A social media API for AI agents: design the post and publish it, not just write the caption.
Most social APIs an agent can reach will publish text and pre-made media. PostNitro gives it the design engine: on-brand carousels, single-image posts and animated video built from 100+ templates and your brand kit — then scheduled and published natively to LinkedIn, Instagram, TikTok, Threads, Facebook and Pinterest. One chain, no human in the loop unless you want one.

How it works
From one prompt to a published post
Connect your agent
Add PostNitro to Claude or ChatGPT in one click, with no API key. Or point any MCP client, the CLI or the REST API at it.
Ask for a post
“Turn this article into a 6-slide LinkedIn carousel on our brand kit and schedule it for Thursday 9am.”
Approve it, or let it run
It's designed on your brand kit, then scheduled. Or it's saved as a draft on your calendar so you can review it and hit schedule.
Try it
Prompts to paste into your agent
“Turn my latest blog post into a LinkedIn carousel.”
“Announce our launch as an Instagram post on my brand kit.”
“Make a 20-second TikTok video from these five tips.”
“Plan next week: three carousels, Monday to Wednesday at 9am. Save them as drafts for me to review.”
Six ways in
The same engine, however you drive it
Claude
Listed in Claude's Connector Directory. OAuth, so there is no API key to fetch.
ChatGPT
Listed in ChatGPT's plugin directory. Same OAuth sign-in, same engine.
MCP server
Point any MCP client at mcp.postnitro.ai and the whole engine is callable.
CLI
JSON in, designed post out. Script-safe, built for CI and automations.
REST API
The layer the others are built on. Designs and publishes in one chain.
SKILL
npx skills add postnitro/postnitro-agent, and your agent drives PostNitro end to end.
The handoff
Agent drafts it. You finish it.
Capabilities
What the 35 tools actually cover
Create
Generate carousels, single-image posts and short video from a topic, raw text, an article URL, or an X post. Add AI-generated images and bake them into slides.
Import
Bring your own slide content and let PostNitro design it — same templates, same brand kit, no AI writing step.
Brand
List, read, create and update brand kits: fonts, colours, logos and headshots, so output is on-brand without a prompt describing it.
Schedule & publish
Create, read, update and delete scheduled posts. Connect and inspect social accounts. Publish natively to six networks.
Browse
List templates, AI presets and audio tracks, then pick deliberately instead of accepting a default.
Long jobs
Every generator has a fire-and-forget form and an and-wait form, plus status and output polling — so an agent can choose between streaming and blocking.
Access
One key, every interface
Agent access is included in Creator+ ($30/month, 200 credits/month) and Team+ ($60/month, 500 credits/month). On Starter, add it for $10/month (250 credits). Start with a trial →
