How to create social media carousels from inside Claude

You are already writing in Claude. You describe the post you want, Claude writes something good, and then you leave the conversation, open a design tool, rebuild the idea slide by slide, apply your brand, export, and go schedule it somewhere else.

That handoff is the whole problem. Zynta Flow runs a remote MCP server, so you can skip it: ask for the carousel in the conversation and it appears in your Zynta Flow account, on brand, ready to schedule.

Here is how to set it up, what it can actually do, and where the edges are.

What MCP is, briefly

MCP (Model Context Protocol) is an open standard for letting an AI assistant use an outside tool. Anthropic published it in November 2024 and it is now supported by Claude, ChatGPT, Cursor, and a long list of others.

A "remote MCP server" is a URL. You give it to your assistant, sign in once, and from then on the assistant can call that product's features directly. Nothing is installed, nothing runs on your laptop.

Zynta Flow's server lives at:

https://zyntaflow.com/api/mcp

Connecting it to Claude

1. Open Settings, then Connectors.
2. Click +, then Add custom connector.
3. Paste https://zyntaflow.com/api/mcp and confirm.
4. Claude checks the URL and fills in the authentication settings on its own. You do not need to create an API key, paste a client ID, or fill in a secret.
5. Click Connect. A Zynta Flow sign-in opens. Sign in, approve access, and you are done.

That step 4 is worth a sentence. Zynta Flow implements OAuth 2.1 with PKCE and Dynamic Client Registration, which is the part of the spec that lets a client register itself. It is why the setup is a paste and a sign-in rather than a support ticket.

Two things to know:

• Custom connectors work on Claude, Claude Desktop and Cowork, on free and paid plans. Free accounts are limited to one custom connector, so if you already have one you will need to choose.
• Claude connects to the server from Anthropic's cloud, not from your computer. That is fine here, since Zynta Flow is on the public internet, but it is the reason a server running on your own machine would not work.

To change a connector later, remove it and add it again. There is no edit.

What you can ask for

Once it is connected, this is the kind of thing that works:

Make me a 6 slide carousel about why most agency content approvals take three days, in the Zuur brand kit, and schedule it for Tuesday at 6pm.

Claude will generate the copy slide by slide, apply the brand kit you named, build the slides, write the caption, and create the calendar entry. You get a link back and can open it in the editor if you want to change anything.

The full set of things it can do:

• Create: generate a carousel from a brief, create a single image post, adjust a slide's layout, attach your own image or pull one from Unsplash.
• Write: set the caption for a post, in the brand voice.
• Brand: read, create, and update brand kits, and list the ones you have.
• Schedule: create, update and read calendar entries, so a post can be planned for a specific date and time.
• Read: list your drafts and presets, see which social accounts are connected, and pull post analytics.

The one thing it deliberately does not do is publish on its own. Scheduling is a calendar entry you can see and change before it goes out. An assistant that can post to your audience without a human step is a bad idea, and we did not build it.

What it costs

MCP is on every plan, including the free trial. It is not a tier perk.

Actions spend credits from the same balance at the same rate as the web app: a carousel with AI copy is 20 to 45 credits depending on slide count, a caption is 10, publishing is 5 per post per network. Reading your brands, drafts, and analytics is free.

If the balance runs out, the assistant gets an "insufficient credits" answer, exactly like you would in the app. There is no way for an agent to spend money you have not already put in the account.

Where this actually helps

Honestly, not everywhere. If you make one carousel a month, opening the app is fine.

It earns its place when you run several brands. The pattern that changed how I work is asking for the same brief across different brand kits in one message, and getting back a set of posts that each look like they belong to their own company. Doing that by hand is the afternoon you were dreading.

It also helps when the idea arrives mid conversation. You are talking through positioning with Claude, something good comes out of it, and instead of writing it down to handle later, you say "make that a carousel for Thursday" and it is handled.

If something goes wrong

The connector fails to add. Check you pasted the full URL including /api/mcp. The bare domain is the marketing site, not the server.

Sign-in works but nothing happens. Remove the connector and add it again. Claude has no edit, and a half-configured connector stays half-configured.

A tool call comes back with insufficient credits. That is the balance, not the connection. Top up or wait for the monthly grant.

You want to use a client that cannot do OAuth. Create a personal access token in Zynta Flow under Settings, Security, and send it as a bearer token. That path exists for automation, which has no browser to open a consent screen in.

Try it

Zynta Flow is free to start, 200 credits for 14 days, no credit card. Connect the server, ask for a carousel, and see whether the output is something you would actually post.
