X/Twitter Post

Create and schedule posts to X (Twitter) using the Publora MCP server. Supports text posts, images (up to 4), videos, and automatic thread splitting for long-form content.

Prerequisites

Plans: Pro ($2.99/account/month), Premium ($9.99/account/month)

Important: X/Twitter is NOT available on the free Starter plan due to Twitter API costs.

Getting Started

1. Create account at publora.com/register
2. Choose Pro or Premium plan (X/Twitter requires paid plan)
3. Connect X/Twitter 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 MCP is unavailable, use the REST API directly:

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

Authentication: x-publora-key header

# Get 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": ["twitter-123456789"],
    "content": "Your tweet content",
    "scheduledTime": "2026-03-25T10:00:00Z"
  }'

Platform ID Format: twitter-{id} (e.g., twitter-123456789)

Character Counting

X has specific character counting rules that Publora handles automatically:

• Standard characters = 1
• Emojis = 2 characters
• URLs counted by literal length
• Thread markers reserve 10 characters per tweet

Auto-Threading

When content exceeds 280 characters, Publora automatically creates a connected thread:

1. Content split at paragraph breaks, then sentence boundaries, then word boundaries
2. Each part numbered with (1/N), (2/N) format
3. Tweets connected via X's reply_to_id parameter

Manual Thread Breaks

Use --- on its own line to force a thread break:

This is my first tweet in the thread.

---

This is my second tweet in the thread.

---

And this is my third tweet!

Available Tools

Examples

Simple Tweet

Post this to X:
"Just shipped our new API documentation. Check it out!"

Tweet with Images

Post this to Twitter with screenshots of the new dashboard:
"Before and after our redesign. What do you think?"

Note: Up to 4 images allowed. All images auto-converted to PNG.

Long-Form Thread

Create a Twitter thread:
"Thread: 5 lessons from building our startup

---

1. Ship early, iterate fast. We launched with a buggy MVP and improved based on real feedback.

---

2. Talk to users daily. Our best features came from customer conversations.

---

3. Focus beats features. We killed 3 products to focus on the one that worked."

Scheduled Tweet

Schedule this for tomorrow at 9 AM:
"Monday motivation: Start before you're ready."

Important Restrictions

1. Pro plan required: X/Twitter is excluded from the free Starter plan due to Twitter API costs.

2. 2-minute video limit: The X API limits videos to 2 minutes, even though the native app allows longer videos.

3. Image auto-conversion: All images are converted to PNG (max 1000px width) before upload. Animated GIFs lose animation.

4. No image+video mix: A tweet can have images OR video, not both.

5. Media on first tweet only: In threads, images/video attach to the first tweet only.

Best Practices

Content

1. Hook in first line: Most engagement happens on the first tweet
2. Optimal thread length: 3-7 tweets for best engagement
3. Emoji awareness: Remember emojis count as 2 characters

Timing

• Best times: 8-10 AM, 12-1 PM, 5-6 PM in target timezone
• Frequency: 3-5 tweets per day for growth
• Threads: Post in morning for maximum visibility

Engagement

• Reply to comments within the first hour
• Quote tweet your own threads for visibility
• Use relevant hashtags (1-2 per tweet)
