Which ChatGPT plans can add Shapeless?

Plus, Pro, Business, Enterprise and Edu. Developer mode is what lets a personal account add its own plugin; a workspace admin can switch it off.

Do I need a X developer app or API key?

No. You connect your X account to Shapeless once, under Accounts, through X's own sign-in. Shapeless holds that connection; ChatGPT never sees a X token, and you never paste a key into ChatGPT either - it signs in to Shapeless with OAuth.

Will ChatGPT post to X without asking me?

Not unless you set a standing agent to auto-publish. A job proposes drafts and waits for your approval in Shapeless or in the chat; the tools that approve, publish or spend are flagged, so ChatGPT asks you before running one.

Can it make the X media, not just the words?

Yes - that is the point. We publish text, images and video here; PDF documents we do not deliver to X yet. X takes one video up to 2 min 20 s. You brief it in the chat; Shapeless designs the images or renders the narrated video with your actor and captions, and hands the draft back for approval.

What does X allow in a post?

280 characters and 4 images, 1 video up to 2 min 20 s, per X's own documentation as we last read it on 2026-07-21. Shapeless enforces the same table its publishing engine does, so a draft that breaks a limit is fixed before it is queued.

How do I disconnect it?

Settings → API keys → Connected apps in Shapeless lists ChatGPT with a Disconnect button; revoking there ends its access at once. ChatGPT also lets you remove the connector on its side.

Connect X to Shapeless, once

In Shapeless, open Accounts and connect your X account through X's own sign-in. Shapeless keeps that connection; ChatGPT never sees a password or token for it.

Ask ChatGPT in plain words

In a new chat, type @Shapeless or pick Shapeless from the + menu. Then ask in plain words. Every draft lands in your Shapeless queue for approval unless you say otherwise, and you are asked before anything goes out.

Draft a thread on X about why we rebuilt onboarding, six posts, with the demo GIF on the first.
Post this to X now: [paste]. Keep it under 280 characters and add the screenshot.
Queue three X posts for the launch tomorrow: 8am, noon, 5pm.

X allows 280 characters per post and 4 images, 1 video up to 2 min 20 s, from X's own documentation as read on 2026-07-21. Shapeless enforces that table before a draft is queued. The full table is on the X spec page; check a draft yourself with the free X character counter.

Post to X from Claude · X MCP server, for developers

For developers and agents: the MCP server, the tools, the CLI

Remote MCP server URL

https://shapelessai.com/mcp

A remote MCP server over streamable HTTP. Sign-in is OAuth 2.1 with dynamic client registration and PKCE, so any host - ChatGPT or your own agent - registers itself and opens a Shapeless tab to sign in and allow; the resource metadata is at /.well-known/oauth-protected-resource. Read tools run freely; anything that publishes, spends or overwrites is flagged destructive so the host asks first. The token is revocable under Settings → API keys → Connected apps.

Tool	What it does	Runs
me	Who this credential belongs to: email, plan, credit balance.	reads
connections_list	Connected social accounts (identity only, no tokens).	reads
jobs_create	Start a durable job from a goal, optionally with files attached. The run keeps going server-side; returns the job id and its web url to poll or continue.	drafts
jobs_list	List jobs with liveness and the web url of each, 200 per page, newest first. A non-null nextCursor means older jobs exist: pass it back as `before`.	reads
jobs_get	One job in full: transcript, running/idle status, outputs (posts with queue state, media) and its web url. Use jobs_brief when you only need enough to reply.	reads
jobs_brief	Compact context for continuing a conversation: the last messages clipped, an artifact inventory, post statuses, and the web url. Use jobs_get for the full transcript, jobs_continue to reply.	reads
jobs_tail	Watch a job's run: replays its events from the cursor, then follows live until the run ends, 60 seconds pass, or 200 events. Returns {live, cursor, events} - resume with that cursor. {live: false} means no run stream to attach to; the job may still have finished work, so read jobs_get.	reads
jobs_continue	Send another message to a job, optionally with files attached - also the way to resume a stuck or failed run with full history.	drafts
jobs_stop	Stop a running job.	asks you first
posts_list	The post queue: proposed drafts, scheduled posts, published history.	reads
posts_get	One post's live state.	reads
posts_approve	PUBLISHES CONTENT: approving moves proposals to the schedule, and they will go out.	asks you first
posts_dismiss	Dismiss proposed posts - nothing goes out.	asks you first
posts_publish	PUBLISHES CONTENT NOW: pushes a queued post to the platform immediately.	asks you first
characters_list	The account's actors: who they are, what their voice is, and which parts are locked. `voiceDescription` is the casting direction a designed voice was written from - read it before designing another one, and reuse the actor that already fits.	reads
characters_voice	SPENDS CREDIT: gives an actor a voice. `description` designs one from casting direction (kept on the character, so later runs can reuse the actor); `sampleMediaKey` clones a real voice and requires `consent: true` - the user's own attestation that they hold the rights. Returns the voice id, a preview clip and what it cost.	asks you first
brain_tree	Brand Memory's file list with the completion ring.	reads
brain_read	Read one Brand Memory file.	reads
brain_write	Write one Brand Memory file (.md paths only) - the agent grounds future posts in it.	asks you first
assets_list	The media library: brand uploads and generated media.	reads
agents_list	The agent roster (the API calls them strategies).	reads
agents_save	Create an agent (no id) or edit one (with id). Setting autoPublishPosts arms publishing without human approval and needs the publish scope; everything else needs write.	asks you first
agents_wake	PUBLISH-SCOPED: wake an agent now; it plans and proposes (or with auto-publish, posts) immediately. Returns the conversation it woke into and its web url.	asks you first

The same account is driveable from a terminal or a script with a scoped API key: npx shapelessai --help, or the REST API documented in the public agent repo. Keys are minted under Settings → API keys.
