Connect Cursor to social media
Can Cursor post to social media? Yes. Add the Postprism MCP server to Cursor’s mcp.json and the Cursor agent can draft, schedule and check posts for 6 social networks. It is the quickest way to turn a release you just finished into launch posts without switching apps.
How to connect Cursor to Postprism
What you need
- Cursor with Agent mode
- Node.js 18 or later (the config runs the connector with npx)
- A Postprism account with at least one social account connected
- 01
Open MCP settings
In Cursor, open Settings > MCP and choose Add new global MCP server. This opens ~/.cursor/mcp.json. For one project only, create .cursor/mcp.json in the repo instead.
- 02
Add the Postprism server and save
Paste the postprism entry under mcpServers.
mcp.json{ "mcpServers": { "postprism": { "command": "npx", "args": [ "[email protected]", "https://studio.postprism.app/api/mcp" ] } } } - 03
Sign in
Cursor starts the server and a browser tab opens to sign in to Postprism. Approve access; the server shows a green dot in Settings > MCP.
- 04
Try it in Agent mode
Open the agent and ask “list my Postprism platforms”. Cursor asks to run list_platforms; approve it.
What it looks like
Look at the diff on this branch and draft an X post and a LinkedIn post announcing the new export feature. Save as drafts for Thursday 4 PM.
The agent reads the diff, writes both posts in plain language (no code jargon), and calls create_post. The draft appears on Thursday in your Postprism calendar.

In the walkthrough, the marketer writes one post herself, then asks Claude to plan the follow-ups. They land on the same calendar.

| delete_post | Delete a post by ID. |
| upload_media | Upload an image or video (JPEG, PNG, GIF, WebP, MP4, MOV, up to 10 MB) and get a URL to attach to a post. |
| get_analytics | List analytics records, filtered by post or platform. |
| get_post_analytics | Every analytics record for one post. |

Working well with Cursor
Add a rule
Put your social tone in a Cursor rule (.cursor/rules) so the agent writes posts the same way every time.
Keep approvals on
Leave tool approval on for Postprism, so you see every create_post call before it runs.
Limits to know
- The agent works inside your Postprism workspace. It can only post to social accounts you have already connected in Postprism; connecting a new account always happens in Postprism, through each network’s own sign-in.
- Each network’s own rules still apply: Pinterest Pins need an image, TikTok and YouTube need a video, X posts are capped at 280 characters, and Bluesky at 300.
- Media has to be uploaded with upload_media first (JPEG, PNG, GIF, WebP, MP4 or MOV, up to 10 MB per file). Links to files hosted elsewhere are rejected.
- A post created without a date is saved as a draft. A post created with scheduled_at is scheduled and publishes automatically, so ask for drafts if you want to review first.
- The MCP server allows 200 requests per hour per user, which is plenty for planning a month of posts but not for bulk-migrating thousands.
