Automate Threads with OpenClaw
Threads carries twice as much media in a single post as anything else here, on one of the tightest text limits.
$ mcporter config add antwork --url https://api.antwork.io/mcp --auth oauthOpenClaw connects to Antwork over MCP with a browser OAuth prompt. There is no API key to generate, copy, or paste into a URL.
Connect it
- 01Approve in the browserThe command opens an OAuth consent screen. Approve it and the connection is live — the token refreshes itself, so publishing does not silently break weeks later.
- 02Connect the social accountAsk OpenClaw to connect your account and it renders a panel with a button per platform. Authorize once and Antwork holds and refreshes that token for you.
- 03Add the skill (optional)clawhub install iker-gonzalez/antwork teaches the agent the right tool order — pull context, draft, then schedule or publish as a second explicit step.
What you can say once Threads is connected
“Draft a Threads post introducing this set of screenshots, short, in my voice.”
“Take the Instagram caption I just approved and rework it for Threads.”
“Post this to Threads and schedule the same media for Instagram an hour later.”
“What did my last few Threads posts do?”
You see it before it goes out
Antwork does not answer with a wall of text. It renders real, clickable panels inside OpenClaw — the same interface you would get in a dashboard, in the conversation you are already in. No other social tool does this.
- 01A post card with the draft, editable in place, with the publish and schedule buttons on it
- 02A month calendar of everything scheduled across every connected account
- 03Your media library as a thumbnail grid you can attach from
- 04A connections panel with a Connect button per platform
- 05A table of recent posts you can click into
Shipped something small this week that fixed a big thing. Our token refresh ran daily but checked Threads against a five minute expiry window, so it could only ever catch a token that happened to die inside those five minutes. It never did. Accounts just went quiet.
What is different about Threads
Only hereTwenty items in one post
Twenty images or videos, mixed however you like. Nothing else Antwork posts to comes close; the next highest stops at ten, and most stop at one.
The text is the caption, not the post
Five hundred characters is the second tightest limit here. The agent drafts to it instead of writing long and trimming, because on Threads the media carries the post and the text introduces it.
The largest payload Antwork will build
Each video can run five minutes at 1 GB, and there can be twenty of them. No other post this platform builds can be that big.
The same shapes Instagram takes
Video ratios are 9:16, 1:1 and 4:5, matching Instagram exactly. A cut made for one reposts to the other without recutting, which is the usual reason to run them as a pair.
Questions
- Do I need an API key to connect OpenClaw?
- No. Antwork connects over OAuth — you approve a consent screen in the browser and you are done. There is no key to generate or paste into a URL, which is how most social MCP servers handle it.
- Do I need a paid account?
- No. Your first two connected accounts are free forever, with unlimited posts and workspaces, and there is no plan gate on MCP access.
- Will OpenClaw post without showing me first?
- Not unless you ask it to. Drafting and publishing are two separate steps: the agent writes, renders the post card, and only publishes when you confirm.
- Does the writing sound like AI?
- Antwork hands the agent that account's recent posts, along with how each performed, and the agent writes to match them. On Threads that includes writing to the length the format rewards, up to 500 characters.
Never leave OpenClaw to post again.
One command, one consent screen, and Threads is something you can just ask for.
