to Mastodon from an RSS feed?
- Yes — text-only RSS items publish fine, and Mastodon happily accepts a featured image if your feed includes one (most do via <media:content> or the first <img> in the description). When publishing does happen, Feedloop auto-truncates at word boundaries to fit Mastodon's character limit and dedupes by feed item ID so the same entry never ships twice.
- How is this different from Buffer, Hootsuite, or dlvr.it for Mastodon posting?
- Buffer is composer-first — you still write every Mastodon post by hand. Hootsuite is enterprise-priced with team workflows we don't try to match. dlvr.it has the same RSS-first shape Feedloop does but no MCP support. Feedloop's wedge is RSS-driven automation + native Mastodon formatting + a Model Context Protocol server that lets Claude / ChatGPT / Cursor / Gemini drive your Mastodon pipeline directly.
- Can Claude or ChatGPT schedule Mastodon posts for me?
- Yes. Feedloop exposes its publishing tools through the Model Context Protocol (MCP), so any MCP-compatible AI client — Claude (web, desktop, code), ChatGPT, Cursor, Gemini, Windsurf, VS Code, Cline, Codex, LM Studio, Cherry Studio, Jan, AnythingLLM — can draft and schedule Mastodon posts on your behalf. You authorize the connection once and the assistant can queue, reorder, or publish to Mastodon without you switching tabs.
- What happens if a Mastodon post fails to publish?
- The worker retries with exponential backoff before surfacing the failure for manual review. You'll see the exact Mastodon API error message in the queue and can either retry, edit the post, or remove it. Token-expiry failures auto-trigger a refresh through OAuth — you only get a re-auth prompt when the refresh itself fails.
