Instagram Post

Create and schedule Instagram posts using the Publora MCP server. Supports image posts, carousels (2-10 images), Reels, and Stories. Requires an Instagram Business account.

Prerequisites

Plans: Free Starter (15 posts/month), Pro, Premium

Getting Started

1. Create account at publora.com/register (free)
2. Convert to Business account in Instagram settings (Personal and Creator accounts are NOT supported by the API)
3. Connect Instagram via OAuth in Publora Dashboard
4. Get API key at publora.com/settings/api
5. Configure MCP in Claude Desktop (~/.claude/claude_desktop_config.json):

{
  "mcpServers": {
    "publora": {
      "type": "http",
      "url": "https://mcp.publora.com",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

REST API Fallback

If the MCP server is unavailable or returns errors, use the REST API directly:

Base URL: https://api.publora.com/api/v1

Authentication: Use x-publora-key header (NOT Authorization: Bearer):

# Get your connected platforms
curl -X GET "https://api.publora.com/api/v1/platform-connections" \
  -H "x-publora-key: sk_your_api_key"

# Create a post
curl -X POST "https://api.publora.com/api/v1/create-post" \
  -H "x-publora-key: sk_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "platforms": ["instagram-11223344"],
    "content": "Your caption here #hashtag",
    "scheduledTime": "2026-03-25T10:00:00Z"
  }'

Platform ID Format: instagram-{id} where {id} is from /platform-connections response.

Example IDs: instagram-11223344, instagram-55667788

Video Type Settings (via REST API)

Control how videos are published via platformSettings:

{
  "platformSettings": {
    "instagram": {
      "videoType": "REELS"
    }
  }
}

Note: platformSettings is not available via MCP - use REST API for video type control.

Examples

Single Image Post

Post this to Instagram:
"Morning coffee and code. Best way to start the day. #devlife #coding"

[Attach JPEG image]

Important: Image must be JPEG format. PNG will be rejected.

Carousel Post

Create an Instagram carousel with these 5 product screenshots.
Caption: "Our app evolution over 6 months. Swipe to see the journey! #buildinpublic"

Note: Requires 2-10 JPEG images. Cannot mix images and videos in carousels.

Reel

Post this video as a Reel:
"60-second tutorial on our new feature. #tutorial #app"

Videos default to Reels. Set videoType: "STORIES" via REST API for Stories.

Story

Post this 30-second clip as a Story (will disappear after 24 hours).

Requires platformSettings.instagram.videoType: "STORIES" via REST API.

Scheduled Post

Schedule this for tomorrow at 10 AM:
"New feature announcement coming soon! Stay tuned."
[Attach JPEG image]

Important Restrictions

1. JPEG only for images: PNG, GIF, WebP are NOT supported by the Instagram API. Convert to JPEG before uploading.

2. Business account required: Personal and Creator accounts cannot post via API. Only Business accounts work.

3. Media required on every post: Instagram does not support text-only posts. Every post needs at least one image or video.

4. No mixed media in carousels: A carousel must be either all images OR all videos (via separate posts), not both.

5. Stories disappear: Stories are ephemeral and disappear after 24 hours.

6. Reel is the default: Videos are published as Reels by default. To post a Story, use the REST API with videoType: "STORIES".

Best Practices

Content

1. First 125 chars matter: This is what users see before tapping "more"
2. Hashtag strategy: Use 5-15 relevant hashtags (max 30)
3. Image quality: Use high-quality JPEG images for best results
4. Carousel engagement: Carousels get higher engagement than single images

Timing

• Best times: 11 AM - 1 PM, 7 PM - 9 PM in target timezone
• Frequency: 1-2 posts per day for growth
• Reels boost: Reels get algorithmic preference over static images

Engagement

• Reply to comments within the first hour
• Use location tags when relevant
• Cross-promote from Stories to Feed
