How do I set up Threads posting through this skill?

Create a free account at publora.com/register, connect Threads via Instagram OAuth in the Publora dashboard, generate an API key at publora.com/settings/api, then configure Claude Desktop's `claude_desktop_config.json` with an HTTP MCP server pointing to `https://mcp.publora.com` and an `Authorization: Bearer YOUR_API_KEY` header.

What are the content limits for Threads posts with this skill?

Threads posts are limited to 500 characters per post, 1 hashtag maximum, 5 links maximum, 2-10 images per carousel at up to 8MB each (JPEG/PNG), and 5-minute/500MB videos (MP4/MOV). Daily rate limits are 250 posts and 1,000 replies per day.

How does auto-threading work for long content?

Content over 500 characters automatically splits at paragraph breaks first, then sentence boundaries, then word boundaries. Each part is auto-numbered (1/N, 2/N, etc.) and connected via Threads' reply feature, or you can force manual breaks using `---` lines or explicit markers like `[1/3]`/`[2/3]`/`[3/3]`.

Can I control who can reply to my Threads posts through this skill?

Reply control settings (everyone, accounts you follow, or mentioned accounts only) are not available through the MCP interface and require using the REST API at `https://api.publora.com/api/v1` with the `platformSettings` field instead.

What's the difference between the MCP interface and the REST API?

The MCP interface handles post creation, scheduling, and management through Claude, while the REST API at `https://api.publora.com/api/v1` (authenticated with an `x-publora-key` header) covers the same operations plus reply control settings that MCP doesn't expose.

Overview

Threads Post via Publora

Creates and schedules Threads posts through Publora MCP: auto-threading for long content, 2-10 image carousels, and reply-control settings, within Threads' own platform limits. Use it when posting or scheduling long-form, carousel, or reply-restricted content specifically to Threads through Publora's MCP or REST interface.

What it does

Creates and schedules posts on Meta's Threads through the Publora MCP server: auto-threading for long content, image carousels of 2-10 images, and reply-control settings. Setup connects Threads via Instagram OAuth in the Publora dashboard, then an API key and the same MCP server entry - or REST fallback with an x-publora-key header - as other Publora platforms.

curl -X GET "https://api.publora.com/api/v1/platform-connections" \
  -H "x-publora-key: sk_your_api_key"

Threads' platform limits: 500 characters per post, a maximum of one hashtag (extras are ignored by the platform itself), up to 5 links, 2-10 images per carousel at up to 8 MB each in JPEG or PNG (WebP is auto-converted), video up to 5 minutes and 500 MB in MP4 or MOV, and daily caps of 250 posts and 1,000 replies. Content over 500 characters auto-threads: splitting first at paragraph breaks, then sentence boundaries, then word boundaries, numbering each part (1/N) and chaining them via Threads' reply_to_id; a manual --- on its own line forces a thread break, or explicit [1/3]-style markers can be used directly. Reply control - restricting replies to everyone, accounts you follow, or only mentioned accounts - is REST-API-only, not exposed through MCP. Threads posts cannot be edited once published, video carousels aren't supported (only image carousels), and multi-threaded posting - splitting one request into several connected replies - is temporarily disabled, though single posts and image carousels still work.

When to use - and when NOT to

Use it when posting or scheduling content to Threads specifically - long-form auto-threaded posts, image carousels, or reply-restricted posts - through Publora's MCP or REST interface.

Inputs and outputs

Input: post content (auto-threads past 500 characters), a Threads connection ID, and a required ISO 8601 scheduledTime. Output: a created or scheduled Threads post or thread, or a management action via list_posts/update_post/delete_post; reply-control settings require the REST API's platformSettings field.

Integrations

Runs through the Publora MCP server (or its REST API fallback) against Threads' API via Instagram OAuth, on Free Starter (15 posts/month), Pro ($2.99/account/month, 100/account), or Premium ($9.99/account/month, 500/account) plans.

Who it's for

Users scheduling long-form or carousel content to Threads, especially multi-part threads or reply-restricted posts, through an agent rather than the native Threads composer.

Its own best-practice guidance favors a strong hook in the first two lines, an optimal single-post length of 100-250 characters, and native conversational tone over polished copy, posted 1-3 times daily at 7-9 AM, 12-1 PM, or 7-9 PM in the target timezone.
