\n

Instagram Post

\n

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.

\n

Prerequisites

\n

Plans: Works on the free Starter plan. Current limits and pricing: publora.com/pricing.

\n

Getting Started

\n
    \n
  1. Create account at publora.com/register (free)
    2. \n
  2. Convert to Business account in Instagram settings (Personal and Creator accounts are NOT supported by the API)
    3. \n
  3. Connect Instagram via OAuth in Publora Dashboard
    4. \n
  4. Get API key at app.publora.com/dashboard/api
    5. \n
  5. Connect your agent to the MCP server at https://mcp.publora.com, authenticating with Authorization: Bearer sk_YOUR_API_KEY. In Claude Code:
    6. \n
\n
claude mcp add publora --transport http https://mcp.publora.com \\\n  --header \"Authorization: Bearer sk_YOUR_API_KEY\"\n
\n

Claude Desktop, Cursor, Codex, OpenClaw and the claude.ai connector each need a different config file or flow: see client setup for the exact path and snippet.

\n

REST API Fallback

\n

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

\n

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

\n

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

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

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

\n

Example IDs: instagram-11223344, instagram-55667788

Platform Limits (API vs Native App)

\n

These limits are specific to the Instagram Graph API and differ from native app limits:

Available Tools

\n

create_post

\n

Create a new Instagram post.

\n

Parameters:

\n\n

get_upload_url

\n

Get presigned URL for media uploads.

\n

Parameters:

\n\n

complete_media

\n

Finalize a file uploaded through get_upload_url, after the presigned PUT succeeds. Optional, because scheduling also finalizes pending media, but calling it early surfaces format and probe errors before publish. Not needed for media attached with mediaUrls.

\n

Parameters:

\n\n

list_connections

\n

List your connected accounts with their platform IDs. Call this first and copy the IDs verbatim; they are never guessable.

\n

list_posts / get_post / update_post / delete_post

\n

Manage scheduled and draft posts. update_post also patches content and platforms on a draft or scheduled post, so fixing a typo or retargeting no longer means delete and recreate. delete_media and prune_media_reference clean up uploaded files.

\n

Video Type Settings (via REST API)

\n

Control how videos are published via platformSettings:

\n
{\n  \"platformSettings\": {\n    \"instagram\": {\n      \"videoType\": \"REELS\"\n    }\n  }\n}\n
\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
SettingValuesDefaultDescription
videoType\"REELS\", \"STORIES\"\"REELS\"Determines how videos are published
\n

Note: platformSettings is accepted by the MCP create_post and update_post tools as well as over REST. The schema is strict: a mistyped platform or key is rejected with a validation error rather than silently dropped.

\n

Examples

\n

Single Image Post

\n
Post this to Instagram:\n\"Morning coffee and code. Best way to start the day. #devlife #coding\"\n\n[Attach JPEG image]\n
\n

Formats: JPEG, PNG and WebP all work; WebP is converted before publishing.

\n

Carousel Post

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

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

\n

Reel

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

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

\n

Story

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

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

\n

Scheduled Post

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

Important Restrictions

\n
    \n

  1. Animated GIF, BMP and TIFF are rejected. JPEG, PNG and WebP are accepted, with WebP auto-converted.

    \n
    2. \n

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

    \n
    3. \n

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

    \n
    4. \n

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

    \n
    5. \n

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

    \n
    6. \n

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

    \n
    7. \n
\n

Best Practices

\n

Content

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

Timing
