問題文
A team must call three external systems: one with a simple REST endpoint used in a single topic, one with an OpenAPI definition already used by other apps, and one exposing MCP tools. Which mapping fits?
選択肢
- A Send HTTP request node in the topic, the existing custom connector as a tool, and an MCP server connection.
- A Send HTTP request node for all three, because every one of the systems is reachable over HTTP and a single mechanism keeps the design consistent.
- A2A for all three, because A2A is interoperable across frameworks.
- MCP for all three, because MCP is the newest integration mechanism.
