Mastodon from any device
The connector belongs to your Claude account rather than a machine, so the same Mastodon tools answer on the web, on the desktop and in the phone apps.
MastodonAutomate Mastodon with Claude
Ask Claude for Mastodon posts and it schedules them through postqueen. Add the connector once on the web and the same tools answer on your phone.
Quick start
Add postqueen as a connector on claude.ai and Mastodon scheduling is available in every chat, including the phone apps.
MCP supportedCustom connector
# claude.ai, Settings, then Connectors# Add a custom connector: https://api.postqueen.ai/mcp/YOUR_API_KEY # Then ask:# "Draft three Mastodon posts for this# week and put them on the calendar"What Claude can run on Mastodon
Windows that fit Mastodon
Tell Claude when your followers are most active and it schedules posts into that window on Mastodon, day after day, without reminders.
Media attached, sized right
Images upload in the same postqueen call, so Mastodon posts arrive with their media in place instead of a bare link.
Drafts until you are ready
Ask Claude for drafts only. They sit on the postqueen calendar unscheduled, so you can edit them and pick the time yourself, and nothing reaches your followers on Mastodon until you do.
Three steps to a full queue
Discover Mastodon
Claude calls postqueen to list your connected instances and accounts and sees what Mastodon supports, so drafts start from real capabilities, not guesses.
Draft with Claude
Give it the brief. The agent writes Mastodon-shaped posts and proposes publish times that match when your followers are around.
Check and publish
Look over the queue on the postqueen calendar and change anything you want. postqueen publishes each post at its time, and Claude can pull the results after.
What Mastodon allows
Claude reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.

F.A.Q.
Frequently asked questions
How does Claude connect Mastodon to postqueen?
Over MCP, as a custom connector added once on claude.ai. Claude has no terminal, so there is no CLI to install: the connector carries your API key and the Mastodon tools then answer in the desktop and phone apps too.
Can Claude schedule Mastodon posts at exact times?
Yes. Give it exact slots or a rule like mornings at nine and it sets publish times on the posts it creates, so your followers see them at the right moment.
Will Claude publish to Mastodon on its own?
Only if you ask it to. Tell it to save drafts and nothing is scheduled: the posts wait on the calendar until you set a time. Tell it to schedule, and they go out at the times you can see, which is the setup most people move to once they trust the output.
Can one brief cover Mastodon and other channels too?
Yes. postqueen connects 30 channels, so Claude can turn the same brief into Mastodon posts plus adapted versions for every other channel you run.
Does Claude access cost extra on postqueen?
No. The agent uses your regular API key and plan limits: unlimited posts on every plan, and channel counts from 5 on Creator up to uncapped on Ultimate.
Why did my scheduled Mastodon post fail?
Common causes are media above your server's upload limits, a server character limit lower than your draft, a revoked token, or the instance being temporarily down. Fix the post or reconnect the account and schedule it again.
Can I try Mastodon scheduling for free?
Yes. Cloud plans start with a 7-day free trial and unlimited posts. And since postqueen is open source under AGPL-3.0, self-hosting is free if you would rather keep everything on your own infrastructure.
