Can Cursor post to social media?

Yes, once you connect an MCP server that can publish. PostWire is one: add it to Cursor with the config on this page and it gets five tools, including one that writes a native post per network and one that publishes.

Where does the MCP config live for Cursor?

This project only: .cursor/mcp.json; Every project: ~/.cursor/mcp.json

Do I need approval from TikTok or Meta first?

No. PostWire has already been through those reviews, so you publish through its approved apps. Telegram, Bluesky, Mastodon and Discord need no review from anyone.

Give Cursor the ability to post to social media

Cursor can publish to TikTok, Instagram, Facebook, YouTube, LinkedIn, X, Reddit, Telegram, Bluesky, Mastodon and Discord once you connect PostWire as an MCP server. Below is the exact config for Cursor — including the detail that makes a copied config fail silently.

Where the config goes

Scope	Path
This project only	`.cursor/mcp.json`
Every project	`~/.cursor/mcp.json`

Create the file yourself, then open Cursor Settings → Tools & MCP to enable it.

The config

{
  "mcpServers": {
    "postwire": {
      "command": "npx",
      "args": [
        "-y",
        "postwire-mcp"
      ],
      "env": {
        "POSTWIRE_API_KEY": "pw_live_your_key"
      }
    }
  }
}

The mistake that makes this fail silently

Project scope and global scope are different files. Putting the server in .cursor/mcp.json and then wondering why it is missing in another repo is the usual confusion — that path only applies to the repo it sits in.

Check it worked

Cursor Settings → Tools & MCP — postwire should be listed, and expanding it shows the five tools.

What it can do once connected

Tool	What it does
`generate_posts`	One prompt in, a native draft per network out — respecting each one's character limit, hashtag rules and link conventions.
`post_to_social`	Publish to one or many networks in a single call.
`get_post_status`	Check what happened to a post after it was accepted.
`list_platforms`	Which networks are available and which need approval.
`my_account`	Plan, usage and which brands are connected.

A prompt like "write a launch post for our new feature and publish it to TikTok, LinkedIn and Bluesky" becomes two tool calls: one to draft a native version per network, one to publish.

Networks differ more than people expect — X caps at 280 characters against YouTube's 5,000, Reddit has no hashtags, and TikTok, YouTube and Instagram all refuse text-only posts. See what breaks between any two networks.
