Connect Claude to Socialync

Schedule and draft social media posts from Claude, ChatGPT, Cursor, or any AI assistant that supports the Model Context Protocol.

Read this first: what MCP can and can't do

We deliberately scoped MCP narrowly so AI agents can't do anything you didn't explicitly approve.

What it can do

Draft text-only posts for Facebook, LinkedIn, X (Twitter), Threads, and Bluesky.
Schedule drafts for the future within your plan's scheduling window.
Read your analytics: views, likes, comments, shares, follower counts, top-performing posts.
List your connected platforms and your pending posting quota.
Read your post history, including which posts succeeded and which failed.

What it can't do

Publish without your approval. Every draft requires you to tap Approve in the Socialync app. No auto-approve mode exists.
Upload or attach media. No images, no video, no GIFs. To post media, schedule it directly in the Socialync app.
Post to Instagram, TikTok, or YouTube. Those platforms require media, so they're excluded from MCP.
Edit or delete your existing scheduled posts. Use the Socialync app for that.
Bypass platform rate limits. Twitter, LinkedIn etc. enforce their own daily limits — Socialync surfaces these to the AI but the platforms themselves are the ceiling.

Setup (3 steps)

1
Generate an API key
Open Socialync settings, scroll to API Keys, and tap “Generate Key.” You'll see the key once — copy it somewhere safe immediately. (Requires the Business plan.)
Open API Keys
2
Add Socialync to your MCP client
In Claude Desktop, open Settings → Developer → Edit Config, paste the snippet below, and replace YOUR_SOCIALYNC_API_KEY with the key you just generated.
```
{
  "mcpServers": {
    "socialync": {
      "transport": {
        "type": "http",
        "url": "https://socialync-mcp-ntgtgrzanq-ue.a.run.app/mcp",
        "headers": {
          "Authorization": "Bearer YOUR_SOCIALYNC_API_KEY"
        }
      }
    }
  }
}
```
Other MCP clients (ChatGPT, Cursor, Cline, custom agents) use the same Streamable HTTP transport at https://socialync-mcp-ntgtgrzanq-ue.a.run.app/mcp with a Bearer token. Configuration shape may vary.

Restart Claude and try it
After restarting Claude Desktop, ask it something like:
“Draft a LinkedIn post about consistency in fitness for tomorrow morning at 9am.”
Claude will create a draft. Open your draft inbox to review and approve it.

Things to try

Sample prompts that show off what the MCP server can do.

“Draft a Twitter post announcing our Q3 product launch and schedule it for next Monday at 10am EST.”

“Show me my top 5 performing posts this month and tell me what they have in common.”

“Which platforms am I connected to right now?”

“Compare my engagement rate this week vs last week across all platforms.”

“Draft the same announcement for LinkedIn and Threads, with a longer caption for LinkedIn and shorter for Threads.”

Every post Claude prepares lands in your draft inbox. Drafts expire after 24 hours if you don't approve them.
