Connect Cursor

SimplePost is not in the Cursor Marketplace. You add the hosted server to Cursor's mcp.json yourself (or load the repository as a local Agent Plugin), and Cursor handles the OAuth sign-in.

What you need

Cursor with MCP support for remote Streamable HTTP servers.
A SimplePost account on the free trial or any paid plan, with social accounts connected in the web app.

Add SimplePost to mcp.json
Use .cursor/mcp.json in a project, or ~/.cursor/mcp.json for every project.
```
{
  "mcpServers": {
    "simplepost": {
      "url": "https://app.simplepost.social/mcp"
    }
  }
}
```
Sign in
Open Cursor's MCP settings, find simplepost and start the login. Approve access on the SimplePost page that opens.
Check the tools
The server should list its tools, including list_accounts, create_post and get_schedule.
Test with a draft
Ask the agent to list your SimplePost accounts and save a test draft, then look at it in the SimplePost web app.

Workflow

Example: publish a release from Cursor

Ask the agent in the repository you are shipping. Keep the review step: the agent saves a draft first.

1. Summarize the release

Read the latest section of CHANGELOG.md and the merged pull requests for this release. Write three user-facing highlights.

Result: The agent reads the repository and proposes highlights for you to correct.

2. Draft and preview

Using SimplePost, list my accounts, then save a draft with a LinkedIn post and an X thread built from those highlights. Show me each version.

Result: One draft with per-account versions is saved and each version is returned for review.

3. Schedule

Schedule the draft for tomorrow at 10:00 America/New_York.

Result: The post is scheduled with an exact timestamp; the agent reports the accounts and time.

Publishing details

What Cursor can do

Turn a changelog entry, pull request or diff into a user-facing announcement.
Create one post with different versions per network.
Save drafts, return previews and schedule posts for the release time.
List, edit or discard scheduled posts if a release moves.

Connect social accounts in the SimplePost web app. Engagement analytics and changes to already published posts stay on the social network.

Different versions for each network

Keep one post per announcement and let per-account overrides carry the differences between networks.
If the release includes screenshots, host them publicly (for example as release assets) and give the agent the URLs.

Sign-in and permissions

SimplePost supports OAuth dynamic client registration, so Cursor registers itself and no client ID or secret is needed in mcp.json.
Do not add an API key header: SimplePost's MCP server accepts only OAuth tokens, and API keys are for the Pro HTTP API.
Tokens expire after 90 days; sign in again from Cursor's MCP settings when prompted.

Publishing actions and tools

What Cursor can do at each stage
Preview	preview_post returns validation details and the resolved schedule; show_post_preview returns the preview result.
Schedule	create_post with a scheduled time and an idempotency key.
Publish now	create_post in now mode; results are reported per account.
View scheduled posts	get_schedule or inspect_posts with the scheduled filter.
Update or cancel	update_scheduled_post or discard_scheduled_post until the post starts publishing.

If something does not work

The server shows an authentication error

Start the login again from Cursor's MCP settings and approve access in the browser with the same SimplePost account.

The agent cannot find accounts

Social accounts are connected in the SimplePost web app, not through Cursor. Connect one, then ask again.

Local image paths fail

The hosted server cannot read your disk. Use public URLs or upload the media in the web composer.

Supported platforms

Networks Cursor can publish to

All ten hosted networks work the same way from Cursor: X, LinkedIn, Instagram, Facebook, Threads, Bluesky, TikTok, YouTube, Pinterest and Telegram. These platform guides are most relevant here:

FAQ

Cursor and SimplePost questions

Is SimplePost in the Cursor Marketplace?

Not currently. Add the hosted server to mcp.json manually, or load the SimplePost repository as a local Agent Plugin.

What goes in Cursor's mcp.json for SimplePost?

A server entry named simplepost with the url https://app.simplepost.social/mcp. No headers or keys are needed; Cursor completes OAuth when you sign in.

Can Cursor post to LinkedIn and X?

Yes, once those accounts are connected in SimplePost. The agent creates the post in SimplePost, which publishes it to each account.

Does the Cursor integration cost extra?

No. MCP is included on every SimplePost plan and the free trial.
