Post to Instagram with Publora

Instagram Post via Publora creates and schedules Instagram content - single-image posts, 2-10 image carousels, Reels, and Stories - through the Publora MCP server, with a REST API fallback if the MCP connection has issues. It wraps Instagram's Graph API, which has its own constraints distinct from the native app: images must be JPEG (PNG/GIF/WebP are rejected), Reels can run up to 15 minutes (though only 5-90 seconds are eligible for the Reels tab), Stories and carousel videos cap at 60 seconds, and captions are limited to 2,200 characters with only the first 125 shown before "more."

Use it to publish or schedule Instagram content programmatically - a product screenshot carousel, a tutorial Reel, a 24-hour Story, or a caption scheduled for a specific time. It only works with an Instagram Business account; Personal and Creator accounts are rejected outright by the underlying API. Every post needs at least one image or video - Instagram has no text-only post type through this API - and a carousel must be all images or all videos, never mixed. Rate limits cap out around 50 posts per 24 hours (some accounts see 25).

Setup: create a free Publora account, convert the target Instagram account to Business in Instagram's own settings, connect it via OAuth in the Publora dashboard, generate an API key, and add an MCP server entry pointing at https://mcp.publora.com with Authorization: Bearer YOUR_API_KEY. The core tool is create_post, taking a platforms array (e.g. ["instagram-11223344"]), content (the caption), and a required scheduledTime in ISO 8601 (use current time + 1 minute for near-immediate posting); get_upload_url fetches a presigned URL for attaching media, requiring contentType to be exactly image/jpeg or video/mp4; list_posts, update_post, and delete_post manage existing posts. Video type (Reels vs. Stories) defaults to Reels and can only be switched to Stories via the REST API's platformSettings.instagram.videoType, since that field isn't exposed through MCP.

If the MCP server is unavailable, the same operations are reachable directly over REST at https://api.publora.com/api/v1, authenticated with an x-publora-key header rather than Authorization: Bearer. Publora plans gate volume rather than features: the free Starter tier allows 15 posts/month, Pro allows 100/account/month for $2.99, and Premium allows 500/account/month for $9.99.

Social media managers, marketers, and indie builders who want an AI assistant to publish and schedule Instagram Business content - images, carousels, Reels, and Stories - directly, while automatically respecting the Graph API's stricter-than-native format and rate limits.
