Linkedin Post

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

Getting Started

1. Create account at publora.com/register (free)
2. Connect LinkedIn via OAuth in Publora Dashboard
3. Get API key at app.publora.com/dashboard/api
4. Connect your agent to the MCP server at https://mcp.publora.com, authenticating with Authorization: Bearer sk_YOUR_API_KEY. In Claude Code:

claude mcp add publora --transport http https://mcp.publora.com \
  --header "Authorization: Bearer sk_YOUR_API_KEY"

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.

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

Platform Limits

Available Tools

create_post

Create a new LinkedIn post or schedule for later.

Parameters:

• platforms: Array including your LinkedIn connection ID (e.g., ["linkedin-abc123"])
• content: Post text (up to 3,000 characters)
• scheduledTime: ISO 8601 UTC datetime. Optional: omit it and the post is created as a draft. Send a future time to schedule. A time five or more minutes in the past is rejected with SCHEDULED_TIME_IN_PAST, so for immediate posting use the current time plus a minute.
• mediaUrls: up to 10 public https image or video URLs. Publora downloads them server-side and attaches them before validation, so media and scheduling happen in one call. This is the one-shot alternative to the draft then get_upload_url then complete_media flow. Ingestion is rate-limited to 60 URLs per hour.

get_upload_url

Get a presigned URL to upload media.

Parameters:

• postGroupId: The post ID to attach media to
• fileName: File name (e.g., "chart.png")
• contentType: MIME type (e.g., "image/jpeg", "video/mp4", "application/pdf")
• type: "image" or "video"

complete_media

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.

Parameters:

• mediaId: the id returned by get_upload_url

list_connections

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

list_posts / get_post / update_post / delete_post

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.

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.

Do not hand-write member ids. The linkedin_list_mentionables MCP tool resolves a name to the correct URN; see the linkedin-analytics skill.

Important API Restrictions

1. No organic carousels: Swipeable multi-image carousels are NOT available via API (only for sponsored content). Multi-image posts appear as a grid layout.

2. No mixed media: Cannot combine images with videos or documents in the same post.

3. No rich text: LinkedIn API does not support bold, italic, or other formatting. Use plain text or Unicode characters for emphasis.

4. 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

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