ChatGPT social media scheduling: how it connects#
ChatGPT social media scheduling works through a custom MCP connector: enable Developer Mode, add SkedCast's server URL, and sign in. Once connected, ask ChatGPT to schedule or check posts, and it confirms every write action with you first.
1. Turn on Developer Mode#
In ChatGPT, go to Settings → Apps & Connectors → Advanced settings, and enable Developer Mode. This is what unlocks arbitrary remote MCP servers with full read/write tool calls — the standard Connectors screen only offers a narrower, read-oriented set of built-in integrations.
2. Add SkedCast as a custom connector#
Back in Connectors → Advanced, choose "Add connector" and paste SkedCast's MCP URL: https://api.skedcast.com/mcp.
3. Sign in and use it in a chat#
ChatGPT runs the OAuth flow against SkedCast. Once connected, toggle the SkedCast tool on for a conversation and ask it to schedule or check posts — each write action asks you to confirm before it runs.
Known limitations#
| What to know |
|---|
| Free ChatGPT accounts don't get Developer Mode; Plus and Pro can enable it for personal use. |
| On Business, Enterprise and Edu workspaces, a workspace admin has to review and publish the connector before members can use it — full read/write MCP support is rolling out there as a beta. |
FAQ
- Can I use SkedCast's MCP server on the ChatGPT free plan?
- Not today — Developer Mode, which is what enables a custom remote MCP connector with write access, is a Plus/Pro (and gated Business/Enterprise) feature.
- What can an agent do once it's connected?
- Whatever your SkedCast role and plan allow — the connection acts as you, not with elevated access. Read posts and analytics, schedule and revise posts, and act on approvals, all through the same tools listed on the MCP hub.
