Which Claude plans can add Shapeless?

Free (one custom connector), Pro, Max, Team and Enterprise. On Team and Enterprise an owner adds it under Organization settings and everyone connects their own account.

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; Claude never sees a X token, and you never paste a key into Claude either - it signs in to Shapeless with OAuth.

Will Claude 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 Claude 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 Claude with a Disconnect button; revoking there ends its access at once. Claude also lets you remove the connector on its side.

Ask Claude in plain words

In a chat, open the + menu under the composer, choose Connectors and check that Shapeless is switched on. 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 ChatGPT · 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 - Claude 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.
