Published tool inventories disagree.\n\n## Before you call either\n\n### Kling AI API\n\n1. Sign a JWT (HS256) with `iss` set to your AccessKey and a 30 minute `exp`, then send it as a bearer token\n2. Generate a new key pair if you need Kling 3.0 Turbo. Older keys don't reach it\n3. Create with POST /v1/videos/text2video or /v1/videos/image2video, then poll the task id until it succeeds\n4. Don't plan on Kling 4.0 or clips over 10 seconds through this API yet. Kling 4.0 isn't on the developer platform as of 17 October 2026\n5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls\n\n### Popcraft MCP\n\n1. Preview credit cost and obtain approval before submitting paid generation.\n2. Discover the current tool list instead of assuming the advertised count.\n3. Poll the existing job rather than resubmitting a generation after a timeout.\n\n## Questions\n\n### Which is better for AI agents, Kling AI API or Popcraft MCP?\n\nPopcraft MCP scores 37.9 (F) on agent readiness against Kling AI API's 21.7 (F), and leads in 4 of 7 scored categories. Kling AI API leads on maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Kling AI API and Popcraft MCP need an API key?\n\nKling AI API needs an API key. Popcraft MCP uses an OAuth sign-in.\n\n### Can an agent call Kling AI API and Popcraft MCP without installing anything?\n\nYes. Kling AI API has a hosted endpoint at https://api-singapore.klingai.com and Popcraft MCP at https://popcraft.ai/api/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/kling-vs-popcraft-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/kling-vs-popcraft-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"kling\", \"b\": \"popcraft-mcp\"}`.
