MCP targets

MCP targets operate in aggregation mode — the gateway acts as an MCP server whose capabilities combine those of all its MCP targets. Clients see a single consolidated tools/list response that includes tools from all attached MCP targets. MCP targets support capability synchronization, semantic tool search, and three-legged OAuth (3LO) at the target level.

The following topics describe the MCP target types that you can add to your gateway.
