Cursor

Add it for every project in ~/.cursor/mcp.json, or for one project in .cursor/mcp.json:

~/.cursor/mcp.json

{
  "mcpServers": {
    "postflow": {
      "url": "https://postflow.biz.id/api/mcp",
      "headers": { "Authorization": "Bearer ${env:POSTFLOW_API_KEY}" }
    }
  }
}

Cursor reads POSTFLOW_API_KEY from your environment. Leave out headers to sign in with OAuth instead: Cursor shows a Login button next to the server in Settings → MCP. Check the server shows its tools there, then use it from the agent chat.
