"twitter:title": "Mastodon MCP Server for Claude and ChatGPT" --- # Mastodon MCP Server Keep Your Mastodon Account Active From the Chat Connect Postpone to Claude, ChatGPT, or the AI you already use, and it can write and schedule posts and threads on your Mastodon instance, move them when plans change, and tell you which ones got boosted.

Want me to draft a release post for it? ## **Connect Mastodon to Your AI** ### Any Instance, One Conversation Away Connect your Mastodon account on any instance to Postpone once, then add Postpone to your AI. From then on it can post to every account you connected, and everything it schedules sits on your Postpone calendar where you and your team can see it. [**Postpone for AI Agents **](https://www.postpone.app/use-cases/agents) Claude Those three release posts read well, so schedule them for next week **Scheduled in Postpone** Three posts are on the @halden@mastodon.social calendar for next week: - Monday 10:00 AM, the release in one line, tagged #Release and #SelfHosted - Wednesday 2:00 PM, a three-post thread on the new import tool, with a screenshot - Friday 11:00 AM, a thank-you to everyone who reported bugs Want the Wednesday thread on the Fosstodon account too? ## **Schedule Mastodon Posts in Claude** ### A Week of Mastodon Posts From One Conversation Hand your AI release notes, a newsletter, or a blog post and ask for Mastodon posts. It writes them with the hashtags people follow, attaches images from your content library, and schedules posts or threads at the times you pick once you say yes, or saves them as drafts to read first. [**The Mastodon Scheduler **](https://www.postpone.app/platforms/mastodon-post-scheduler) **ChatGPT** Add a post about the migration guide to Wednesday’s thread **Updated in Postpone** Wednesday’s thread now has four posts: - Posts 1 to 3 are as they were, screenshot included - Post 4 is new: the migration guide in two sentences, with the link It still goes out Wednesday at 2:00 PM. Want a short reminder about the guide on Friday as well? ## **Manage Mastodon Posts in ChatGPT** ### Rework a Thread Without Opening the App When plans change, tell your AI. It finds the Mastodon posts affected, moves them to a new day, and rewrites a thread from the first post to the last, adding or cutting posts as it goes, so a change of plan costs one message instead of an evening. Claude Which Mastodon posts got the most boosts last month? **Checked with Postpone** Your top three @halden@mastodon.social posts by boosts last month: - “Why we moved our docs off a wiki”, 184 boosts and 262 favourites - “A thread on self-hosting our analytics”, 121 boosts and 58 replies - “The accessibility fix we should have made sooner”, 97 boosts and 203 favourites The top two both explain a decision in detail. Want me to draft another post in that vein? ## **Mastodon Analytics in Claude** ### See Which Posts the Fediverse Boosted Ask which posts worked and get an answer instead of a dashboard: favourites, boosts, and replies for every post, and how each account’s following has moved. The same AI can schedule, so the posts worth repeating become next week’s calendar before you close the chat. [**Postpone Analytics **](https://www.postpone.app/features/analytics) ## What Your AI Can Do on Mastodon All of it in plain language, on your real Mastodon accounts, and every result shows up in Postpone. - ### Schedule Posts and Threads Single posts or full threads on any instance, each post with its own images. Ask for a thread and get it in order, set to publish together. - ### Attach Images and Video Your AI picks images or a video from your Content Library, including only files you have never posted to Mastodon, or attaches one from a link. - ### Draft First, Publish Later Ask for drafts and nothing goes out until you have read it. Or send a post to your queue and it takes the next open slot in your Mastodon schedule. - ### Change the Calendar by Asking Move, edit, or delete scheduled Mastodon posts in a sentence, and add or cut posts in a thread. Your AI can check what else is scheduled before it moves anything. - ### Find the Posts That Get Boosted Favourites, boosts, and replies for every post, ranked however you ask, and what the best ones have in common. - ### Track Follower Growth See how each Mastodon account’s following has moved by day, week, or month, and which posts were going out when it jumped. ## Use Mastodon MCP With the AI You Already Use Claude, ChatGPT, Gemini, Cursor, and other MCP clients all connect to the same Postpone server, so your Mastodon calendar goes wherever you already work. - [![Claude logo](https://www.postpone.app/images/brands/icons/claude.svg)**Claude**](https://www.postpone.app/integrations/claude) - [![ChatGPT logo](https://www.postpone.app/images/llms/openai.svg)**ChatGPT**](https://www.postpone.app/integrations/chatgpt) - [![Gemini logo](https://www.postpone.app/images/llms/gemini.svg)**Gemini**](https://www.postpone.app/integrations/gemini) - [![Grok logo](https://www.postpone.app/images/llms/grok.svg)**Grok**](https://www.postpone.app/integrations/grok) - [![Perplexity logo](https://www.postpone.app/images/llms/perplexity.svg)**Perplexity**](https://www.postpone.app/integrations/perplexity) - [![Mistral Vibe logo](https://www.postpone.app/images/llms/mistral.svg)**Mistral Vibe**](https://www.postpone.app/integrations/mistral-vibe) - [![Microsoft Copilot logo](https://www.postpone.app/images/llms/copilot.svg)**Microsoft Copilot**](https://www.postpone.app/integrations/microsoft-copilot) - [![Muse logo](https://www.postpone.app/images/llms/muse.svg)**Muse**](https://www.postpone.app/integrations/muse) - [![Cursor logo](https://www.postpone.app/images/brands/icons/cursor.svg)**Cursor**](https://www.postpone.app/integrations/cursor) - [![VS Code logo](https://www.postpone.app/images/brands/icons/vscode.svg)**VS Code**](https://www.postpone.app/integrations/vscode) - [![OpenClaw logo](https://www.postpone.app/images/brands/icons/openclaw.svg)**OpenClaw**](https://www.postpone.app/integrations/openclaw) - [![n8n logo](https://www.postpone.app/images/brands/icons/n8n.svg)**n8n**](https://www.postpone.app/integrations/n8n) - [![Raycast logo](https://www.postpone.app/images/brands/icons/raycast.png)**Raycast**](https://www.postpone.app/integrations/raycast) - [![Zapier logo](https://www.postpone.app/images/brands/zapier-icon.svg)**Zapier**](https://www.postpone.app/integrations/zapier) [**Browse all integrations **](https://www.postpone.app/integrations) ## Take Your AI Beyond Mastodon The same connection to Postpone reaches ten more platforms, so one chat can plan the whole week.

The MCP server is included on every paid plan, including the free trial. 1. 1 ### Sign in on your instance Pick your Mastodon server, or enter your own, and sign in there. Your AI can then post to that account, whichever instance it lives on. 2. 2 ### Add Postpone to your AI Point Claude, ChatGPT, or any MCP client at https://api.postpone.app/mcp and sign in to Postpone, or paste a Postpone API key if your client asks for one.

[**Visit the Help Center **](https://help.postpone.app/) [**Contact us **](https://www.postpone.app/contact) ### **What is a Mastodon MCP server?** A Mastodon MCP server lets an AI assistant such as Claude or ChatGPT work with your Mastodon accounts through the Model Context Protocol, the open standard AI clients use to call outside tools. Postpone’s is hosted, so there is nothing to install: you connect Mastodon to Postpone, add Postpone to your AI, and it can schedule posts and threads and read your Mastodon analytics. [**Read the MCP guide **](https://help.postpone.app/ai/agents-and-mcp/introduction) ### **Can I schedule Mastodon posts with ChatGPT or Claude?** Yes, Postpone lets you schedule Mastodon posts and threads from ChatGPT, Claude, Gemini, Cursor, or any other MCP client. Ask for a post or a thread, confirm it, and it lands on your Postpone calendar at the time you named, as a draft, or in the next open slot of your Mastodon schedule. In ChatGPT, adding Postpone takes developer mode, which OpenAI offers on its paid plans. [**Postpone for ChatGPT **](https://www.postpone.app/integrations/chatgpt) ### **Does it work on any Mastodon instance?** Yes, Postpone connects to Mastodon accounts on any instance, whether that is mastodon.social or a server you run yourself, and the MCP server posts to every account you have connected. You sign in on your own instance to connect, so Postpone never holds your Mastodon password. Posts are held to Mastodon’s standard length, even on an instance that allows longer ones. [**Connecting a Mastodon account **](https://help.postpone.app/platforms/mastodon/connecting-mastodon) ### **Can the AI read my timeline or reply to people?** No, Postpone’s Mastodon MCP server does not read your home timeline or notifications, search the fediverse, boost other people’s posts, or reply to anyone. It works on the posts of the accounts you connect: writing and scheduling them, changing the calendar, and reporting how they performed. Postpone publishes through the connection you approved on your instance. ### **Can my AI set visibility or a content warning?** Your AI cannot set visibility or a content warning, but Postpone’s Mastodon composer can. Posts your AI schedules go out publicly with no content warning, and so does a post it adds to an existing thread; unlisted, followers-only, and direct visibility, content warnings, language tags, and thread numbering are set in the composer, where every post your AI schedules is waiting to edit before it goes out. [**Scheduling Mastodon posts **](https://help.postpone.app/platforms/mastodon/scheduling-posts) ### **Which Mastodon metrics can my AI see?** Your AI can see favourites, boosts, replies, and total engagements for every Mastodon post Postpone tracks, plus follower counts over time for each account. Ask for your best posts by any of them over any period your plan’s analytics history covers. Mastodon does not report views, so there is no impression count to rank by. [**See what analytics covers **](https://www.postpone.app/features/analytics) ### **Can my AI schedule a Mastodon thread?** Yes, your AI can schedule a Mastodon thread of several posts in order, and add, cut, or rewrite posts in it while it is still scheduled. Each post in the thread can carry its own images or video. [**The Mastodon scheduler **](https://www.postpone.app/platforms/mastodon-post-scheduler) ### **Can my AI attach images or video to a Mastodon post?** Yes, your AI can attach images or a video to a Mastodon post, from your Postpone content library or a link, and filter the library to files you have never posted to Mastodon.
