Connect PostKing to Claude, ChatGPT and Cursor

PostKing runs a hosted MCP server. Add it to your assistant as a remote connector, sign in to PostKing in the browser window that opens, and your assistant can work on your brands.

Claude.ai and Claude DesktopCopy Anchor Link

Both use the same custom connector.

1. Open Settings, then Connectors.
2. Choose Add custom connector.
3. Name it PostKing and paste https://mcp.postking.app/mcp.
4. Save, then choose Connect. Sign in to PostKing and approve access.
5. In a chat, enable the PostKing connector from the tools menu.

Menu names can differ slightly by plan and app version. Custom connectors are not available on every Claude plan; if you do not see the option, check your plan or ask your workspace admin.

Run this once in your terminal:

claude mcp add --transport http postking https://mcp.postking.app/mcp

Then start claude, run /mcp, select postking and choose Authenticate. A browser window opens for the PostKing sign-in.

Optional: install the PostKing skills so Claude Code knows the right tool order for posts, blogs, SEO and landing pages.

ChatGPTCopy Anchor Link

1. Open Settings, then Connectors. If custom connectors are hidden, enable developer mode under the advanced settings first.
2. Create a connector. Name it PostKing, set the server URL to https://mcp.postking.app/mcp, and choose OAuth for authentication.
3. Connect, sign in to PostKing and approve.
4. In a new chat, add the PostKing connector from the tools menu.

Where this lives in ChatGPT depends on your plan and workspace settings; admins may need to allow custom connectors.

CursorCopy Anchor Link

Add PostKing to your MCP config (~/.cursor/mcp.json for all projects, or .cursor/mcp.json in one project):

{
  "mcpServers": {
    "postking": {
      "url": "https://mcp.postking.app/mcp"
    }
  }
}

Open Cursor Settings, then MCP, and choose Connect next to postking. Sign in to PostKing in the browser window.

Other clientsCopy Anchor Link

Any client that supports remote MCP servers over Streamable HTTP with OAuth works. Give it the URL https://mcp.postking.app/mcp and let it run the sign-in. The server advertises its OAuth details through standard discovery, so clients that register themselves need nothing else.

Clients that only support local (stdio) servers cannot use this URL directly.
