Social media MCP server for Claude, Cursor and ChatGPT

Create an API key at app.socifyr.com/dashboard/api-keys. Each key belongs to one workspace, so the connector acts on that workspace. Then pick your client.

claude mcp add --transport http socifyr https://api.socifyr.com/api/mcp \
  --header "Authorization: Bearer sk_your_key_here"

{
  "mcpServers": {
    "socifyr": {
      "url": "https://api.socifyr.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${env:SOCIFYR_API_KEY}"
      }
    }
  }
}

1. claude.ai: open Settings, Connectors, Add custom connector. Enter https://api.socifyr.com/api/mcp, expand Advanced, add the header Authorization: Bearer sk_your_key_here, and leave sign-in set to "No sign-in required". The header is the authentication.
2. ChatGPT: needs a plan with Connectors and developer mode (Plus, Pro, Team or Enterprise). Create a connector with the same URL and the same Authorization header.

Once the connector is enabled, plain language is enough. The assistant picks the tool and fills the arguments.

• "List my Socifyr connections." (calls list_connections and reads back your slugs)
• "Post 'just shipped a new feature' to LinkedIn and X." (calls post_text with both slugs)
• "Schedule these five posts for next week at 9am on linkedin-mybrand." (calls schedule_posts)
• "Did my last post go out everywhere? Retry anything that failed." (calls check_post_status, then retry_post)
• "Which accounts are about to expire? Renew them." (calls list_connections, then refresh_connection)

Scheduling requires a paid plan. Free workspaces can publish immediately but not schedule. See how scheduling works.

list_connections flags accounts as expiring or needing reconnect, and a failed post reports reconnect_required. The assistant can handle both without you opening the dashboard. It calls refresh_connection first. If the platform cannot refresh, it calls reconnect_connection, which returns a link that works once and expires after 10 minutes. The owner opens it and approves the same account, and the slug and any scheduled posts keep working.

{ "connection": "instagram-mybrand" }

The full walkthrough is in OAuth token expiry and how to refresh or reconnect accounts.

Keys can carry guardrails: a daily post cap, a monthly X spend cap, and a mode that routes every post into an approval queue for a human. A key with any guardrail cannot manage keys, members, webhooks or connections, so it cannot lift its own limits. Read how to give an AI agent safe access to social accounts.
