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.
Plan Mastodon posts in Notion.
Native two-way sync. Your Notion calendar is the source of truth — every row that gets a Mastodon channel and a Scheduled date ships through Feedloop. Edits in Notion flow back into the queue. After publish, the row updates with the live URL.

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 I plan Mastodon posts in Notion and have Feedloop publish them?
- Yes. Feedloop has native two-way Notion sync — duplicate the free Feedloop Content Calendar template (or connect an existing Notion calendar), tag each row with Mastodon as a channel and a Scheduled date, and Feedloop turns each row into a real Mastodon post on schedule. Edits in Notion flow back into the queue within ~60 seconds via Notion's webhook (with a 5-minute poll fallback). After publish, the row's status flips to Published and the live Mastodon URL writes back into the row. No Zapier in the middle, no 5-step setup, and it's free on every Feedloop plan.
- 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.
- Can I see which Mastodon posts actually work? What stats does Feedloop give me?
- Yes — the Deeper insights tab exposes 22 statistical cuts specifically built for content optimization. For Mastodon, the most useful are: caption sweet-spot (which caption length range gets the best engagement rate on Mastodon specifically), hashtag sweet-spot (the optimal hashtag count per post for Mastodon), engagement rate across 3 denominators (reach, impressions, followers), posting-time heatmap (7×24 grid showing when Mastodon engagement is highest for YOUR audience), and a bait classifier that flags posts whose engagement spikes correlate with low-quality interactions. The same insights are available as MCP tools so Claude / ChatGPT can pull "what caption length should I use for Mastodon?" directly into the chat. On Pro you can also schedule a white-label PDF report with your logo and brand color, delivered monthly to your inbox.
- 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.
