Boring Threads Publisher

Publish posts, multi-post threads, and replies on Threads. Powered by Boring.

Security & Data Handling

• MCP link is a credential: Your MCP Server URL contains an embedded authentication token. Treat it like a password — do not share it publicly. Regenerate anytime in Settings.
• Media uploads: Local files or URLs are uploaded to Boring's Google Cloud Storage to make them accessible for publishing. Social media APIs require publicly accessible media URLs.
• Data flow: Your content and media are sent from Boring's server to Threads' API on your behalf via your connected OAuth token.
• No local credentials: No local API keys or environment variables needed. All auth is embedded in the MCP link.

Prerequisites

1. Sign up at boring.aiagent-me.com with Google
2. Connect Threads account via OAuth
3. Get your MCP link: Go to Settings → copy your MCP Server URL (contains your auth token — treat it like a password)
4. Add to Claude: Paste the MCP link as a Connector — no install, no API key needed

Workflow

Step 1: List Accounts

Call boring_list_accounts and filter for threads platform. Show connected accounts.

Step 2: Determine Post Type

Threads supports multiple content types:

Step 3: Choose the Right Tool

Single post (text, photo, carousel, video) → use boring_publish_post:

boring_publish_post(
  account_id="\x3Cthreads_account_id>",
  platform="threads",
  text="Your post content",
  media_urls=["https://..."]  (optional)
)

Multi-post thread (long-form content split into connected posts) → use boring_publish_thread:

boring_publish_thread(
  account_id="\x3Cthreads_account_id>",
  platform="threads",
  texts=["First post in thread", "Second post continues...", "Third post wraps up"],
  media_urls=["https://..."]  (optional, added to first post only)
)

Reply to existing post → use boring_reply_to_post_threads:

boring_reply_to_post_threads(
  account_id="\x3Cthreads_account_id>",
  reply_to_id="\x3Coriginal_post_id>",
  text="Your reply here",
  media_urls=["https://..."]  (optional, first URL only)
)

Step 4: Handle Long Content

If the user provides content longer than 500 characters:

1. Automatically split into multiple posts for a thread
2. Split at sentence boundaries when possible
3. Use boring_publish_thread with the array of texts
4. Inform the user: "Your content was split into X connected posts"

Step 5: Prepare Media

• Local files: boring_upload_file with file_path
• URLs: boring_upload_from_url to re-host
• Google Drive: Pass directly

Step 6: Publish and Report

Show results:

• Post ID(s) for each published post
• Thread URL if it was a multi-post thread
• Any errors encountered

Scheduling

Add scheduled_at in ISO 8601 format to schedule:

boring_publish_post(..., scheduled_at="2025-12-25T10:00:00Z")
boring_publish_thread(..., scheduled_at="2025-12-25T10:00:00Z")
