# Threads Post

Create and schedule posts on Meta's Threads using the Publora MCP server. Supports auto-threading for long content, image carousels (2-10 images), and reply control settings.

## Prerequisites

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

### Getting Started

1. **Create account** at [publora.com/register](https://publora.com/register) (free)
2. **Connect Threads** via Instagram OAuth in [Publora Dashboard](https://publora.com/dashboard)
3. **Get API key** at [publora.com/settings/api](https://publora.com/settings/api)
4. **Configure MCP** in Claude Desktop (`~/.claude/claude_desktop_config.json`):

```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

```bash
# 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": ["threads-12345"],
    "content": "Your post content",
    "scheduledTime": "2026-03-25T10:00:00Z"
  }'
```

**Platform ID Format:** `threads-{id}` (from `/platform-connections`)

📖 **Docs:** [docs.publora.com](https://docs.publora.com)

## Available Tools

### create_post
Create a new Threads post or thread.

**Parameters:**
- `platforms`: Array with your Threads connection ID (e.g., `["threads-12345"]`)
- `content`: Post text (auto-threads if over 500 chars)
- `scheduledTime`: ISO 8601 datetime (**required** - for immediate posting, use current time + 1 minute)

### get_upload_url
Get a presigned URL to upload images.

### list_posts / update_post / delete_post
Manage your scheduled and draft posts.

## Auto-Threading

When content exceeds 500 characters, Publora automatically creates a connected thread:

1. **Smart splitting**: Content is split at paragraph breaks (`\n\n`), then sentence boundaries (`. `, `! `, `? `), then word boundaries
2. **Auto-numbering**: Each part gets `(1/N)`, `(2/N)`, etc. at the end
3. **Reply chain**: Posts are connected using Threads' `reply_to_id` parameter

### Manual Thread Breaks

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

```
This is my first post in the thread.

---

This is my second post in the thread.

---

And this is my third post!
```

Or use explicit markers `[1/3]`, `[2/3]`, `[3/3]` (square brackets are preserved as written).

## Reply Control

Control who can reply to your posts via REST API `platformSettings`:

| Value | Description |
|-------|-------------|
| `""` (empty) | Default platform behavior (anyone can reply) |
| `"everyone"` | Explicitly allow anyone to reply |
| `"accounts_you_follow"` | Only accounts you follow can reply |
| `"mentioned_only"` | Only mentioned accounts can reply |

Note: `platformSettings` is not available via MCP - use REST API for reply control.

## Important Restrictions

1. **Single hashtag limit**: Threads allows maximum 1 hashtag per post. Additional hashtags are ignored by the platform.

2. **No post editing**: Once posted, Threads posts cannot be edited via API. Delete and repost if needed.

3. **Video carousels not supported**: Publora's carousel implementation supports images only. Standalone video posts work normally.

4. **Multi-threaded posts temporarily unavailable**: Content splitting into multiple connected replies is temporarily disabled. Single posts and carousels continue to work.

## Examples

### Simple Text Post
```
Post this to Threads:
"Just discovered an amazing productivity hack that saved me 2 hours today. The key is batching similar tasks together."
```

### Image Carousel
```
Create a Threads carousel with these 5 product evolution screenshots.
Caption: "From concept to launch - our 6-month journey. #buildinpublic"
```
Note: Requires 2-10 images. Videos in carousels are not supported.

### Long-Form Thread
```
Create a Threads thread from this content:
"Thread: 7 mistakes I made as a first-time founder

---

1. Hiring too fast. We went from 2 to 15 in 3 months. The culture suffered.

---

2. Ignoring unit economics. Revenue felt great until we calculated CAC..."
```

### Scheduled Post
```
Schedule this for tomorrow at 10 AM:
"Monday motivation: The best time to start was yesterday. The second best time is now."
```

## Best Practices

1. **Hook first**: First 2 lines determine engagement - make them count
2. **Optimal length**: 100-250 characters for single posts perform well
3. **Native content**: Original, conversational posts are rewarded
4. **Single hashtag**: Use one highly relevant hashtag (platform limit)
5. **No edit option**: Double-check content before posting

### Timing
- **Best times**: 7-9 AM, 12-1 PM, 7-9 PM in target timezone
- **Frequency**: 1-3 posts per day for growth
- **Consistency**: Regular posting signals active account

### Engagement
- Reply to comments within first hour
- Cross-reference your Instagram (accounts are linked)
- Use relevant topics/keywords for discovery

## Troubleshooting

| Error | Cause | Solution |
|-------|-------|----------|
| "Account not connected" | Threads/Instagram OAuth expired | Reconnect via Publora dashboard |
| "Content too long" | Post exceeds 500 chars and threading failed | Manually add `---` breaks |
| "Media upload failed" | Wrong format or size | Check: images < 8 MB, JPEG/PNG only |
| "Carousel requires 2-10 items" | Wrong number of images | Ensure 2-10 images for carousel |
| 250 posts/day exceeded | Rate limit reached | Wait 24 hours |
