4 steps to connect
- Dify → Tools → Custom Tool → Create → choose the “OpenAPI” import method.
- Set the schema URL to `https://lucydomi.com/mcp/openapi.json` (OpenAPI 3.1 by default; if an older importer throws an error, add `?spec=3.0`).
- Set the auth type to API Key → Bearer and put the key in Authorization.
- After import, the 10 tools appear as workflow nodes — drag in the ones you need in an Agent or a workflow.
OpenAPI spec URL
https://lucydomi.com/mcp/openapi.json3.1 is the default; for older importers, add ?spec=3.0.
Note
China platforms and overseas platforms are two separate key groups, and one key cannot call across them — so a workflow needs two tool nodes, one per group.

Do I need to write code?
No. Every step on this page happens inside the client's own interface.
Can the key leak?
Stick to the client's own credential store or an environment variable reference, and never commit the key.
Can I use the China platforms right away?
Overseas platforms work right after sign-up; Douyin and Xiaohongshu give new accounts 5 free trial calls (no balance deducted), after which a cumulative top-up of $30 unlocks them.
