Connect Cursor to PosteAhora, step by step
Seven steps, about three minutes, in the Cursor desktop app. Menu names are Cursor's English ones.
Before you start
You need a PosteAhora account with at least one network connected, and Cursor installed. Nothing to install from us: the server runs on our side.
The connector URL is the same for every client: https://mcp.posteahora.com/mcp. It signs you in with your PosteAhora account — no API key to paste. Networks are connected in Connections first; the assistant can only reach what is connected there.
1. Click Add to Cursor
Use the Add to Cursor button on the PosteAhora page. It opens Cursor's install page, which hands off to the app with our server already filled in — name posteahora, URL below.
https://mcp.posteahora.com/mcp
Rather do it by hand? Add the server under mcpServers in ~/.cursor/mcp.json (every project) or .cursor/mcp.json (this project only), with the URL above and no headers.
2. Confirm the install
Cursor shows the server it is about to add. Check the URL is mcp.posteahora.com and install it.
3. Sign in with PosteAhora
Cursor sees that the server needs a sign-in and opens a PosteAhora page in your browser. Sign in there if you are not already.
Nothing to paste: no client ID, secret or API key. Cursor registers itself with our server.
4. Pick a workspace and approve
The page shows who you are signed in as and what Cursor will be able to do — read and manage your posts, ideas, connected accounts and analytics. Choose the workspace and click Approve, then go back to Cursor.
The connection is fixed to that workspace. To work in another one, sign in again and pick it there.
5. Check it is on
Open Customize from Cursor's sidebar: PosteAhora is listed among your MCP servers with its tools. Switch it on if it is off.
6. Ask in Agent chat
Describe the post and when it should go out. Cursor asks you to approve each PosteAhora tool call first — open it to see the arguments.
Write a LinkedIn post about what changed in this release and schedule it for Tuesday at 9:00.
7. See it in your queue
Open Publish in PosteAhora: the post sits under Tuesday at 9:00, marked scheduled, editable until it goes out.
Where these steps come from
Not yet run by us. These steps follow Cursor's MCP documentation — install links, mcp.json and OAuth for remote servers — and were written on September 26, 2026. The URL, the OAuth sign-in and the workspace approval are ours; the Cursor screens have not been run end to end by us yet, which is why there are no screenshots. When a menu name no longer matches, trust Cursor's docs, and tell us. Source: Cursor MCP docs.
FAQ
Can Cursor post to social media on its own?
No. Cursor's agent can read your code and run commands, but it has no publishing rights on any social network. PosteAhora is the MCP server that gives it those: you connect Instagram, X, LinkedIn and the rest in PosteAhora once, and the agent publishes through those connections. It never sees the networks' passwords, only the tools we expose.
How do I add PosteAhora to Cursor?
Click Add to Cursor on this page: Cursor opens an install dialog already filled in with our server, and you confirm it. Or add it by hand — put https://mcp.posteahora.com/mcp under mcpServers in ~/.cursor/mcp.json for every project, or in .cursor/mcp.json for one. Either way Cursor then asks you to sign in.
Do I need an API key?
No. Cursor signs you in with OAuth in the browser and you pick the workspace it may use. An API key is only for setups without a browser — a CI job, say — where you send it as an Authorization: Bearer header from mcp.json, or for running our npm package locally.
Does it work in the Cursor CLI?
Yes. The CLI reads the same mcp.json as the editor. Run agent mcp login posteahora once to sign in, check the tools with agent mcp list-tools posteahora, and schedule with agent -p "…".
Will Cursor publish something I did not approve?
By default Cursor asks you to approve every MCP tool call before it runs, and you can see its arguments first. And a scheduled post waits in your PosteAhora queue, where you can edit or delete it before it goes out — nothing leaves early unless you ask it to publish now.
Can it attach a screenshot from my repo?
Yes. The server runs on our side and can't read your disk, so the agent asks it for an upload link and sends the file there itself — the same way it runs any other command. A public URL works too.
Which workspace does Cursor post to?
The one you approve when you sign in. The connection is fixed to it; to post from another workspace, sign in again and pick that one.
What does it cost?
Cursor is billed by Cursor. On our side there is a 7-day trial for $0 with a card on file, then a flat monthly or yearly price by plan, with the MCP server included. Every plan has unlimited posts; what varies is how many social accounts you can connect.
