LinkedIn Post

Create and schedule LinkedIn posts using the Publora MCP server. Supports text posts, single images, multi-image posts (grid layout), videos, and PDF documents.

Prerequisites

Plans: Starter (free), Pro, Premium - LinkedIn is available on all plans including free.

Getting Started

Create account at publora.com/register (free)
Connect LinkedIn via OAuth in Publora Dashboard
Get API key at publora.com/settings/api
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": ["linkedin-Tz9W5i6ZYG"],
    "content": "Your post content here",
    "scheduledTime": "2026-03-25T10:00:00Z"
  }'

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

Example IDs: linkedin-Tz9W5i6ZYG, linkedin-abc123xyz

Mentioning People and Companies

LinkedIn posts support @mentions using URN syntax:

@{urn:li:person:MEMBER_ID|Display Name}       # Mention a person
@{urn:li:organization:ORG_ID|Company Name}    # Mention a company

Example:

Great insights from @{urn:li:person:4986615|Serge Bulaev} at @{urn:li:organization:107107343|Creative Content Crafts Inc}!

Important: The display name must exactly match the LinkedIn profile name (case-sensitive), including company suffixes like "Inc", "LLC", etc.

Important API Restrictions

No organic carousels: Swipeable multi-image carousels are NOT available via API (only for sponsored content). Multi-image posts appear as a grid layout.
No mixed media: Cannot combine images with videos or documents in the same post.
No rich text: LinkedIn API does not support bold, italic, or other formatting. Use plain text or Unicode characters for emphasis.
PDF alternative for carousels: To share multi-page swipeable content, upload a PDF document instead.

Examples

Simple Text Post

Schedule a LinkedIn post for tomorrow at 9 AM:
"We're thrilled to announce the release of our AI writing assistant. After 18 months of development, we're ready to help teams write better content faster."

Post with Mention

Create a LinkedIn post mentioning our CEO:
"Excited to share insights from @{urn:li:person:4986615|Serge Bulaev} on the future of AI in content creation."

Multi-Image Post

Create a LinkedIn post with 4 product screenshots showing our new dashboard features.

Note: Images will appear in a grid layout, not as a swipeable carousel.

PDF Document Post

Share our Q4 report as a PDF on LinkedIn with a summary caption.

This is the best way to share multi-page carousel-like content.

Best Practices

First line matters: First 210 characters appear before "see more" - make them compelling
Optimal length: Posts under 1,300 characters tend to perform better
Posting times: Tuesday-Thursday, 8-10 AM in your audience's timezone
Hashtags: Use 3-5 relevant hashtags - they're supported as plain text
Engagement: End with a question to encourage comments

Troubleshooting

Error	Cause	Solution
"Account not connected"	LinkedIn OAuth expired	Reconnect in Publora dashboard
"MEDIA_ASSET_PROCESSING_FAILED"	File too large or wrong format	Check: images < 5 MB, videos < 500 MB MP4
"Rate limited" (429)	Too many API calls	Wait and retry with backoff
"Cannot mix media types"	Images + video in same post	Use only one media type per post
MCP unavailable	Server issue	Use REST API fallback (see above)
