name: threads-post\ndescription: Create and schedule Threads posts with image carousels and reply control via Publora MCP. Use when the user wants to post to Meta's Threads. Multi-part threading is currently disabled by the platform, so long content stays a single post. Not for Instagram (use instagram-post) or X threads (use x-post).

\n

Threads Post

\n

Create and schedule posts on Meta's Threads using the Publora MCP server. Supports single posts, image carousels (2-20 images) and reply control. Multi-part threading is disabled by the platform connection right now.

\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. Connect Threads via Instagram OAuth in Publora Dashboard
    3. \n
  3. Get API key at app.publora.com/dashboard/api
    4. \n
  4. Connect your agent to the MCP server at https://mcp.publora.com, authenticating with Authorization: Bearer sk_YOUR_API_KEY. In Claude Code:
    5. \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 MCP is unavailable, use the REST API directly:

\n

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

\n

Authentication: x-publora-key header

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

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

Available Tools

\n

create_post

\n

Create a new Threads post or thread.

\n

Parameters:

\n\n

get_upload_url

\n

Get a presigned URL to upload images.

\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

Long Content

\n

Threads posts are capped at 500 characters and Publora's multi-part threading is currently disabled while the Threads app connection is being restored. Content over the limit is not split automatically, so:

\n\n

Manual --- separators and [1/3] markers are preserved as written but do not create a connected reply chain right now. Contact support@publora.com for the restore timeline.

\n

Reply Control

\n

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

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
ValueDescription
\"\" (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
\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

Important Restrictions

\n
    \n

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

    \n
    2. \n

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

    \n
    3. \n

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

    \n
    4. \n

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

    \n
    5. \n
\n

Examples

\n

Simple Text Post

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

Image Carousel

\n
Create a Threads carousel with these 5 product evolution screenshots.\nCaption: \"From concept to launch - our 6-month journey. #buildinpublic\"\n
\n

Note: Requires 2-20 images. Videos in carousels are not supported.

\n

Long Content (published as separate posts)

\n

Threading is disabled, so ask for the parts explicitly:

\n
Post this to Threads as separate posts:\n\"Thread: 7 mistakes I made as a first-time founder\n\n---\n\n1. Hiring too fast. We went from 2 to 15 in 3 months. The culture suffered.\n\n---\n\n2. Ignoring unit economics. Revenue felt great until we calculated CAC...\"\n
\n

Scheduled Post

\n
Schedule this for tomorrow at 10 AM:\n\"Monday motivation: The best time to start was yesterday. The second best time is now.\"\n
\n

Best Practices

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