n8n

Use the current node (v1.2+; v1.4 is current). Version 1 only has an SSE Endpoint field and cannot reach Servicebay.

MCP Client Tool (on an AI Agent)

1. Add MCP Client Tool from the nodes panel (so you get the latest typeVersion).
2. Server Transport: HTTP Streamable (httpStreamable).
3. Endpoint: https://oauth.servicebay.io/mcp
4. Authentication: Bearer → sk_live_YOUR_KEY (or Header Authorization). OAuth2 credentials work if you registered a confidential client.

MCP Client (workflow step)

Same endpoint and transport. Tool list is fetched from the server; pick one tool per step.

Do not select SSE. Servicebay has no /sse lane — an SSE client will retry and fail. If a copied workflow still shows "SSE Endpoint", delete the node and add a fresh one.
