A Buffer alternative built for the way people work with AI now
Buffer made scheduling simple and it is still good at that. PostMCP AI keeps the queue and the calendar, then adds the two things a scheduler built before agents could not have: an AI that writes per network, and a protocol server your own assistant can call.
Three differences that actually change your day
An agent that writes, not a box you type into
Classic schedulers are a composer and a queue: you supply every word. PostMCP ships an AI agent that reads your brand kit, drafts a different version per network, generates a matching image, dry-runs the result and proposes a schedule — and then waits for your approval.
Your own AI can drive it
PostMCP is also a Model Context Protocol server. Claude, ChatGPT or Cursor can call the same sixteen publishing tools your dashboard uses. If you have already built a workflow around an assistant, publishing plugs into it rather than sitting outside it.
Per-profile truth instead of a single status
A post to five profiles is five deliveries, each with its own status, permalink and upstream error. Retrying re-sends only what failed. You are never left with one green tick covering two networks that quietly dropped it.

This page describes what PostMCP AI does. Competing products change their plans and features regularly — check their current documentation before you decide, and switch on the strength of your own comparison rather than ours.
PostMCP is probably the better fit if…
- ✓You want AI to draft the posts, not just schedule them
- ✓You already work inside Claude, ChatGPT or Cursor and want publishing there
- ✓You are on Bluesky or Threads and want them treated as first-class
- ✓You want to publish from a script, a CI job or your own product
- ✓You run several clients and want hard separation, not folders
Stay where you are if…
- –You need deep native analytics and reporting dashboards as the core product
- –You depend on a large third-party integration marketplace
- –Your team is trained on a workflow that already works and nobody is asking for AI
- –You need networks PostMCP does not support yet, such as Pinterest or TikTok
Switching questions
What is the best Buffer alternative with AI?+
It depends what you want AI to do. If you want it to suggest a caption, most schedulers now do that. If you want an agent that reads your brand kit, writes a different post for each network, generates the image, checks every limit and proposes a week of slots — and that your own Claude or ChatGPT can drive directly — that is the gap PostMCP AI was built to fill.
Can I schedule to Bluesky and Threads?+
Yes, both are first-class. Bluesky counts by grapheme rather than byte and works against self-hosted AT Protocol servers as well as bsky.social. Threads publishes through the linked Instagram identity. Neither is a bolt-on.
Does PostMCP have a free plan?+
Yes — Free Forever, with 5 connected profiles, 20 publishing credits and 100k AI tokens per month, plus the full drag-and-drop calendar. No card to start.
How is publishing priced?+
By delivery rather than by seat: 1 credit per profile you publish to, 5 for X, plus a one-off 50-credit surcharge on posts containing a link. Plans bundle credits monthly and one-time packs top them up. A dry run tells you the cost before you commit.
Can I migrate my scheduled posts?+
There is no automatic import from other schedulers. Connect your accounts, and either re-create your queue in the calendar or push it in through the API — the create_post endpoint takes a date, a time and a timezone, so a scripted bulk import is a short job.
Do I need to use the AI at all?+
No. The composer and calendar work exactly as a manual scheduler, and the AI tokens simply go unspent. Plenty of people use PostMCP as a plain multi-network scheduler and turn the agent on later.
